  • [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] Combined immunohistochemistry of beta-catenin, cytokeratin 7, and cytokeratin 20 is useful in discriminating primary lung adenocarcinomas from metastatic colorectal cancer.
  • However, often, the discriminating diagnosis of primary lung acinar adenocarcinoma and lung metastasis of colorectal cancer based on morphological and pathological findings is difficult.
  • The purpose of this study was to evaluate the clinical usefulness of immunohistochemistry of beta-catenin, cytokeratin (CK) 7, and CK20 for the discriminating diagnosis of lung cancer.
  • METHODS: We performed immunohistochemistry of beta-catenin, CK7, and CK20 in 19 lung metastasis of colorectal cancer samples, 10 corresponding primary colorectal cancer samples and 11 primary lung acinar adenocarcinoma samples and compared the levels of accuracy of the discriminating diagnosis by using antibodies against these antigens.
  • RESULTS: Positive staining of beta-catenin was observed in all the lung metastasis of colorectal cancer samples as well as in the primary colorectal cancer samples but in none of the primary lung acinar adenocarcinoma samples.
  • Positive staining of CK7 was observed in 90.9% of the primary lung acinar adenocarcinoma samples and in 5.3% of the lung metastasis of colorectal cancer samples, but in none of the primary colorectal cancer samples.
  • Positive staining of CK20 was observed in all the primary colorectal cancer samples and in 84.2% of the lung metastasis of colorectal cancer samples, but in none of the primary lung acinar adenocarcinoma samples.
  • CONCLUSION: Combined immunohistochemistry of beta-catenin, CK7, and CK20 is useful for making a discriminating diagnosis between lung metastasis of colorectal cancer and primary lung acinar adenocarcinoma.
  • This method will enable accurate diagnosis of a lung tumor and will be useful for selecting appropriate therapeutic strategies, including chemotherapeutic agents and operation methods.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] TMPRSS2-ERG gene fusions are infrequent in prostatic ductal adenocarcinomas.
  • Ductal adenocarcinoma of the prostate is an unusual subtype that may be associated with a more aggressive clinical course, and is less responsive to conventional therapies than the more common prostatic acinar adenocarcinoma.
  • However, given its frequent association with an acinar component at prostatectomy, some have challenged the concept of prostatic ductal adenocarcinoma as a distinct clinicopathologic entity.
  • We studied the occurrence of the TMPRSS2-ERG gene fusion, in 40 surgically resected ductal adenocarcinoma cases, and in their associated acinar component using fluorescence in situ hybridization.
  • A group of 38 'pure' acinar adenocarcinoma cases matched with the ductal adenocarcinoma group for pathological grade and stage was studied as a control.
  • Compared with the matched acinar adenocarcinoma cases, the TMPRSS2-ERG gene fusion was significantly less frequently observed in ductal adenocarcinoma (45 vs 11% of cases, P=0.002, Fisher's exact test).
  • Here, of the ductal adenocarcinoma cases with the gene fusion, 75% were fused through deletion, and the remaining case was fused through translocation.
  • The TMPRSS2-ERG gene fusion was also rare in the acinar component of mixed ductal-acinar tumors when compared with the pure acinar adenocarcinoma controls (5 vs 45%, P=0.001, Fisher's exact test).
  • In 95% of the ductal adenocarcinoma cases in which a concurrent acinar component was analyzed, there was concordance for presence/absence of the TMPRSS2-ERG gene fusion between the different histologic subtypes.
  • In the control group of pure acinar adenocarcinoma cases, 59% were fused through deletion and 41% were fused through translocation.
  • The presence of the TMPRSS2-ERG gene fusion in some cases of prostatic ductal adenocarcinoma supports the concept that ductal adenocarcinoma and acinar adenocarcinoma may be related genetically.
  • However, the significantly lower rate of the gene fusion in pure ductal adenocarcinoma cases underscores the fact that genetic and biologic differences exist between these two tumors that may be important for future therapeutic strategies.

  • The patient underwent total cystoprostatectomy under the diagnosis of urothelial carcinoma of the urinary bladder four years earlier.
  • At the time, the prostatectomy specimen incidentally revealed a prostatic acinar adenocarcinoma at the bilateral peripheral zone.
  • A skin biopsy of the erythema revealed intraepithelial Paget's cells, and the patient underwent total penectomy under the diagnosis of extramammary Paget's disease.
  • Histopathological examination revealed continuous intraepithelial Paget's cells from the glans penis to the urethral navicular fossa, and a ductal carcinoma was detected beneath the urethral mucosa to the excisional margin.
  • Because the Paget's cells expressed cytokeratin 20, the tumor was diagnosed as Pagetoid spread rather than Paget's disease.
  • Re-examination of the previous prostatectomy specimen revealed prostatic duct adenocarcinoma with prostatic acinar adenocarcinoma.
  • Therefore, the final diagnosis was prostatic duct adenocarcinoma with Pagetoid spread to the glans penis.

