  • [Title] Metastatic acinar cell carcinoma of the pancreas responding to gemcitabine, 5-fluorouracil and leucovorin therapy: a case report.
  • Acinar cell carcinoma of the pancreas is rare tumour with a generally poor prognosis.
  • There are very few reports of tumour regression following chemotherapy.
  • In this case report, a patient with metastatic acinar cell carcinoma in the liver developed progressive disease after cisplatin/etoposide and then had progressive disease after weekly paclitaxel chemotherapy.
  • However, his tumour then responded to gemcitibine/5-flourouracil/leucovorin chemotherapy.
  • Herein, previously described chemotherapy regimens used for this rare tumour are reviewed.
  • This case represents the first reported metastatic acinar cell carcinoma responding to this regimen.

  • [Title] Microcystic adenocarcinoma of the prostate: a variant of pseudohyperplastic and atrophic patterns.
  • Cystic change in adenocarcinoma of the prostate is unusual and may be confused with benign cystic atrophy.
  • Limited data exist on the pathologic attributes of microcystic change in malignant prostatic glands.
  • The aim of this study was to assess histologic and immunohistologic characteristics of microcystic adenocarcinoma of the prostate.
  • This alteration was defined as cystic dilatation and rounded expansion of the malignant gland profile, with a flat luminal cell lining layer.
  • The greatest diameter of the dilated cancer glands was 0.4 to 0.9 mm, with a mean diameter 10-fold greater than adjacent small malignant glands.
  • The microcystic glands were typically adjacent to usual small acinar adenocarcinoma.
  • Atrophic features were seen at least focally in all cases, although many microcystic adenocarcinoma epithelia exhibited a moderate amount of cytoplasm.
  • Gleason grade 3 was the predominant grade of the adjacent nonmicrocystic malignant glands.
  • Ninety-six percent of the microcystic cases showed alpha-methylacyl CoA racemase overexpression and all cases showed complete basal cell loss (using 34betaE12 and p63 antibodies) in immunohistochemistry.
  • Microcystic adenocarcinoma of the prostate is a distinctive histomorphologic presentation of prostatic adenocarcinoma that is deceptively benign-looking at low magnifications.
  • Detection of intraluminal crystalloids or wispy blue mucin at low magnification, immunostains for alpha-methylacyl CoA racemase, and basal cells, and a search for adjacent usual small acinar adenocarcinoma are helpful diagnostic aids.
  • Diagnostic awareness of this growth pattern of prostatic carcinoma is important to avoid underdiagnosis of adenocarcinoma of the prostate.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • Accidental discovery of androgen receptor (AR) expression in high-grade salivary gland cancer led to evaluation of that finding.
  • In this study we evaluated the immunohistochemical expression of AR in a series of 37 formalin-fixed, paraffin-embedded malignant salivary gland tumors using two commercially available antibodies.
  • Nuclear immunoreactivity for AR was demonstrated in 3 of 4 salivary duct carcinomas, 2 of 7 adenocarcinomas NOS and 1 of 2 carcinoma ex pleomorphic adenoma for both antibodies.
  • There was no immunoreactivity seen in 13 adenoid cystic carcinomas, 7 mucoepidermoid carcinomas and 4 acinic cell carcinomas.
  • The expression of AR in high-grade salivary gland cancers suggests a possible role for AR in the clinical management of these neoplasms.

  • [Title] Correlation of human Bub1 expression with tumor-proliferating activity in salivary gland tumors.
  • Human Bub1 plays an important role at the spindle assembly check-point to prevent cell cycle progression following spindle damage.
  • We examined the expression of Bub1 mRNA and protein in 21 human salivary gland tumors (7 pleomorphic adenomas, 2 warthin tumors, 5 mucoepidermoid carcinomas, 3 adenoid cystic carcinomas and 4 acinic cell carcinomas) and 3 normal submandibular glands using real-time quantitative reverse transcription-polymerase chain reaction (RT-PCR) or western blotting.
  • The mean expression levels of Bub1 mRNA and protein were higher in malignant tumors (0.12+/-0.028/1.75+/-0.53) than normal submandibular glands (0.042+/-0.014/0.19+/-0.044) and benign tumors (0.058+/-0.01/0.97+/-0.44).
  • We found a significant association between the level of Bub1 mRNA/protein expression and clinical stage in malignant tumors (Mann-Whitney U test, p=0.019/p=0.016).
  • We analyzed its relation with the proliferative activity monitored by the Ki-67 labeling index by immunohistochemistry as well as the expression of proliferating cell nuclear antigen (PCNA) by Western blotting.
  • A significant correlation was found between Bub1 mRNA/protein expression and the Ki-67 labeling index in salivary gland tumors (Spearman's correlation coefficient by rank test, p=0.026/p=0.002).
  • These results indicate that increased expression of the human Bub1 gene is closely linked to abnormal cell proliferation in malignant conditions.

  • Genetic pathways of various types of pancreatic carcinoma are described.
  • There are many differences in the genetic pathway between duct carcinogenesis and acinar carcinogensis.
  • K-ras mutation is a key event in the early stage of pancreatic duct carcinogenesis and various gene alterations accumulate from precancerous ductal lesions until the development of carcinomas.
  • Therefore, inhibition of K-ras gene mutation might be important for the prevention, and the combination of therapeutic agents against some target genes might be needed for therapy of ductal carcinomas.

  • [Title] Cytomorphologic patterns in papillary cystic variant of acinic cell carcinoma of the salivary gland.
  • OBJECTIVE: To study the cytomorphologic profile of the papillary and cystic variant of acinic cell carcinoma (ACC-PCV) of the salivary glands.
  • However, common to all was a papillary pattern and a cystic fluid background with or without mucin blobs; that led to misdiagnosing the tumor as mucoepidermoid carcinoma on 2 occasions.
  • The granular cells were similar to those seen in the usual acinic cell carcinoma but were smaller.
  • The tumor did not show any acinar pattern and lacked naked nuclei in the background.
  • CONCLUSION: ACC-PCV is papillary and cystic and hence is often not recognized as acinic cell carcinoma.
  • However, papillary fragments of vacuolated cells or histiocytelike cells and granular cells are clues to the diagnosis.

  • [Title] Detection of C-KIT (CD117) molecule in benign and malignant salivary gland tumours.
  • C-KIT (CD117), a tyrosine kinase receptor, is involved in the growth and development of normal tissues and some types of neoplasms.
  • Archival formalin-fixed, paraffin-embedded sections of 40 benign and 57 malignant salivary gland tumours were retrieved and retrospectively studied immunohistochemically using a polyclonal C-KIT antibody in an Envision/HRP technique.
  • In addition five samples of chronic submandibular sialadenitis, five normal minor salivary glands and parotid or submandibular gland tissue adjacent to benign tumour were also studied.
  • C-KIT expression was observed in cases of adenoid cystic, acinic cell polymorphous low grade, epithelial-myoepithelial, carcinosarcoma and basal cell adenocarcinomas, as in luminal cells of pleomorphic adenomas, in serous acinar and only in intercalated and a small number of striated ductal cells of inflammatory salivary gland tissue, whereas normal salivary lobules were generally negative except a weak positivity of intercalated cells.
  • Contrary to other reports, this study suggests that, C-KIT protein does not appear to be an exclusively specific marker for benign or malignant salivary gland neoplasms, but may be useful in differential diagnosis of adenoid cystic carcinoma from polymorphous low grade adenocarcinoma.
  • Furthermore its expression in serous acinar cells in sialadenitis and intercalated ductal cells in normal and inflammatory lesions may indicate a possible participation in pathogenesis of both neoplastic and non-neoplastic salivary gland diseases.

  • This tumour was revealed by epigastric pain and weight loss.
  • There was a marked dilatation of the main pancreatic duct upstream, with tumour spreading within this duct.
  • The diagnosis of ACC was made on the fine needle aspiration cytology performed during endoscopic ultrasound examination.
  • On the pancreaticoduodenectomy specimen, the dilated main pancreatic duct (2.5 cm in diameter) was filled by an exophytic tumour.
  • These rare forms of ACC can be confused with intraductal papillary-mucinous neoplasms.

  • We present a 13-year-old girl with acinic cell carcinoma of the parotid gland.
  • Removal of the superficial lobe of the parotid gland (superficial parotidectomy) was performed because the tumor was completely encapsulated by fibrous tissue and had not invaded the deep parotid gland.
  • In our view, when tumors are completely encapsulated and do not adhere to the facial nerves, superficial parotidectomy is the best surgical treatment in children.

  • [Title] Acinic cell carcinoma of minor salivary glands: a clinical and immunohistochemical study.
  • PURPOSE: Acinic cell carcinoma is a rare malignant tumor of salivary glands.
  • The purpose of this study is to evaluate the clinical outcome of acinic cell carcinoma in a group of 11 patients, who were treated in our clinic, and to discuss the management as well as the immunohistochemical features and prognosis of this carcinoma.
  • MATERIALS AND METHODS: The study included 11 patients with acinic cell carcinoma of the minor salivary glands who were treated in our clinic.
  • Immunohistochemical assay of expression of Ki-67, p53, EGFR, and c-erbB-2/neu markers was performed on specimens of all tumors.
  • Two patients died of another cause free of the disease 9 and 10 years after the initial treatment, and 2 patients died of the disease (local recurrence, distant metastases 2 and 3 years later).
  • Overexpression of immunohistochemical markers was evident for tumors with widespread metastases.
  • CONCLUSIONS: Acinic cell carcinoma is a rare malignant tumor of the salivary glands, characterized by an indolent clinical course with the potential for both local recurrence and distant metastases.
  • The immunohistochemical analysis of proliferation markers provides additional prognostic information for this tumor.

  • [Title] Surfactant protein A detection in primary pulmonary adenocarcinoma without bronchioloalveolar pattern.
  • BACKGROUND: Immunohistochemical studies in human lung carcinoma reported positive staining of tumor cells for surfactant protein A (SP-A), especially in peripheral airway cell carcinoma, which include bronchioloalveolar carcinoma and in some reports also papillary subtypes.
  • OBJECTIVE: The purpose of this study was to determine the SP-A expression in tumor cells of lung adenocarcinoma without a bronchioloalveolar pattern, classified according to the WHO.
  • METHODS: In total, 169 primary adenocarcinomas of the lung (109 acinar, 32 solid with mucin, 24 papillary and 4 mucinous) were examined by immunohistochemistry for SP-A expression.
  • RESULTS: Twenty-five percent of acinar, 38% of papillary and 3% of solid adenocarcinoma with mucin showed a positive intracytoplasmic SP-A reaction of the tumor cells.
  • None of the mucinous adenocarcinomas stained for SP-A.
  • This study included the largest number of acinar adenocarcinomas and solid adenocarcinomas with mucin studied for SP-A.
  • We clearly demonstrated that also primary lung adenocarcinoma without a bronchioloalveolar pattern can express SP-A.
  • A positive staining of hyperplastic type II cells surrounding the tumors or entrapped in the tumor could clearly be differentiated from the SP-A-positive stain of tumor cells.
  • CONCLUSION: These results support the theory that SP-A-producing cells may generate not only bronchioloalveolar and papillary carcinoma, but also other subtypes of lung adenocarcinoma.

  • Female MT-tgf alpha mice of the MT100 line developed pancreatic proliferation, acinar-ductal metaplasia, multilocular cystic neoplasms, ductal adenocarcinomas and prominent fibrosis, while the lesions in males were less severe.
  • Ela-myc transgenic mice with a mixed C57BL/6, SJL and FVB genetic background developed pancreatic tumors at 2-7 months of age, and half of the tumors were ductal adenocarcinomas, similar to what was reported originally by Sandgren et al 1.
  • However, in 20% of the mice, the tumors metastasized to the liver.
  • MT100/Ela-myc and MT-tgf alpha-ES/Ela-myc double transgenic mice developed not only acinar carcinomas and mixed carcinomas as previously reported but also various ductal-originated lesions, including multilocular cystic neoplasms and ductal adenocarcinomas.
  • The double transgenic tumors were more malignant and metastasized to the liver at a higher frequency (33%) compared with the Ela-myc tumors.
  • Sequencing of the coding region of p16ink4, k-ras and Rb cDNA in small numbers of pancreatic tumors did not identify mutations.
  • The short latency for tumor development, the variety of tumor morphology and the liver metastases seen in Ela-myc and MT-tgf alpha/Ela-myc mice make these animals good models for investigating new therapeutic and preventive strategies for pancreatic cancer.

  • Although several studies have reported that oropharyngeal infection with HPV may predispose to tumorigenesis, little is known about the etiological factors of salivary gland tumors and the presence of HPV.
  • We studied 9 parotid lesions for HPV infection including an oncocytoma, an acinic cell carcinoma, a high-grade adenocarcinoma, a low-grade polymorphous adenocarcinoma, a Warthin's tumor and 2 pleomorphic adenomas, a lymphoepithelial cyst and a lipoma of the parotid gland.
  • High viral load of highrisk genotypes of HPV was found in the oncocytoma, in one of the pleomorphic adenomas, and in the Warthin's tumor.
  • Finally, in situ PCR indicated that HPV16 amplification occurred in the salivary gland tumors.
  • This is the first time that highrisk HPV genotypes are detected in these histological types of parotid lesions, suggesting the possible involvement of the virus in the disease.

  • Fine needle aspiration is notoriously unreliable in recognizing the malignant nature of the parotid carcinoma, providing its precise classification, and establishing its grade.
  • A few malignant neoplasms are particularly prone to diagnostic error.
  • Acinic cell carcinoma is frequently interpreted as benign or even nonneoplastic; and low-grade lymphomas are often discounted as inflammatory processes.

  • Various parotid gland diseases are seen clinically, including inflammation, sialolithiasis, and benign and malignant tumors.
  • It is important to differentiate between these to make a correct diagnosis and for proper management.
  • Here, we investigated the relationship between tumor characteristics and pathology, and considered whether the former could be used to differentiate malignant from benign parotid gland diseases.
  • Two hundred and eighty-one patients (88.9%) had benign disease, and 35 (11.1%) had malignant disease.
  • The most common benign disease was pleomorphic adenoma (115 cases, 36.4%), but the most common disease in male patients was Warthin's tumor, a finding which, as far as we aware, has not been previously been reported in the literature.
  • The incidence of Warthin's tumor seems to be increasing.
  • In malignant disease, the most common was acinic cell carcinoma (8 cases, 22.9%).
  • Compared with benign disease, malignant parotid gland disease more often presents as a hard, painful, fixed and large mass (> 3 cm), and more often involves the deep lobe of the parotid gland.
  • Partial parotidectomy was adequate for most tumors, including pleomorphic adenoma.
  • However, there was no difference in transient facial palsy rate between benign and malignant parotid gland disease, although parotid gland cancer had a higher incidence of permanent facial palsy postoperatively.

  • [Title] Pancreatic-type acinar cell carcinoma of the stomach beneath a focus of pancreatic metaplasia of the gastric mucosa.
  • Acinar cell carcinoma is an uncommon type of carcinoma of the pancreas that can exceptionally arise in ectopic pancreatic tissue.
  • Herein, we report a case of a 52-year-old man with pancreatic-type acinar cell carcinoma of the stomach and concomitant pancreatic metaplasia of the adjacent nonneoplastic gastric mucosa.
  • There was neither clinical nor radiographic evidence of a tumor in the pancreas itself.
  • Macroscopically, an ulcerated tumor, measuring 4 x 1.7 cm, was found in the distal antrum.
  • Microscopically, the biopsy and the surgical specimen revealed a neoplasm with a predominantly trabecular architecture composed of moderately atypical cells with finely dispersed chromatin and indistinct nucleoli.
  • The neoplastic cells and those of the adjacent metaplastic mucosa were both strongly immunoreactive for alpha-1-antitrypsin, consistent with pancreatic acinar cell differentiation.
  • Ectopic pancreatic-type acinar cell carcinoma is an extremely rare condition, having been previously reported only in 5 occasions, none of them in association with pancreatic acinar cell metaplasia of the gastric mucosa.

  • [Title] Pattern of carcinoma of oral cavity reporting at dental department of Ayub medical college.
  • BACKGROUND: Carcinoma of oral cavity is amongst the first ten commonest malignancies in Pakistan.
  • METHODDS: This clinicopathological study consists of cases of carcinoma of oral cavity presenting to dentistry department of Ayub Medical College Abbottabad during 1993-2003.
  • RESULTS: There were 50 carcinoma cases in the study, including 30 (60%) males and 20 (40%) females.
  • Among these, 47 (94%,) were diagnosed as squamous cell carcinomas, that consisted 30 (63.82 %) males and 17 (36.17%) females.
  • The other 6 % lesions were histologically diagnosed as malignant melanoma, adenocarcinoma and acinar cell carcinoma.
  • The age of squamous cell carcinoma cases was 41-71 years.
  • The maximum number of squamous cell carcinomas (34%) effected buccal mucosa.
  • CONCLUSION: The results of this study are comparable with other such studies done in Pakistan and else where in the world showing commonality of factors associated with the development of the disease in this region of the country, which necessitates a detailed prospective study.

  • INTRODUCTION AND OBJECTIVES: Varieties of prostatic adenocarcinoma whose architectural and cytological appearance mimicked benign lesions have been reported in recent decades.
  • Such neoplasms include xanthomatous (foamy) carcinoma and pseudohyperplastic carcinoma.
  • We recently studied five carcinomas showing a cytoarchitectural combination of both neoplasms which were confused with benign glandular proliferations.
  • METHODS: Five cases (1.8%) of pseudohyperplastic carcinoma showing xanthomatous changes were selected from a total of 280 biopsies showing prostate carcinoma.
  • Neoplasms showed minimal atypia and consisted of mid- to large-sized glands arranged in nests resembling hyperplastic nodules.
  • Several useful criteria for diagnosis of acinar carcinoma, such as perineural infiltration, mitosis, crystalloids, blue secretions, and prostatic intraepithelial neoplasm, were absent.
  • CONCLUSIONS: Prostatic carcinoma with a pseudohyperplastic pattern and xanthomatous changes mimics hyperplastic glands.

  • [Title] Adenoid cystic/basal cell carcinoma of the prostate strongly expresses HER-2/neu.
  • Adenoid cystic/basal cell carcinoma (ACBCC) is a rare neoplasm in the prostate.
  • The HER-2/neu (c-erbB-2) gene has been reportedly overexpressed in adenoid cystic carcinomas in other organs, but its status in prostatic ACBCC was uncertain.
  • Ten acinar adenocarcinomas of varying grades were also immunostained as controls.
  • Protein and mRNA expression were 2+ to 3+ (of 3+) in all patients with ACBCC, compared to a breast cancer control with strong reactivity, whereas protein expression was noted in only one acinar carcinoma and mRNA expression was absent in all acinar carcinomas.
  • Benign acini expressed HER-2/neu only in the basal layer.
  • The finding of strong, consistent HER-2/neu expression in ACBCC suggests that treatment with Herceptin (trastuzumab) may be effective in patients with this rare tumour.

  • We present the case of a 23-year-old woman with a parotid gland tumor, the fine-needle aspiration biopsy smears of which showed epithelial cells with wide cytoplasm, isolated or arranged in micropapillary groups together with psammoma bodies.
  • The surgical specimen contained a 5-cm tumor with the histologic features of an acinic cell carcinoma (ACC) with papillary areas.
  • Notably, the cells of the tumor seemed to follow a sequence from large cells with rounded nuclei with open chromatin and prominent nucleoli to vacuolated cells with granular material, and finally to cells undergoing apoptosis.
  • This finding was followed by the appearance of concentrically laminated, round to polygonal, Congo red-positive, birefringent bodies that in areas accumulated and formed extensive areas with massive deposits.

  • [Title] Cytology and histology have limited added value in prognostic models for salivary gland carcinomas.
  • Univariate analyses on malignant salivary gland tumors report a strong relation of histological subtypes and prognosis.
  • In order to study the prognostic value of cytology and histology in salivary carcinoma we performed multivariate analyses on 666 newly diagnosed patients.
  • In multivariate analyses sex, tumor size, N- and M-staging, localization, comorbidity, skin involvement and pain were independent predictors of survival.
  • Histology was an independent prognostic factor, mainly because acinic cell carcinoma acted differently from the other histological subtypes.
  • The added prognostic value of cytology and/or histology factors in salivary carcinoma is limited, largely due to the combined prognostic value of other prognostic factors such as tumor size, N- and M-classification and comorbidity.

  • [Title] Ductal adenocarcinoma of the prostate: increased mortality risk and decreased serum prostate specific antigen.
  • PURPOSE: The clinical significance of ductal prostatic carcinoma is not well-defined.
  • In a population based cancer registry we identified a large group of patients with ductal carcinoma to characterize the impact of the ductal subtype on presentation and survival in men with prostate cancer.
  • MATERIALS AND METHODS: We used a national cancer registry to identify incident cases of ductal and acinar adenocarcinoma from 1996 to 2006.
  • Prostate specific antigen values were available for 2004 to 2006 and used to assess differences in Gleason grade and serum prostate specific antigen between ductal and acinar cancer cases at diagnosis.
  • RESULTS: We identified 442,881 acinar and 371 ductal cases.
  • Ductal cases were more likely to present with distant disease (12% vs 4%, p <0.001) and be poorly differentiated (50% vs 32%, p <0.001).
  • In men with nondistant disease at diagnosis ductal histology was associated with 2.2-fold (CI 1.4-3.5) increased disease specific mortality.
  • CONCLUSIONS: In what is to our knowledge the largest series of this histological subtype ductal cancer cases were more likely to present with advanced stage cancer and lower prostate specific antigen, suggesting that timely disease detection is a significant challenge.
  • Also, men with locoregional disease were more likely to die of the disease.