  • [Title] [Clinical characteristics of prostatic adenocarcinoma with ductal features].
  • PURPOSE: To determine the incidence and prognosis of prostatic ductal adenocarcinoma.
  • We differentiated prostatic cases of ductal adenocarcinoma that were larger than 5 mm in diameter from cases of acinar adenocarcinomas.
  • RESULTS: We found eight cases (12%) of prostatic ductal adenocarcinoma among the 64 cases treated with radical prostatectomies.
  • Seven of the cases (11%) were mixed-type ductal adenocarcinomas, which contained acinar and ductal components.
  • In addition, one case was identified as pure ductal adenocarcinoma.
  • During the follow-up period, four of the eight cases of ductal adenocarcinoma (50%) and twelve of the 56 cases of acinar adenocarcinoma (21%) showed postoperative PSA failure.
  • CONCLUSIONS: We identified eight cases of ducal adenocarcinoma (12% of the examined cases), which suggests this disease is not as rare as previously reported.
  • Compared to the cases of acinar adenocarcinoma, the cases of ductal adenocarcinoma were at a more advanced pathological stage and resulted in a higher rate of postoperative PSA failure.
  • Therefore, we believe that patients that show even a limited degree of ductal adenocarcinoma should receive aggressive therapy.

  • Petraki et al have previously described presence of hK13 in salivary gland tissue, localized to duct epithelia and some acinar cells.
  • The aim of this study was to determine whether hK13 is expressed in salivary gland tissues and salivary gland tumors (both benign and malignant), in order to compare normal with tumor tissues.
  • Pleomorphic adenomas (PA), adenoid cystic carcinomas (ACC), polymorphous low grade adenocarcinomas (PLGA), acinic cell carcinomas (ACI), mucoepidermoid carcinomas (MEC) and adenocarcinomas not otherwise specified (ANOS) of both minor and major salivary glands were examined.
  • The results of this study indicate that most salivary gland tumors show high levels of expression of hK13.
  • Ductal cells and cells lining duct-like structures showed a higher intensity of staining than non-ductal cells in most tumors.
  • Tumors which exhibited only non-ductal cells also exhibited cytoplasmic staining.
  • In conclusion, we demonstrate the high expression of hK13 in several common salivary gland tumors.

  • Basal cell tumours of the prostatic gland are rare, and the classification is difficult.
  • In the present case report, a large, tumour-like proliferation of atypical basaloid cells was found incidentally in a prostatectomy specimen that otherwise contained a conventional acinar adenocarcinoma.
  • A high Ki-67 index was recorded within the atypical basaloid cells, by far exceeding the one counted in the conventional adenocarcinoma.
  • However, there were no definite criteria for a malignant behaviour of the basal cell tumour.
  • Comparative genomic hybridisation from microdissected tumour cells yielded losses at the short arms of chromosomes 8 and 12 in the conventional adenocarcinoma and a normal karyotype in the basal cell tumour.
  • The pathological findings favoured the diagnosis of an atypical basal cell hyperplasia.

  • [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.
  • 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.

  • [Title] Adenocarcinomas of the prostatic duct in necropsy material.
  • The general consensus about prostatic duct adenocarcinomas is that they have a rather aggressive biological behavior.
  • In addition, studies or reports of latent adenocarcinoma of the prostatic duct in necropsy material are scarce in the literature.
  • We report here three cases of adenocarcinoma of the prostatic duct that were found incidentally among 39 cases of latent acinar prostate adenocarcinomas in necropsy material.
  • We examined the morphologic and histological features of these prostatic duct adenocarcinomas, in order to better understand their biological behavior.
  • We identified two cases of mixed ductal-acinar adenocarcinoma and one case of pure ductal adenocarcinoma.
  • The finding of prostatic ductal adenocarcinomas among autopsy material, as well as some of their histological features, suggest that these tumors might have a similar biological potential as prostatic acinar cancer.