  • [Title] Immunohistochemical expression of prostate stem cell antigen in cystoprostatectomies with incidental prostate cancer.
  • High expression of prostate stem cell antigen (PSCA) has been shown to be associated with adverse prognostic features in clinically-diagnosed prostate cancer.
  • The aim of this study is to analyze PSCA expression in cystoprostatectomies with incidental prostate carcinoma (PCa).
  • PSCA expression was evaluated immunohistochemically in normal-looking epithelium (NEp), high-grade prostatic intraepithelial neoplasia (HGPIN) and pT2a Gleason score 6 acinar adenocarcinoma.

  • [Title] Sinonasal acinic cell carcinoma: a clinicopathologic study of four cases.
  • BACKGROUND: Acinic cell carcinoma is a low-grade malignant epithelial salivary gland neoplasm with a predilection for the parotid gland.
  • To date, only 11 cases of sinonasal acinic cell carcinomas have been reported in the English-language literature.
  • We present the clinicopathologic features of four sinonasal acinic cell carcinomas.
  • METHODS: The demographic data and pathologic material of four patients with sinonasal acinic cell carcinoma identified from the files of the Department of Pathology at The University of Texas M. D.
  • Histologically, all tumors were composed of round to ovoid cells with clear and/or basophilic granular cytoplasm and round, hyperchromatic, small, eccentrically located nuclei.
  • CONCLUSIONS: Sinonasal acinic cell carcinoma is a distinct low-grade carcinoma that can be distinguished from other neoplasms by light microscopy and histochemical staining methods.
  • Pathologists and surgeons should be aware of the occurrence of this type of salivary gland neoplasm in the sinonasal tract.

  • [Title] Expression of novel markers of pancreatic ductal adenocarcinoma in pancreatic nonductal neoplasms: additional evidence of different genetic pathways.
  • Solid pseudopapillary tumor, pancreatoblastoma, undifferentiated carcinoma with osteoclastic-like giant cells, and acinar cell carcinomas are rare pancreatic nonductal neoplasms.
  • Compared to the significant advances in our understanding of the pathogenesis of pancreatic ductal adenocarcinomas in the last decades, the molecular mechanisms underlying pancreatic nonductal neoplasms are poorly understood.
  • In order to elucidate their molecular pathogenesis, we constructed tissue microarrays to study the expression of some novel pancreatic ductal adenocarcinoma-associated tumor markers in these nonductal pancreatic neoplasms.
  • We analyzed nine markers including tumor suppressor gene (14-3-3 sigma), proliferation marker (topoisomerase II alpha), epithelial markers (prostate stem cell antigen, mesothelin and cytokeratin 19), stromal markers (fascin, hsp47 and fibronectin), and gamma-synuclein whose function is not delineated.
  • In addition, we included tumor suppressor gene DPC4 and oncogene Beta-catenin to further confirm their expression in pancreatic nonductal tumors.
  • Our results showed that in contrast to pancreatic ductal adenocarcinomas that show loss of Dpc4 protein in 55% of cases, loss of Dpc4 expression is absent in pancreatic nonductal neoplasms.
  • Expression of 14-3-3 sigma is frequently seen in both pancreatic nonductal neoplasms (25-100%) and ductal adenocarcinomas (89%).
  • Aberrant nuclear expression of beta-catenin is common in pancreatic nonductal neoplasms, specifically in solid pseudopapillary tumors (88%) and pancreatoblastomas (100%) but is rarely seen in pancreatic ductal adenocarcinomas (<5%).
  • Expression of topoisomerase II alpha is not seen in solid pseudopapillary tumors and undifferentiated carcinomas with osteoclastic-like giant cells but is focally seen in pancreatoblastomas (50%) and acinar cell carcinomas (85%).
  • Expression of PSCA and mesothelin was observed in pancreatic nonductal neoplasms but their expression was seen less frequently (0-50%) and weaker than that in pancreatic ductal adenocarcinomas (60-100%).
  • CK19, a marker of pancreatic ductal adenocarcinomas, is not expressed in pancreatic nonductal neoplasms.
  • Our findings indicate pancreatic nonductal neoplasms have distinctive patterns of protein expression relative to pancreatic ductal adenocarcinomas and suggest that pancreatic nonductal neoplasms have different genetic pathways from the more common pancreatic ductal adenocarcinomas.

  • Differential diagnosis of neck tumours puts precedence on diagnosing neoplastic lesions.
  • In the case of neck tumours, these are unfortunately late signs, but in patients with a primary neoplastic focus within the head and neck, neck tumour is often the first sign of the disease.
  • The authors describe a clinical case of neck tumour with initially unclear etiology.
  • The preoperative diagnostics including ultrasonography, thin-needle puncture, MRI, carotid angiography and videostroboscopy was significant for surgical treatment planning; yet it was the intraoperative clinical picture which indicated that the tumour derived from the inferior parotid pole.
  • The preoperative histopathological diagnosis using thin-needle biopsy: cellulae carcinomatosae and the clinical picture resulted in block operation with neck lymphatic system removal and tissue defect reconstruction by means of a pectoral flap.
  • The histopathological examination confirmed non-cornifying basal cell epithelioma only in the essential lesion with no metastases to lymph nodes and surrounding tissue margins free of infiltrates.
  • Two and a half years after the procedure, the patient presented with a tumour localized on the front thoracic wall and two rapidly enlarging tumours in the nape of the neck.
  • In the collected specimen of the tumour on the front thoracic wall, a diagnosis of acinic cell carcinoma was made.

  • [Title] Prognostic relevance of cell proliferation in major salivary gland carcinomas.
  • Several proliferation markers, such as DNA ploidy, Ki67, MiB1 and proliferating cell nuclear antigen have been shown to correlate with clinical course and prognosis in several epithelial tumours and lymphomas.
  • In the present study, the prognostic relevance of these markers was evaluated in major salivary gland carcinomas.
  • A sample of 36 cases out of 85 patients submitted to surgery for major salivary gland carcinomas at our institution between 1987 and 1997 were studied.
  • The sample comprised 8 adenoid-cystic carcinomas, 6 ductal carcinomas, 11 mucoepidermoid carcinomas and 11 acinic cell carcinomas.
  • Instead, the proliferative tumour cell fraction, evaluated by MiB1, was statistically correlated with prognosis.
  • Of particular interest were MiB1 values in acinic cell carcinomas for which grading is challenging and lacks consensus.
  • In our group of acinic cell carcinomas, survival correlated with values of MiB1 > or < 15 with p = 0.009 in Log rank test.
  • Indeed, "growth fraction" in acinic cell carcinomas may stratify different classes of risk.

  • [Title] Shared TP53 gene mutation in morphologically and phenotypically distinct concurrent primary small cell neuroendocrine carcinoma and adenocarcinoma of the prostate.
  • BACKGROUND: Small cell carcinoma of the prostate is an uncommon neoplasm, the origin of which has been controversial.
  • To address this, we performed transcriptome profiling and TP53 sequencing of concurrent small cell and prostatic adenocarcinoma to determine the relationship between these entities.
  • METHODS: We identified an unusual case of primary prostate cancer that contained adjacent acinar adenocarcinoma (Gleason score 4 + 3 = 7) and small cell carcinoma.
  • We performed laser capture microdissection to isolate tumor components and performed gene expression and TP53 gene sequence analysis on each component, with results validated by immunohistochemistry for PSA, PSAP, PSMA, androgen receptor, NKX 3.1 and neuroendocrine markers.
  • RESULTS: Transcriptome profiling of the carcinoma components identified 99 genes with a greater than 10-fold differential expression between prostatic adenocarcinoma and small cell carcinoma, many of which have not been previously reported in prostate cancer.
  • The small cell carcinoma component demonstrated upregulation of proliferative and neuroendocrine markers and tyrosine kinase receptors, and downregulation of cell adhesion molecules, supporting the aggressive nature of this form of carcinoma.
  • CONCLUSIONS: This is the first report of a primary small cell carcinoma of the prostate subjected to extensive molecular analysis and the first to show a clonal relation between two morphologically distinct prostate cancer types.
  • The evidence of progression to small cell carcinoma may yield important insights into the pathogenesis of this entity and provide a novel spectrum of molecular markers to further dissect cellular pathways important in tumor progression.

  • Cystadenocarcinoma is a rare malignant tumor, with an estimated incidence of 2% of malignant salivary gland tumors.
  • Cytological diagnosis of cystadenocarcinoma is important for differential diagnosis between benign lesions and malignant tumors with cystic growth.
  • We report a case of cystadenocarcinoma causing difficulty in cytological diagnosis.
  • Preoperative fine-needle aspiration cytology (FNAC) showed a small number of tumor cell clusters in the cystic fluid.
  • Tumor cells had a small vacuolated, soap-bubble appearance in the cytoplasm.
  • The papillary-cystic variant of acinic cell carcinoma (ACC-PCV) was suggested from these findings on FNAC.
  • Histologically, the tumor was not encapsulated, but formed large cystic spaces against a background of fibrous connective tissue.
  • The tumor cells in the cystic dilated duct showed papillary structures, which were continuous with the lining cuboidal cells.
  • As tumor cells with a small vacuolated, soap-bubble appearance of the cytoplasm are common findings of both cystadenocarcinoma and ACC-PCV, they are of little use for differentiation; however, they are so characteristic that the majority of benign salivary gland lesions with cystic structures can be excluded, if enough attention is paid.

  • This study on 279 tumours of the salivary glands was conducted to analyse whether the assessment of DNA ploidy by flow cytometry may assist histopathology in discriminating benign from malignant types of tumours.
  • The group of benign tumours included 164 pleomorphic adenomas, 51 Warthin's tumours, 7 basal cell adenomas, 2 lipomas as well as 5 other different tumours.
  • All of the 229 benign tumours were diploid.
  • The malignant tumours consisted of 18 adenoid cystic adenomas, 10 mucoepidermoid carcinomas, 5 acinic cell carcinomas, 5 carcinoma in pleomorphic adenoma as well as of 12 other malignancies belonging to 7 different tumour entities.
  • Twelve of 50 malignant salivary gland tumours were aneuploid.
  • In three cases which initially were taken for pleomorphic adenomas by routine histological examination, aneuploid cell populations exposed by DNA flow cytometric analysis gave rise to a closer inspection of the suspect lesions.
  • Examination of consecutive slides actually revealed small assemblies of carcinoma cells that required a final diagnosis as non-invasive carcinoma in pleomorphic adenoma.
  • The most obvious value of DNA flow cytometry in salivary gland tumours is thus its contribution to assist histopathology in identifying potentially malignant lesions.

  • [Title] [Malignant epithelial parotid tumors: CT imaging and histopathologic correlation].
  • BACKGROUND & OBJECTIVE: Malignant epithelial parotid tumors have various histopathologic types.
  • This study was to analyze CT features of malignant epithelial parotid tumors to evaluate the diagnostic value of CT in the characterization of malignant epithelial parotid tumors.
  • METHODS: CT reports of 29 patients with malignant epithelial parotid tumors (8 at low grade and 21 at intermediate or high grade), confirmed by histopathology in Cancer Center of Sun Yat-sen University, were reviewed.
  • RESULTS: Of the 8 cases at low grade, 4 were well-differentiated mucoepidermoid carcinoma, 3 were acinic cell carcinoma, and 1 was epithelial-myoepithelial carcinoma; 3 had sharp margin, 3 had partly unsharp margin, and 2 had unsharp margin; 5 had regular contour, and 3 had irregular contour; all were enhanced obviously; 2 showed homogeneous appearance, and 6 showed inhomogeneous appearance with low-density areas; none had adjacent infiltration; 3 had lymph node metastasis.
  • Of the 21 cases at intermediate or high grade, 5 were poorly-differentiated squamous cell carcinoma, 8 were malignant pleomorphic adenoma, 2 were adenocarcinoma, 1 was lymph-epithelial carcinoma, 4 were mucoepidermoid carcinoma, and 1 was adenoidcystic carcinoma; 5 had sharp margin, 7 had partly unsharp margin, and 9 had unsharp margin; 10 had regular contour, and 11 had irregular contour; 17 were enhanced obviously, and the 4 cases of malignant pleomorphic adenoma were enhanced slightly; 9 showed homogeneous appearance, and 12 showed inhomogeneous appearance with low-density areas; 8 had adjacent infiltration (the fat space between tumor and the parotid bed disappeared); 6 had lymph node metastasis.
  • CONCLUSIONS: To some extent, CT features of malignant epithelial parotid tumors are correlated to the differentiation of tumor cells.
  • Moreover, tumor size and histologic subtype should be considered to make a more accurate imaging diagnosis.

  • [Title] Clinical prognostic factors in malignant parotid gland tumors.
  • OBJECTIVE: To analyze the factors in parotid malignant epithelial tumors influencing recurrences and disease-specific survival.
  • The influence of selected factors on the 10 year disease-specific survival was analyzed using the Kaplan-Meier actuarial method and the log-rank test.
  • RESULTS: Forty patients had mucoepidermoid carcinoma, 18 patients adenocarcinoma NOS, 18 patients acinic cell carcinoma, 15 patients adenoid cystic carcinoma, 11 patients malignant mixed tumor, 11 patients salivary duct carcinoma, and 13 patients other pathology.
  • Patients with high-grade tumors and high-stage tumors had the worst prognosis according to the multivariate analysis.
  • The 10-year disease-specific survival was 97% for stage I, 81% for stage II, 56% for stage III, and 20% for stage IV.
  • CONCLUSION: The grade of the tumor and stage were the most important prognostic factor.

  • [Title] Cytologic diagnosis of pulmonary adenocarcinoma with micropapillary pattern: does it correlate with the histologic findings?
  • Micropapillary adenocarcinoma is associated with poor-prognosis in several organs including the lung.
  • The presence of small tight balls of neoplastic cells devoid of fibrovascular core in cytological preparations (micropapillary tufts) has been described as characteristic of micropapillary adenocarcinoma.
  • The cytological material of 46 cases of histologically proven pulmonary adenocarcinoma with a micropapillary component was compared to 33 cases with no micropapillary component to determine the specificity of micropapillary tufts for the histologic diagnosis of micropapillary adenocarcinoma.
  • Other histologic patterns of invasive pulmonary adenocarcinomas (acinar, papillary, and solid) were also compared with patterns of neoplastic cell aggregates in cytological preparations.
  • The positive predictive value for the cytologic diagnosis of a micropapillary component in lung adenocarcinomas was of 64%.
  • Therefore, the detection of micropapillary tufts in cytology is not specific for the diagnosis of a pulmonary micropapillary adenocarcinoma in the lung.

  • [Title] Diagnostic approach to pancreatic tumors with the specimens of endoscopic ultrasound-guided fine needle aspiration.
  • Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) has enabled clinicians to histologically diagnose pancreatic tumors.
  • Using immunostaining of CK7, CDX2, neuroendocrine markers and KRAS mutation analysis, we examined 57 FNA cell block sections and 61 surgically-resected specimens (25 invasive ductal carcinomas, 25 endocrine tumors, and 11 acinar cell tumors).
  • In the majority of the matched pairs, the diagnoses between EUS-FNA and surgical specimens were concordant using the following criteria: neuroendocrine markers negative, CK7 positive, and mutated KRAS gene for invasive ductal carcinomas; neuroendocrine markers diffusely positive, CK7 and CDX2 negative, and wild-type KRAS gene for well-differentiated endocrine tumors; and neuroendocrine markers no more than focal positive, CK7 and CDX2 with various staining patterns, and wild-type KRAS gene for acinar cell carcinomas.
  • Expression of CK7 and/or CDX2 in addition to KRAS mutations were occasionally seen in endocrine carcinomas, but not in well-differentiated endocrine tumors, suggesting that ductal differentiation in an endocrine tumor may be a predictor of aggressive disease.
  • The usefulness of these markers was confirmed using 13 additional pancreatic tumors, prospectively.
  • Although minimal in selection, these markers are helpful in making diagnosis from EUS-FNA specimens of the major pancreatic tumors.

  • [Title] Curative resection of a primarily unresectable acinar cell carcinoma of the pancreas after chemotherapy.
  • BACKGROUND: Acinar cell carcinoma (ACC) represents only 1-2% of pancreatic cancers and is a very rare malignancy.
  • At the time of diagnosis only 50% of the tumors appear to be resectable.
  • MRI-imaging showed a tumor within the head of the pancreas concomitant with Serum-Lipase and CA19-9.
  • Endosonographic fine needle biopsy confirmed an acinar cell carcinoma.
  • Laparotomy presented an locally advanced tumor with venous infiltration that was consequently deemed unresectable.
  • Twelve months later, the patient was in stable condition, and CT-scanning showed an obvious reduction in the size of the tumor.
  • Histopathological examination gave evidence of a diffuse necrotic ACC-tumor, all resection margins were found to be negative.
  • Eighteen months later, the patient showed no signs of recurrent disease.

  • Oral administration of gefitinib to female transgenic mice from 5 to 14 weeks of age reduced tumor multiplicity from 9.6 +/- 0.82 to 0.58 +/- 1.1 (83%).
  • We observed a decrease in the number and size of lobules and lobular nodules in treated mice with a reduction in the overall disease burden per gland.
  • The development of acinic cell carcinoma in the parotid glands of these animals was also reduced coincident with decreased stromal involvement during progression.
  • Gefitinib eliminated phosphorylation of HER2 and HER3 and signaling through MAPK and Akt in lobular hyperplasias and carcinomas.
  • These studies demonstrate the critical role of HER2 signal transduction in the onset and progression of HER2/neu-dependent breast cancer and suggest a role for specific inhibitors to prevent the outgrowth of early hyperplastic disease.

  • [Title] Obligate basal cell component in salivary oncocytoma facilitates distinction from acinic cell carcinoma.
  • The differential diagnosis between benign salivary oncocytoma (ONC) and low-grade malignant acinic cell carcinoma (ACC) can be difficult due to a significant histomorphological overlap of the structural and cytological presentation of both tumor types.
  • To the best of our knowledge a comprehensive study comparing (immuno-)histological markers in cases of difficult differential diagnosis between ONC and ACC has not yet been performed.
  • The statistically significant stronger expression of CK7 in ONC and stronger expression of PAS and alpha-amylase in ACC in routine practice each is hampered by a pronounced overlap between both tumor groups.
  • The obligate presence of an additional small basal cell component in all cases of ONC, demonstrable with p63 and CK5/6, enables a straightforward distinction from ACC, being constantly devoid of a basal cell component.
  • The detection of this basal cell component in ONC in routine Hematoxylin-eosin stain is difficult and in some cases not possible; therefore, immunohistochemistry with p63 or CK5/6 is recommended for selected cases.

  • [Title] Gene expression profiles of ductal versus acinar adenocarcinoma of the prostate.
  • Ductal adenocarcinoma is an uncommon variant of prostatic adenocarcinoma with a generally more aggressive clinical course than usual acinar adenocarcinoma.
  • However, the molecular distinction between ductal and acinar adenocarcinomas is not well characterized.
  • The aim of this investigation was to evaluate the relatedness of ductal versus acinar prostatic adenocarcinoma by comparative gene expression profiling.
  • Archived, de-identified, snap frozen tumor tissue from 5 ductal adenocarcinomas, 3 mixed ductal-acinar adenocarcinomas, and 11 acinar adenocarcinomas cases were analyzed.
  • All cases of acinar and ductal adenocarcinomas were matched by Gleason grade.
  • RNA from whole tissue sections of the 5 ductal and 11 acinar adenocarcinomas cases were subjected to gene expression profiling on Affymetrix U133Plus2 microarrays.
  • Independently, laser-capture microdissection was also performed on the three mixed ductal-acinar cases and five pure acinar cases to isolate homogeneous populations of ductal and acinar carcinoma cells from the same tumor.
  • Seven of these laser-capture microdissected samples (three ductal and four acinar cell populations) were similarly analyzed on U133Plus2 arrays.
  • Analysis of data from whole sections of ductal and acinar carcinomas identified only 25 gene transcripts whose expression was significantly and at least two-fold different between ductal and acinar adenocarcinomas.
  • A similar analysis of microdissected cell populations identified 10 transcripts, including the prolactin receptor, with more significant differences in expression of 5- to 27-fold between ductal and acinar adenocarcinomas cells.
  • Overexpression of prolactin receptor protein in ductal versus acinar adenocarcinoma was confirmed by immunohistochemistry in an independent set of tumors.
  • We conclude that ductal and acinar adenocarcinomas of the prostate are strikingly similar at the level of gene expression.
  • However, several of the genes identified in this study, including the prolactin receptor, represent targets for further investigations on the molecular basis for histomorphological and clinical behavioral differences between acinar and ductal adenocarcinomas.