  • [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] 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.
  • By current convention, all high-grade intra-acinar and intraductal neoplastic lesions of prostatic origin fall under the diagnostic umbrella term: prostatic intraepithelial neoplasm (PIN).
  • Illustrating this fact, the well-described ductal subtype of prostatic adenocarcinoma is frequently associated with conventional-type acinar adenocarcinoma, and has a tendency to propagate within adjacent intact prostatic ducts.
  • Clearly, the misdiagnosis of lesions representing invasive disease as preinvasive has the potential for unfavourable clinical sequelae.
  • As yet, however, many of these lesions have escaped the establishment of reliable morphologic criteria or immunohistochemical differentiation for diagnosis.

  • [Title] Adenoid cystic/basal cell carcinoma of the prostate: review and update.
  • CONTEXT: Although most prostate carcinomas are of the conventional acinar type, unusual variants have been reported.
  • Adenoid cystic/basal cell carcinoma of the prostate is a rare tumor with distinctive histopathologic features.
  • There are only a few publications in the literature concerning the diagnosis, treatment, and prognosis of this neoplasm.
  • OBJECTIVE: To review current literature together with the clinical, pathologic, and immunohistochemical features of adenoid cystic/basal cell carcinoma of the prostate and offer a practical approach to the diagnosis--including the differential diagnosis--of this neoplasm in surgical pathologic specimens.
  • DATA SOURCES: Adenoid cystic/basal cell carcinoma of the prostate is composed of infiltrating basaloid cells forming dilated acinar and cribriform spaces with luminal basementlike material.
  • Differentiation of adenoid cystic/basal cell carcinoma from basal cell hyperplasia and cribriform pattern of acinar adenocarcinoma may be difficult.
  • CONCLUSIONS: Various histologic and immunohistochemical features are helpful in recognizing adenoid cystic/basal cell carcinoma of the prostate.
  • This is a rare subtype of prostate cancer and correct diagnosis is important because of the unique clinical and biological features and the implications for treatment and prognosis.

  • [Title] [Differential diagnosis of prostate cancer: impact of pattern analysis and immunohistochemistry].
  • 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.
  • Basal cell markers and the nuclear androgen receptors are important markers to differentiate Gleason grade 5 A und 5 B patterns from prostatic involvement by transitional cell carcinoma.

  • [Title] Ductal adenocarcinoma of the prostate: current opinion and controversies.
  • OBJECTIVE: To evaluate the morphologic spectrum and clinical significance of ductal adenocarcinoma of the prostate (DAP).
  • STUDY DESIGN: We reviewed diagnostic criteria, including the value of immunohistochemistry, and outlined the prognostic implications of a diagnosis of DAP.
  • Immunostaining for prostatic-specific antigen and prostate-specific acid phosphatase is present in these tumors, a high percentage of which overexpress alpha-methylacyl-coenzyme A racemase.
  • A basal cell layer can be seen in some of these tumors, which is probably due to tumor growth into preexisting ducts.
  • This usually represents an advanced stage of tumor progression and is not a precursor of invasive carcinoma.
  • CONCLUSION: DAP are neoplasms of prostatic origin, and the terms endometrioid or endometrial adenocarcinoma are best avoided.
  • The term ductal carcinoma is also inappropriate because this includes some urothelial carcinomas of ductal origin.
  • DAP are aggressive tumors with a shortened average time to progression compared with acinar adenocarcinoma.