  • [Title] Differential expression of topoisomerase IIalpha protein in salivary gland carcinomas: histogenetic and prognostic implications.
  • BACKGROUND: Salivary gland carcinomas are relatively uncommon heterogeneous malignancies characterized by locoregional invasion and distant metastasis.
  • Topoisomerase IIalpha (topoIIalpha), located at chromosome 17q21-22, is considered a major mediator of cell proliferation and DNA replication.
  • The purpose of this study was to evaluate the expression of topoIIalpha in various types of salivary gland tumors and its biological significance.
  • METHODS: The protein expression of topoIIalpha was evaluated immunohistochemically in formalin-fixed, paraffin-embedded tissue from 54 salivary gland carcinomas and 20 benign tumors (10 pleomorphic adenomas and 10 Warthin's tumors).
  • The primary salivary gland carcinoma specimens consisted of 17 adenoid cystic carcinomas, 7 adenocarcinomas not otherwise specified, 7 mucoepidermoid carcinomas, 6 salivary duct carcinomas, 3 acinic cell carcinomas, 3 carcinomas ex pleomorphic adenomas, 3 epithelial-myoepithelial carcinomas, 2 carcinosarcomas, 2 lymphoepithelial carcinomas, 2 myoepithelial carcinomas, 1 oncocytic carcinoma, and 1 squamous cell carcinoma.
  • RESULTS: Of the 54 primary salivary gland carcinomas, 38 (70%) showed positive expression (> or = 10%) of topoIIalpha protein, and 16 carcinomas (30%) and all benign tumors were negative (p < 0.001).
  • Expression of topoIIalpha was more frequently observed in salivary duct carcinoma, carcinoma ex pleomorphic adenoma, adenocarcinoma, and adenoid cystic carcinoma, solid type, and it was associated with advanced stage and shortened survival.
  • Furthermore, it may provide useful prognostic information and suggests the potential efficacy of topoIIalpha-targeting therapy in patients with salivary gland carcinoma.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • BACKGROUND: Oncocytic lipoadenoma is an uncommon benign salivary gland tumor.
  • CASE: A 50-year-old woman presented with a slow-growing swelling in the left parotid region that was clinically interpreted as a soft tissue tumor, with a differential of neurofibroma/lipoma.
  • The adipose tissue background of the cytologic smears was ignored as material derived from the normal fat tissue; based on the oncocytic population of cells, a diagnosis of oncocytoma was considered.
  • A remote possibility of acinic cell carcinoma with oncocytic features was also suggested.
  • However, histopathologic examination showed it to be an oncocytic lipoadenoma, a tumor we were unaware of at the time of cytodiagnosis.
  • The clinicocytopathologic correlation highlighted in our case will be useful for cytopathologists in preoperative interpretation and diagnosis.

  • [Title] Acinar cell carcinoma of the pancreas in the United States: prognostic factors and comparison to ductal adenocarcinoma.
  • INTRODUCTION: Pancreatic acinar cell carcinoma (ACC) is a rare tumor with poorly defined prognosis.
  • OBJECTIVE: Our objective was to compare a large population of patients with ACC to pancreatic ductal cell adenocarcinoma (DCC) in order to determine distinguishing characteristics and to assess survival.
  • RESULTS: Median tumor size was 6.9 cm (vs. 4.6 cm DCC); 32.1% had nodal metastases (vs. 48.0% DCC); and 47% had high-grade tumors (vs. 37.3% DCC).
  • Patients with ACC were more likely to be male, white, and have larger tumor size, no nodal involvement, or pancreatic tail tumors.
  • On multivariable analysis, age < 65, well-differentiated tumors, and negative resection margins were independent prognostic factors for ACC.

  • [Title] Any proportion of ductal adenocarcinoma in radical prostatectomy specimens predicts extraprostatic extension.
  • Ductal adenocarcinoma of the prostate is an aggressive malignancy, often presenting at an advanced stage.
  • In mixed ductal and acinar adenocarcinomas, the relationship between the proportion of the ductal component of the tumor and the pathologic stage and whether or not aggressive behavior is simply a function of grade remains undetermined.
  • From 268 consecutive radical prostatectomies undertaken as a curative procedure for clinical localized prostate cancer, we identified 34 cases (12.7%) with ductal adenocarcinoma of the prostate comprising 5% to 100% of the total tumor volume.
  • For cases with a ductal adenocarcinoma of the prostate component, the mean age at diagnosis of 60 years (range 49-69 years), mean serum prostate-specific antigen of 8.4 ng/mL (range, 0.8-21 ng/mL) and positive surgical margin rate of 17.6% did not differ significantly from that of the pure adenocarcinoma group.
  • All 34 patients with ductal adenocarcinoma of the prostate had peripheral zone involvement while 16 (46%) also had transition zone involvement.
  • Twenty-five (73%) cases with ductal adenocarcinoma of the prostate had extraprostatic extension (pT3), which compared to 32.9% with acinar adenocarcinoma.
  • The presence of ductal adenocarcinoma of the prostate (P < .0001), high tumor volume (P = .001) and Gleason score >7 (P = .04) significantly predicted pT3 staging category, and the presence of ductal adenocarcinoma of the prostate remained a significant predictor for pT3, after adjusting for tumor volume and Gleason score >7.
  • The proportion of ductal adenocarcinoma of the prostate did not significantly modify the strength of the observed association with pathological stage.
  • In view of the significant association with extraprostatic extension we would recommend that in both core biopsies and radical prostatectomy specimens any proportion of ductal adenocarcinoma of the prostate should be reported.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • AIM: To determine whether DNA ploidy by image cytometry is a good diagnostic tool to distinguish benign and malignant salivary gland tumours.
  • According to the World Health Organization (WHO) classification, there were 14 mucoepidermoid carcinomas (MEC), 11 adenoid cystic carcinomas (ACC), 10 pleomorphic adenomas (PA), 10 carcinoma ex PA (CEPA), 9 acinic cell carcinomas (ACCa), 3 polymorphous low-grade adenocarcinomas (PLGA), 2 papillary cystadenocarcinomas (PC), 1 myoepithelial carcinoma (MC), 1 undifferentiated carcinoma (UC) and 1 mucinous adenocarcinoma (MA).
  • Paraffin sections (40 microm) were micro-dissected to isolate tumour areas; cell nuclei were extracted and Feulgen-stained cytospin monolayers were analysed using a DNA image cytometry system.
  • High-grade malignancies may be aneuploid, and ploidy may be useful to identify malignant change in atypical PA.

  • METHODS: We present a case of ACC associated with chronic calcifying pancreatitis, and a review of the literature focusing on diagnosis and management.
  • CONCLUSIONS: The clinical presentation of ACC of the pancreas is not specific and the tumor can be under-diagnosed when associated with chronic pancreatitis.
  • Data regarding course, treatment, and prognosis of this tumor are generally lacking.

  • OBJECTIVES: The aim of this study is to review salivary tumors arising from heterotopic salivary inclusions in the periparotid and cervical lymph nodal tissues over a 25-year span.
  • METHODS: A retrospective chart review revealed 24 patients with asymptomatic neck masses treated between 1976 and 2001, whose pathology demonstrated heterotopic salivary tissue or neoplasms arising from heterotopic salivary tissue.
  • RESULTS: Nine cases were benign periparotid lymph nodes with heterotopic salivary inclusions, 3 of which had multimodal involvement.
  • Fifteen cases of heterotopic salivary tumors were identified.
  • The benign tumors were predominantly Warthin's tumor (8) with 1 pleomorphic adenoma.
  • Malignant tumors included mucoepidermoid (3), acinic cell (2), and adenocarcinoma (1).
  • Among the 15 tumor patients, follow-up ranged from 1 month to 17 years.
  • Nine patients are alive and disease-free, 5 are deceased, and 1 was lost to follow-up.
  • Tumorigenic changes arise from heterotopic nodal inclusions, and although infrequent, should be considered in the differential diagnosis for isolated neck/periparotid masses and parotid Warthin's tumor.
  • Isolated low-grade malignant lesions/benign lesions are adequately managed by excision or parotidectomy alone.
  • High-grade malignant lesions require more extended surgery with possible irradiation.

  • [Title] Primary acinar cell carcinoma of the ampulla of Vater.
  • Acinar cell carcinoma of the pancreatobiliary system is a relatively rare malignant neoplasm arising usually in the pancreatic parenchyma.
  • The patient underwent a curative surgical operation, and histopathological examination revealed that the tumor was confined to the ampulla of Vater with no continuity to the pancreatic parenchyma.
  • The tumor cells showed acinar or tubular arrangement with eosinophilic to basophilic granular cytoplasm, findings identical to those of acinar cell carcinoma of the pancreas.
  • Immunohistochemically, the tumor cells were positive for lipase.
  • From these findings, we concluded that the tumor was primary acinar cell carcinoma arising in the ampulla of Vater, probably originating from heterotopic pancreatic tissue.
  • This is the first reported case of primary acinar cell carcinoma in the ampulla of Vater.

  • [Title] Analysis of acinic cell carcinoma of the parotid gland - 15 years experience.
  • CONCLUSION: In our experience, the prognosis for parotid gland acinic cell carcinoma (AciCC) is good.
  • Surgery alone would be sufficient in early-stage tumor.
  • Postoperative adjuvant treatment in advanced-stage patients or those with positive resection margins usually gives satisfactory control of the disease.
  • OBJECTIVES: AciCC is a rare tumor in parotid gland malignancy.
  • RESULTS: Thirteen male and 12 female patients ranged in age from 16 to 84 years (mean 37.5 years) at the time of diagnosis.
  • The tumor stage distributions of the patients were 24%, 44%, 28%, and 4% for stages I, II, III, and IV, respectively.
  • The 10-year disease-free and overall actuarial survivals were both 84% in a mean follow-up of 75.8 months.

  • [Title] AgNOR count and subjective AgNOR pattern assessment (SAPA) score in carcinoma of the pancreatic head including periampullary tumors.
  • CONTEXT: Only a few studies are available in the literature regarding the AgNOR (argyrophilic nucleolar organizer region) count in pancreatic adenocarcinoma but studies on the SAPA (subjective AgNOR pattern assessment) score are completely lacking.
  • OBJECTIVE: We attempted to estimate the AgNOR count and the SAPA score in carcinoma of the pancreatic head including periampullary tumors and to correlate them with other various clinico-histological parameters.
  • PATIENTS: Twenty-four cases of carcinoma of the pancreatic head including periampullary tumors.
  • MAIN OUTCOME MEASURES: Patients were studied for the AgNOR count and the SAPA score, and the values were correlated with the size of the tumor, the type of tumor and histological type and grade of tumor.
  • The AgNOR count was 1.6+/-0.1 in the healthy pancreas while it was 2.8+/-0.5 in cases of pancreatic carcinoma (P<0.001).
  • The SAPA score was 5.6+/-0.2 in the healthy pancreas while it was 8.0+/-1.4 in pancreatic carcinoma (P<0.001).
  • Tumors less than or equal to 2 cm in size had an AgNOR count of 2.6+/-0.08 while the AgNOR count was 3.4+/-0.02 in tumors larger than 2 cm (P<0.001).
  • The SAPA score was also higher in tumors greater than 2 cm in size (7.3+/-0.2 vs. 9.4+/-0.8; P<0.001).
  • Periampullary tumors had a significantly lower (P<0.001) AgNOR count (2.7+/-0.06) and SAPA score (7.8+/-0.2) as compared to carcinoma of the head of the pancreas (AgNOR count 3.3+/-0.03 and SAPA score 9.2+/-0.7).
  • Well-differentiated carcinomas had significantly lower AgNOR counts as compared to other tumors except acinar cell carcinomas since acinar cell carcinomas are also well-differentiated tumors.
  • The SAPA score was also higher in moderately-differentiated tumors and the difference between moderately-differentiated tumor and other types of tumors was significant although there was no significant difference between cystadenocarcinomas and unclassified tumors, and between acinar cell carcinomas and well-differentiated tumors on SAPA scoring.
  • CONCLUSIONS: The values of the AgNOR count and the SAPA score are well-correlated with the size of the tumor, the type of tumor and the histological grade.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Two cases of 18 F-FDG PET/CT findings in acinar cell carcinoma of the pancreas.
  • The patients consisted of a 60-year-old woman and a 72-year-old man with no significant symptoms, who were both referred to the hospital due to the presence of large pancreatic tumors.
  • They underwent F-18 FDG PET/CT and subsequently a pancreaticoduodenectomy and acinar cell carcinoma in the pancreas was proven histopathologically.
  • In one case, the tumor consisted of a solid component presenting intense FDG uptake and necrotic tissue.
  • In another case, the tumor consisted of cystic and papillary components presenting with weak FDG uptake.
  • This report thus documents 2 cases of acinar cell carcinoma that showed contrasting histopathologic and F-18 FDG PET/CT findings.

  • [Title] Lymphoepithelioma-like carcinoma of the prostate.
  • In this report, we summarized the clinicopathologic features of 5 cases of lymphoepithelioma-like carcinoma of the prostate, a rare variant of prostate cancer characterized by a malignant epithelial component densely infiltrated by lymphoid cells.
  • The initial diagnosis of lymphoepithelioma-like carcinoma of the prostate was made on transurethral resection in 3 cases and radical prostatectomy in 2 others.
  • In one case the diagnosis of lymphoepithelioma-like carcinoma admixed with conventional acinar adenocarcinoma was an unexpected finding at time of transurethral resection for benign prostatic hyperplasia.
  • Three patients had clinical stage T3 tumors and another had stage T4 disease; stage T1b was present in the remaining case.
  • Microscopically, all tumors contained lymphoepithelioma-like carcinoma, which comprised 10% to 90% of the entire tumor.
  • All cases were associated with adenocarcinoma, either as the sole pattern in 5 cases or with an additional ductal component in 3 cases.
  • One case had additional features of adenosquamous carcinoma.
  • The lymphoepithelioma-like carcinoma component was characterized by indistinct cytoplasmic borders and a syncytial growth pattern.
  • Immunohistochemical staining demonstrated that lymphoepithelioma-like carcinoma was positive for prostate-specific antigen, prostate acid phosphatase, alpha-methylacyl coenzyme A racemase, and epithelial membrane antigen; several cytokeratins (AE1/AE3, 7, 8, and 20 [rare cells]) were also immunoreactive.
  • Latent membrane protein 1 immunostaining and in situ hybridization for Epstein-Barr virus were negative in all 5 lymphoepithelioma-like carcinoma cases.
  • DNA ploidy of lymphoepithelioma-like carcinoma tumors gave DNA histograms with aneuploid peaks.
  • DNA ploidy of the concurrent adenocarcinoma gave DNA aneuploid peaks except in one DNA diploid case.
  • Four patients died of disease from 8 to 26 months; one patient was lost to follow-up.
  • In summary, lymphoepithelioma-like carcinoma of the prostate arise in aggressive prostate cancers at advanced clinical stage.
  • Morphologic recognition and distinction from other prostatic lesions and tumors with prominent lymphoid stroma is critical for its clinical management.

  • [Title] High expression level of geminin predicts a poor clinical outcome in salivary gland carcinomas.
  • AIMS: To examine the prognostic impact of geminin expression, a negative regulator of DNA replication, in salivary gland carcinomas.
  • METHODS AND RESULTS: Tissues from 170 patients with salivary gland carcinoma were assembled in a tissue microarray format, and immunohistochemistry staining for geminin and Ki67 was performed.
  • The LI for geminin was relatively low in acinic cell carcinoma (mean 1.55%) and mucoepidermoid carcinoma (mean 2.43%), intermediate in adenoid cystic carcinoma (mean 4.09%), and relatively high in salivary duct carcinoma (mean 15.22%).
  • The increased expression of geminin was more strongly associated with reduced overall and relapse-free survival rates than with Ki67 expression and was a significant and independent prognostic factor in patient survival and tumour relapse.
  • CONCLUSIONS: Geminin expression is potentially a useful marker for predicting tumour aggressiveness and clinical outcome in salivary gland carcinomas.

  • For each Gleason pattern exist a number of benign and malignant mimickers that can simulate prostatic adenocarcinoma.
  • In the present review, the use of immunohistochemical markers is discussed with emphasis to a pattern-based approach to differential diagnosis in prostate pathology.
  • Basal cell markers (34betaE12 and P63) are very useful to analyze histo-architectural features of small and large glandular lesions.
  • AMACR (P504 s) is helpful not only in identifying small amount of cancer in needle biopsies but also in the diagnosis of high grade prostatic intra epithelial neoplasia (HGPIN).
  • A number of lesions which may be confused with small acinar adenocarcinoma (Cowper's gland, nephrogenic metaplasia, mesonephric glands) and poorly differentiated prostate cancer (urothelial neoplasia, mucinous colon cancer and other metastatic lesions) lacks convincing PSA immunoreactivity.

  • These records and slides were reviewed to identify cytologic characteristics that contributed to false diagnosis.
  • RESULTS: Of a total of 1,040 salivary FNA samples, 376 cases had a final histologic diagnosis with interpretations of benign or malignant.
  • The sensitivity and specificity for correct interpretation of benign and malignant were 87% and 96%, respectively.
  • The most common false negative cases were acinic cell carcinoma, epithelial myoepithelial carcinoma, adenoid cystic carcinoma and basal cell adenocarcinoma.
  • Benign cases with false positive diagnosis were Warthin tumor and pleomorphic adenoma.
  • CONCLUSION: Knowledge of cytologic overlaps and pitfalls on salivary gland FNA, as well as clinical and radiologic features, may help clinicians arrive at the appropriate diagnosis and reduce false interpretations.
  • Several clinically important pitfalls with nonsalivary tumors of jaw and skin are demonstrated in our series.

  • There are some unusual histologic variants of prostate carcinoma, including mucinous, signet-ring cells, and ductal carcinomas that can metastasize in a problematic way and simulate lung, colorectal, or bladder primaries.
  • Our aim is to study the profile of expression of Cdx2, thyroid transcription factor 1 (TTF1), and cytokeratin 20 (CK20) in prostate cancer with unusual histologic finding.
  • Twenty-nine prostate adenocarcinomas with unusual histologic findings were submitted to immunohistochemistry with prostate-specific antigen (PSA), CK20, Cdx2, and TTF1 antibodies.
  • There were 7 mucinous, 5 ductal, 2 signet-ring cells, and 15 usual acinar adenocarcinomas with focal mucinous differentiation.
  • To compare the results with usual acinar adenocarcinomas, we studied 10 primary and their respective lymph node metastases in a tissue microarray, 2 unusual metastatic adenocarcinomas, and 6 usual acinar high-grade carcinomas.
  • For tumors with special histologic finding, Cdx2 was expressed by 9 (31.0%) mucinous, signet-cell, or with focal mucinous differentiation.
  • Thyroid transcription factor 1 was moderately positive in mucinous differentiation areas of 2 (6.9%) adenocarcinomas.
  • Cytokeratin 20 was expressed by 9 (31.0%) tumors, among them, 3 ductal adenocarcinomas.
  • Prostate-specific antigen was positive in 28 (96.6%) cases and negative in 1 ductal adenocarcinoma.
  • There was only 1 worrisome ductal adenocarcinoma that was strongly CK20 positive and PSA negative.
  • Almost one third of mucinous prostate carcinomas express Cdx2.
  • Cytokeratin 20 can be positive also in one third of prostate carcinomas, especially the ductal type.

  • [Title] Subepithelial myofibroblast in lung adenocarcinoma: a histological indicator of excellent prognosis.
  • We report here the presence of subepithelial myofibroblasts in pure bronchioloalveolar carcinoma and a subset of invasive lung adenocarcinoma.
  • To gain insight into their biological significance, we examined 116 surgically resected lung adenocarcinomas.
  • The resected tumors included 13 bronchioloalveolar carcinomas, 20 mixed type adenocarcinomas with bronchioloalveolar carcinoma components, 57 papillary adenocarcinomas, 22 solid adenocarcinomas with mucin, and 4 acinar adenocarcinomas.
  • In all of the pure bronchioloalveolar carcinomas observed, the subepithelial myofibroblasts were completely preserved adjacent to the cancer cells.
  • In mixed adenocarcinomas with bronchioloalveolar carcinoma components, subepithelial myofibroblasts were present in the bronchioloalveolar carcinoma components, but scanty in the invasive areas, where stromal myofibroblasts emerged between the cancer cell nests.
  • Subepithelial myofibroblasts were retained, however, in the invasive areas of a subset of invasive adenocarcinomas.
  • Survival analysis showed that the retention of subepithelial myofibroblasts in these invasive tumors was associated with low rates of lymphatic and vascular invasion, a low rate of lymph node involvement, and an excellent patient survival.
  • These results suggest that subepithelial myofibroblasts increase in bronchioloalveolar carcinomas, but are gradually replaced by typical stromal myofibroblasts during progression into invasive cancer.
  • A subset of invasive adenocarcinomas retains subepithelial myofibroblasts.
  • Analysis of subepithelial myofibroblasts may be helpful in identifying a subset of lung adenocarcinoma with excellent prognosis.

  • [Title] Pancreatic ducts as an important route of tumor extension for acinar cell carcinoma of the pancreas.
  • Acinar cell carcinoma (ACC) of the pancreas is very rare, which usually grows expansively.
  • We reviewed the detailed gross and histologic features of 13 cases of ACC, of which 7 (54%) showed intraductal polypoid growth (IPG) of the tumor in the large pancreatic ducts with a mean IPG length of 24.8 mm.
  • Tumors with IPG were found to spread characteristically along the pancreatic ducts as extending polypoid projections, filling the ducts and destroying the duct walls, although tumors did not tend to extend beyond the pancreatic parenchyma.
  • Comparison of the clinicopathologic characteristics showed that ACC with IPG had less infiltrative features including lymphatic, venous, and neural invasion, formation of tumor thrombus in the portal vein, nodal metastasis, and invasion beyond the pancreas to the surrounding organs; death in only 1 case (14%) of ACC with IPG was the result of ACC itself.
  • In contrast, ACC without IPG frequently showed more infiltrative growth, and was the cause of death in 50% of patients with this type of tumor.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] From Krukenberg to today: the ever present problems posed by metastatic tumors in the ovary. Part II.
  • This is the second of a two-part consideration of metastatic tumors to the ovary.
  • The first tumor discussed is gastric carcinoma of intestinal-type whose ovarian manifestations have been the subject of a recent paper which emphasized its differences from the Krukenberg tumor.
  • Coverage of intestinal adenocarcinoma emphasizes the landmark 1987 paper of RH Lash and WR Hart.
  • The section on pancreatic neoplasms reemphasizes the problems caused by metastatic ductal carcinoma, considered primarily in Part I, and discusses less common issues such as spread of neuroendocrine and acinar cell carcinomas.
  • The limited information on spread of tumors of the gallbladder and extrahepatic bile ducts is then reviewed before more detailed consideration of hepatic neoplasms, prompted by recent contributions on hepatocellular carcinoma and intrahepatic cholangiocarcinoma, the latter based on significant experience with this problem in Thailand.
  • The section on appendiceal neoplasms highlights ovarian spread of diverse tumors ranging from typical intestinal-type adenocarcinoma to signet-ring cell carcinomas with various patterns which in the ovary may prompt diagnoses such as a goblet cell (mucinous) carcinoid tumor, but whose ovarian features place them in the category of a Krukenberg tumor.
  • The diverse problems in differential diagnosis of carcinoid tumor (provoked by nested, acinar, and other patterns, including folliclelike spaces) are then reviewed.
  • The section on breast cancer emphasizes that, although usually a manifestation of late stage disease and often not bulky in the ovaries, metastatic breast cancer may form large masses which can represent the clinical presentation.
  • The section on lung tumors largely reflects information in a recent paper that small cell carcinoma and adenocarcinoma are the lung cancers that spread to the ovary most commonly.
  • The extremely broad differential diagnosis posed by metastatic malignant melanoma ranging from that of an oxyphilic tumor, to a small cell tumor, to a follicle-forming neoplasm, is then considered.
  • The sections on renal cell carcinoma and other urinary tract neoplasms emphasize the differential diagnosis of metastatic clear cell carcinoma and primary clear cell carcinoma, an issue usually resolvable by an awareness of the various features of the ovarian variant, rarely or never seen in the renal variant.
  • The section on metastatic sarcomas discusses endometrial stromal sarcomas, gastrointestinal stromal neoplasms, and miscellaneous other sarcomas.
  • The endometrial stromal tumors are problematic largely because the history of a primary tumor may be remote, in the ovaries the typical growth and vascular pattern of endometrial stromal neoplasms is not always conspicuous, and some endometrial stromal sarcomas in the ovary show sex cordlike patterns of growth.
  • Recent information has indicated that gastrointestinal stromal tumors may rarely have significant ovarian manifestations and if the primary neoplasm is overlooked, the ovarian tumor may be misdiagnosed, usually as an ovarian fibromatous tumor, but potentially as another primary neoplasm.
  • The sections on ovarian spread of uterine carcinomas emphasize the problems owing to cervical adenocarcinomas, which have a greater tendency to involve the ovaries than squamous cell carcinomas and can simulate primary mucinous or endometrioid cancers.
  • The final neoplasms considered are malignant mesothelioma and the desmoplastic small round cell tumor.
  • The microscopic features of malignant mesothelioma are so different from those of primary ovarian carcinoma in most instances that the diagnosis should be readily established on routine microscopic evaluation.
  • The differential diagnosis of the desmoplastic small round cell tumor is more complex because of the greater overlap with the many other small cell malignant tumors that may involve the ovaries primarily or secondarily.
  • Nonetheless, differences exist in most cases and awareness of the entity should lead to consideration of the desmoplastic neoplasm, particularly in a young female.
  • However, as pointed out in brief concluding remarks, despite the aid of that modality, as in surgical pathology overall, careful consideration of the clinical background, distribution of disease, gross characteristics and spectrum of routine microscopic findings, will lead to the correct diagnosis in the majority of cases and at the very least lead to formulation of a considered differential diagnosis such that use of special techniques may be judicious and those results placed in context of the time-honored clinical and pathologic features.

  • [Title] [Correlation of early phase contrast enhancement of multi-detector row computed tomography to tumor stroma of nodular solid lung adenocarcinoma].
  • BACKGROUND & OBJECTIVE: Dynamic enhanced multi-detector row CT (MDCT) has been used in differential diagnosis of pulmonary nodules, but its mechanism was unclear yet.
  • This study was to evaluate the correlations of early phase enhancement of MDCT to proportion and distribution of stroma in solid lung adenocarcinoma.
  • METHODS: A total of 31 patients with lung adenocarcinoma underwent routine contrast-enhanced MDCT.
  • Tumor morphology was observed with HE staining.
  • RESULTS: The proportion of invasive stroma in tumors was correlated positively to CT enhancement value (r=0.483, P=0.006).
  • Most acinar adenocarcinomas had net enhancement of > 20 Hu, which was significantly higher than that of solid adenocarcinomas with mucin subtype (P=0.005).
  • CONCLUSIONS: Extent and pattern of CT enhancement of solid lung adenocarcinoma nodules reflect the proliferation and distribution of stroma, respectively.
  • It is helpful to comprehend some false negative on CT enhancement by adequately understanding of the pathologic features of different subtypes of lung adenocarcinoma.

  • [Title] Local-regional recurrence after surgery without postoperative irradiation for carcinomas of the major salivary glands: implications for adjuvant therapy.
  • PURPOSE: To determine factors predictive of local-regional recurrence (LRR) after surgery alone for carcinomas of the major salivary glands in an attempt to evaluate the potential role of postoperative radiation therapy.
  • METHODS AND MATERIALS: Between 1960 and 2004, 207 patients with carcinomas of the major salivary glands were treated with definitive surgery without postoperative radiation therapy.
  • Histology was: 67 mucoepidermoid (32%), 50 adenoid cystic (24%), 34 acinic cell (16%), 23 malignant mixed (11%), 16 adenocarcinoma (8%), 6 oncocytic (3%), 6 myoepithelial (3%), and 5 other (2%).
  • A Cox proportional hazard model identified pathologic lymph node metastasis (hazard ratio [HR], 4.8; p = 0.001), high histologic grade (HR, 4.2; p = 0.003), positive margins (HR, 2.6; p = 0.03), and T3-4 disease (HR, 2.0; p = 0.04) as independent predictors of LRR.
  • CONCLUSION: Lymph node metastasis, high tumor grade, positive margins, and T3-4 stage predict for significant rates of LRR after surgery for carcinomas of the major salivary glands.
  • Postoperative radiation therapy should be considered for patients with these disease characteristics.

  • [Title] [Pathologic characteristics of pseudohyperplastic prostatic adenocarcinoma].
  • OBJECTIVE: To study the clinicopathologic features of 30 cases of pseudohyperplastic prostatic adenocarcinoma (PHPA).
  • The incidence, morphology, pathologic differential diagnosis, tumor volume, preferred location and Gleason's score were studied.
  • Histologically, 66.7% of PHPA demonstrated direct transition with conventional acinar adenocarcinoma; and 76.7% of cases had coexisting conventional acinar adenocarcinoma in the remaining tissue blocks.
  • The tumor volume accounted for 5% to 100% of total carcinoma among core needle biopsy and 1% to 30% of total carcinoma among radical prostatectomy.
  • PHPA resembled benign prostate glands, in which the hyperplastic malignant acini were predominantly of medium to large size.
  • Although PHPA looked benign morphologically, 66.7% cases had stromal invasion, 6.7% had perineural invasion and 3.3% had bone metastasis.
  • The tumor was primarily located in the peripheral zone.
  • CONCLUSIONS: PHPA is not a rare phenomenon in prostatic adenocarcinoma.
  • Majority of cases have concurrent conventional acinar adenocarcinoma.
  • It is different from well-differentiated (with Gleason's score 1 or 2) adenocarcinoma with a relatively indolent clinical course.
  • In contrast, PHPA corresponds to moderately differentiated adenocarcinoma with Gleason's score of 3.

  • [Title] Pure acinic cell carcinoma of the breast in an 80-year-old Japanese woman.
  • Acinic cell carcinoma of the breast is an uncommon neoplasm.
  • Since the first case of this rare variant of breast carcinoma was reported in 1996, only 10 cases have been reported in the English-language literature.
  • Reported herein is the first case of primary acinic cell carcinoma of the breast in a Japanese woman.
  • To the naked eye, the tumor appeared well circumscribed and the cut surface was grayish-pink and hemorrhaging.
  • Microscopically, the tumor was predominantly made up of a monotonous proliferation of cells with a finely granular cytoplasm, resembling acinic cells of the parotid gland.
  • In spite of extensive sampling, no common histological patterns of breast carcinoma such as in situ and invasive ductal carcinoma were recognized in the present case, indicating that the present case was pure acinic cell carcinoma.
  • In addition, the immunohistochemical profile of this tumor was identical to that of the acinic cell carcinoma of the salivary gland: estrogen receptor, progesterone receptor, HER2 and cytokeratin (CK)20 were negative and amylase and CK7 were positive.
  • The patient has been well for 22 months since the wide local excision of the tumor and no signs of salivary neoplasm are evident to date.

  • A study of 701 primary adenocarcinomas of the lung was made at the Department of Pathology of the Hospital da Universidade de Coimbra for a period of fifteen years, between 1990 and 2004.
  • The incidence of primary adenocarcinomas varied from 16 cases in 1990 to 49 cases in men and from 12 to 37 cases in women in that period.
  • In the last four years, since 2001, patients were in the seventies at the time of diagnosis and a considerable number of cases were diagnosed after 80 years of age.
  • The criteria defined by the WHO classification of Tumours of the Lung, Pleura, Thymus and Heart 2004 were applied to the primary adenocarcinomas of the lung and as was expected, bronchioloalveolar carcinomas had its incidence in women while acinar adenocarcinomas were diagnosed mainly in men.
  • A number of 109 cases had the final diagnosis of adenocarcinoma of the lung based on morphology and immunohistochemistry criteria.

  • [Title] [Endoscopic resection of benign and malignant tumors in the nasal cavity and paranasal sinus].
  • Endoscopic resection of nasal and paranasal sinus tumors is more aesthetic and less invasive than conventional resection, such as Luc's operation and lateral rhinotomy.
  • We clarified the effect of radical endoscopic tumor excision and the control of local bleeding hazardous in endoscopic surgery.
  • Subjects were patients with benign lesions in the nasal cavity, medial wall of the maxillary sinus, ethmoid sinus, and/or sphenoid sinus without concurrent malignant lesions.
  • Although patients selection for malignant tumor excision was based on (1) possible en bloc resection, (2) low-grade malignant tumors, and (3) tumors in the nasal cavity and adjoining paranasal sinus, the final decision was made individual.
  • Subjects were 23 patients with benign tumor (10 inverted papilloma, 9 hemangioma, 2 juvenile angiofibroma, and 2 other tumors) and 4 with malignant tumor (olfactory neuroblastoma, acinic cell carcinoma, squamous cell carcinoma, and chondroid chordoma) in the nasal and paranasal sinus.
  • The tumor was resected en bloc except for patients with inverted papilloma (2 cases) and chondroid chordoma.
  • Recurrence in benign tumors was zero during a mean observation of 21 months.
  • The endoscopic excision of benign lesions in the nasal and paranasal sinus is thus as effective as conventional radical surgery.
  • Endoscopic removal of malignant lesions remains controversial because of the small number of patients and short postoperative observation.

  • [Title] Acinar cell carcinoma of the pancreas: clinical analysis of 115 patients from Pancreatic Cancer Registry of Japan Pancreas Society.
  • OBJECTIVES: Acinar cell carcinoma (ACC) of the pancreas is a rare tumor, and many aspects remain unclear because no large-scale clinical studies have been conducted.
  • RESULTS: Although ACC has been associated with advanced stage and poor prognosis, this tumor was resectable in 76.5% of the patients, and the 5-year survival rate after resection was favorable, being 43.9%.
  • CONCLUSIONS: Confirming the diagnosis of ACC preoperatively is difficult, but this diagnosis should be kept in mind while planning surgery for ordinary pancreatic cancer.
  • Once the diagnosis has been confirmed, a possibility of surgical resection should be pursued to achieve better prognosis.

  • [Title] Abnormal expression of Rb pathway-related proteins in salivary gland acinic cell carcinoma.
  • Salivary gland acinic cell carcinoma (ACC) is a relatively rare neoplasm, and limited information is available regarding its molecular pathogenesis.
  • Because the deregulation of Rb pathway is common to most human tumors, we immunohistochemically investigated the expression of Rb pathway-related proteins, including Rb, Rb proteins phosphorylated at serine 780 and 795 (pRb-S780 and pRb-S795, respectively), cyclin D1, and p16INK4a in 18 cases of ACC.
  • The expression of topoisomerase II-alpha and Ki-67 was also examined to evaluate cell proliferation.
  • Double immunofluorescent staining demonstrated that pRb-S795 was colocalized with cyclin D1 in most tumor cells.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • METHODS: This review presents an analysis of the usefulness of FNA in differential diagnosis of parotid pathologies.
  • FNA is notoriously unreliable in recognising the malignant nature of parotid carcinoma providing its precise classification and establishing its grade.
  • A few malignant neoplasms are particularly prone to diagnostic error: acinic cell carcinoma is frequently interpreted as benign, and low-grade lymphomas are often discounted as inflammatory processes.
  • CONCLUSIONS: FNA cytology is useful in avoiding surgery (inflammatory lesions) or limiting surgical procedures (benign tumours).
  • For planning the extent of surgery of malignant parotid tumours, the histological subtype and/or grade should be determined; therefore, a histological diagnosis by frozen section analysis is required.

  • [Title] [A case of liver metastasis of pancreatic acinar cell carcinoma treated with S-1 and intra-arterial CDDP combination therapy].
  • A 55-year-old man underwent a pylorus-preserving pancreatoduodenectomy in August 2006 because of acinar cell carcinoma of the head of the pancreas.
  • At the beginning of this treatment, it seemed to be a stable disease, but CT revealed tumor progression in January 2007.
  • Despite the change to oral chemotherapy with S-1 (100 mg/body, day 1-14/q3w), tumors were markedly enlarged in March 2007.
  • After 6 months of treatment, abdominal CT revealed marked shrinkage of tumors, accompanied by a decrease in AFP level.
  • We suggest that combination chemotherapy with oral S-1 and intra-arterial CDDP can be effective treatments for pancreatic acinar cell carcinoma.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • We find in a murine model of familial pancreatic cancer that germline heterozygosity for a pathogenic Brca2 truncation suffices to promote pancreatic ductal adenocarcinomas (PDACs) driven by Kras(G12D), irrespective of Trp53 status.
  • Unexpectedly, tumor cells retain a functional Brca2 allele.
  • Three tumors from these patients displaying LOH were acinar carcinomas, which also developed only in mice with biallelic Brca2 inactivation.
  • We suggest a revised model for tumor suppression by BRCA2 with implications for the therapeutic strategy targeting BRCA2 mutant cancer cells.

  • INTRODUCTION: The presentation and outcome of patients with acinar cell carcinoma (ACC) of the pancreas compared to the more common ductal cell adenocarcinoma (DCA) may be distinct.
  • Mean tumor size was 5.3 cm.
  • American Joint Commission on Cancer tumor stages were stage I (two), stage II (eight), stage III (four), and stage IV (three).
  • This is in contrast to 1,608 patients with ductal cell adenocarcinoma who underwent resection identified from recent literature reports where the average median survival was only 24 months.
  • CONCLUSION: Acinar cell carcinoma of the pancreas is rare and appears to have a presentation and outcome distinct from the more common pancreatic DCA.

  • PURPOSE: Acinic cell carcinoma (ACC) is an infrequent type of malignant salivary gland tumor.
  • This study was undertaken to 1) report on the clinicopathologic characteristics of 21 intraoral examples, 2) reconfirm the reported indolent behavior of these tumors, and 3) verify the synchronous or metachronous occurrence of other malignancies with ACC.
  • The size of the tumors varied from 0.6 to 1.6 cm.
  • Eleven patients did not report recurrence or metastatic disease.
  • One patient had 2 recurrences due to erroneous diagnosis that led to inappropriate treatment.
  • After properly diagnosed and treated, this patient has been free of tumor for 4 years.
  • Of interest were the metachronous occurrence of lymphoma in 1 patient and the synchronous occurrence of renal cell carcinoma in another.
  • CONCLUSION: This study confirms the indolent behavior of ACC of minor salivary glands and previous reports on the occasional synchronous or metachronous association of malignant salivary gland tumors with other malignancies.

  • [Title] Acinar cell carcinoma arising from an ectopic pancreas.
  • We herein report a rare case of ectopic pancreatic acinar cell carcinoma (ACC) which presented as a submucosal tumor of the pylorus.
  • Esophago-gastroduodenal endoscopy showed no mucosal lesions, but a submucosal tumor was observed around the pylorus.
  • We diagnosed a gastrointestinal stromal tumor or malignant lymphoma preoperatively, and decided to perform an operation in order to confirm the diagnosis and select the optimal treatment.
  • The resected specimen showed the 7.6 x 4.9-cm size tumor to mainly originate from the pylorus.
  • Histopathologically, the tumor was identified as pancreatic ACC with lymph node metastasis.
  • The tumor cells were labeled by immunohistochemical staining for alpha1-antitrypsin.
  • Because of the tumor location, we considered the tumor to have originated from the ectopic pancreatic tissue in the stomach.

  • [Title] Intraductal carcinoma of the prostate without invasive carcinoma on needle biopsy: emphasis on radical prostatectomy findings.
  • PURPOSE: Limited information is available on radical prostatectomy findings in men with intraductal carcinoma of the prostate on needle core biopsy in the absence of invasive prostate cancer.
  • Of the 21 radical prostatectomies available for review findings revealed pathological stage pT3a in 8 (38%), pT3b in 3 (13%), pT2 in 8 (38%) and intraductal carcinoma without identifiable invasive cancer in 2 (10%).
  • In 15 prostatectomies (71%) there was extensive intraductal carcinoma, defined as greater than 10% of tumor being intraductal, including the 2 cases of intraductal carcinoma only.
  • Of the 19 prostatectomies with invasive adenocarcinoma 16 (84%) were conventional acinar adenocarcinoma, 2 (11%) ductal adenocarcinoma, and 1 (5%) mixed ductal and acinar adenocarcinoma.
  • CONCLUSIONS: At radical prostatectomy men in whom prior biopsies showed only intraductal carcinoma of the prostate typically have high grade (Gleason score 7 or greater) invasive adenocarcinoma and most have advanced stage disease (pT3).
  • Definitive therapy is recommended in men with intraductal carcinoma of the prostate on needle biopsy even in the absence of pathologically documented invasive prostate cancer.

  • [Title] Sarcomatoid carcinoma of the prostate: a study of 42 cases.
  • Sarcomatoid carcinoma of the prostate is a rare type of prostatic cancer.
  • With the exception of 1 study, the morphologic features and patient outcomes have been reported only in relatively small case series and individual reports.
  • We examined transurethral resection, needle biopsy, and radical prostatectomy specimens from 42 patients with sarcomatoid carcinoma of the prostate, all of which were received in consultation.
  • Prior prostatic adenocarcinoma: The majority of patients (n=21; 66%) had a prior history of acinar adenocarcinoma of the prostate.
  • Of the remaining patients for whom this information was known, 11 patients presented with de novo sarcomatoid carcinoma.
  • The time between the original diagnosis of acinar adenocarcinoma and diagnosis of sarcomatoid carcinoma ranged from 6 months to 16 years (mean 6.8 y).
  • Concurrent adenocarcinoma: The majority of patients demonstrated a concurrent high grade acinar carcinoma of Gleason score 7 (n=3), 8 (n=9), 9 (n=10), and 10 (n=10).
  • A subset of patients contained an admixed ductal adenocarcinoma (n=4), small cell carcinoma (n=3), squamous cell carcinoma (n=3), or other unusual pattern of prostate carcinoma (n=3).
  • In 1 case, the diagnosis was based on immunohistochemical evidence of epithelial differentiation along with the history of prior adenocarcinoma.
  • PROGNOSIS: approximately half of all patients developed metastatic disease either at time of presentation or subsequently.
  • Of patients with meaningful follow-up, 6/7 died within 1 year of the diagnosis of sarcomatoid carcinoma; 20 were alive yet with very short follow-up (median 1 y; mean 2.3 y).
  • Kaplan-Meier analysis revealed that the actuarial risk of death at 1 year after diagnosis of sarcomatoid carcinoma was 20%.
  • No correlation was identified between patient survival and morphologic features, before radiation or hormone therapy, or concurrent high-grade prostate cancer.
  • Sarcomatoid carcinoma demonstrates diverse spindle and epithelial cell morphologies.
  • The epithelial component is typically high-grade acinar adenocarcinoma, yet other aggressive tumor subtypes such as ductal adenocarcinoma and small cell carcinoma may also be seen.
  • Sarcomatoid carcinoma is an aggressive form of prostate cancer, the prognosis of which is dismal regardless of other histologic or clinical findings.

  • [Title] Loss of Maspin expression is a negative prognostic factor in common salivary gland tumors.
  • Maspin, a 42kDa protein, belongs to the serine protease inhibitor (serpin) family and is suggested to have inhibitory effects on tumor-induced angiogenesis, tumor cell motility, invasion and metastasis and influences prognosis of tumor patients.
  • High proportions of Maspin expression were observed in adenoid cystic carcinomas, mucoepidermoid carcinomas and carcinomas ex pleomorphic adenoma, low proportions were seen in salivary duct carcinomas.
  • Acinic cell carcinomas did not show any Maspin expression.
  • Analysis of the prognostic impact of Maspin expression was restricted to salivary gland carcinoma types of intermediate malignancy grade (adenoid cystic carcinoma, mucoepidermoid carcinoma and carcinoma ex pleomorphic adenoma).
  • For these tumors, univariate analyses revealed that T-stage (p=0.025), age70 (p=0.0065), loss of Maspin (p=0.0016) and presence of residual tumor (p<0.001) correlated with poor prognosis.
  • Moreover, negative Maspin staining was associated with lymph node metastasis and residual tumor.
  • According to these findings, Maspin might be useful as a new prognostic marker in adenoid cystic carcinoma and in salivary gland carcinomas with intermediate grade of malignancy where grading systems are still under debate.