  • [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] Immunohistochemical antibody cocktail staining (p63/HMWCK/AMACR) of ductal adenocarcinoma and Gleason pattern 4 cribriform and noncribriform acinar adenocarcinomas of the prostate.
  • Overexpression of alpha-methylacyl coenzyme A racemase (AMACR) in combination with absence of basal cell markers [ie, p63 and high molecular weight cytokeratin (HMWCK)] is typical of classic acinar prostatic adenocarcinoma.
  • We studied the expression and diagnostic utility of p63/HMWCK/AMACR immunohistochemical cocktail staining in ductal adenocarcinoma and cribriform Gleason pattern 4 acinar prostate cancer and compared it to noncribriform Gleason pattern 4 acinar prostate cancer.
  • One to 4 representative formalin-fixed paraffin-embedded archival tissue blocks from 62 radical prostatectomy specimens harboring prostate cancer of ductal (n=51), cribriform Gleason pattern 4 acinar (n=27), and noncribriform Gleason pattern 4 acinar adenocarcinoma (n=48) were included in this study.
  • The percentage of staining intensity and the presence of occasional basal cells positive with p63/HMWCK were recorded in each histologic type of prostatic adenocarcinoma.
  • Seventy-seven percent of ductal prostatic adenocarcinoma, 67% of cribriform acinar prostatic carcinoma, and 81% of noncribriform acinar prostatic carcinoma showed positive staining for AMACR.
  • There was no statistically significant difference between AMACR staining among the 3 histologic types, although there was a trend for noncribriform acinar prostatic carcinoma to have greater expression of AMACR than cribriform acinar prostatic carcinoma (P=0.07).
  • Staining was often heterogeneous, varying in staining intensities within the same histologic type of carcinoma.
  • Basal cells were detectable by p63 and HMWCK in a patchy fashion in 31.4% (16/51) of ductal and 29.6% (8/27) of cribriform acinar carcinomas compared with 2.1% (1/48) of noncribriform acinar carcinomas. In summary:.
  • (1) the majority of prostatic ductal and cribriform acinar carcinomas strongly expressed AMACR, however, subpopulations of these prostatic carcinoma were either completely negative or only weakly positive;.
  • (2) AMACR staining was often heterogeneous in intensity in the same histologic type of tumor, even within the same case;.
  • (3) patchy basal cell staining in noncribriform acinar prostatic carcinoma is rare.
  • In contrast, remnants of basal cells identified by p63/HMWCK were seen in a patchy fashion in a significant minority of both ductal and cribriform acinar prostatic adenocarcinoma, which most likely represents intraductal spread of tumor.

  • [Title] Do prostatic transition zone tumors have a distinct morphology?
  • Previous studies have proposed that the morphologic spectrum of prostatic glands of variable size with tall columnar cells displaying basally oriented nuclei and clear to pale pink cytoplasm (TZ-LOOK) is characteristic of the well to moderately differentiated component of transition zone (TZ) tumors.
  • In a recent report, we identified dominant peripheral zone (PZ) and TZ tumors situated anterior to the prostatic urethra.
  • Currently, we evaluate the histopathologic features of 215 dominant tumors, including 63 TZ and 73 anterior PZ lesions and an additional cohort of 79 posterior PZ tumors, in radical prostatectomy specimens, to identify the prevalence of this morphology in tumors of different zonal origin.
  • Each dominant tumor was assigned a TZ-LOOK extent score of 0 to 4, with 0 = no such morphology, 1 = 1% to 25%, 2 = 26% to 50%, 3 = 51% to 75%, and 4 = >75%.
  • Overall, 121/215 (56%) tumors showed some degree of this histology, including 56 of 63 (89%) TZ tumors and 65 of 152 (43%) PZ tumors (P<0.0001).
  • However, only 31/63 (49%) TZ tumors had >50% TZ-LOOK.
  • Among PZ tumors, 6/152 (4%) had predominant (>50%) TZ-LOOK morphology, yet 23/152 (15%) of all PZ tumors and 23/65 (35%) of PZ tumors displaying any degree of TZ-LOOK had scores of 2 to 3 (>25%; nonfocal).
  • In tumors of both zones with predominant (scores 3 to 4; >50%) TZ-LOOK histology, darker glands of usual acinar adenocarcinoma was often seen at the periphery.
  • Conversely, in tumors with nonpredominant TZ-LOOK (scores 1 to 2; <or=50%), these glands were frequently admixed with small glands bearing dark cytoplasm.
  • In this series, we demonstrate that some degree of TZ-LOOK morphology is twice as frequent in dominant TZ tumors than in PZ tumors.
  • Tumors demonstrating >50% of this histology are very likely of TZ origin, but this scenario occurs in only half of TZ tumors.
  • Importantly, the TZ-LOOK is nonfocal in up to 35% of PZ tumors exhibiting any degree of this morphology.

  • BACKGROUND: Prostatic neuroendocrine carcinomas comprise <1% of all prostate neoplasms, and approximately 200 cases have been reported in the literature.
  • We undertook this study to describe the experience in the management of prostatic neuroendocrine carcinoma with androgen-deprivation therapy (ADT).
  • Patients were selected by anatomopathological diagnostic study of neuroendocrine carcinoma including pure and mixed variants.
  • Symptoms at diagnosis were associated with metastasis to other organs, one with bone metastasis, and presenting pain in 100% of the cases.
  • In six (60%) patients mixed variant was documented (acinar adenocarcinoma and neuroendocrine carcinoma) with a median survival of 11.6 months.
  • In four patients (40%), pure neuroendocrine carcinoma was documented with a median survival of 7 months.
  • CONCLUSIONS: Prostatic neuroendocrine carcinoma is uncommon, aggressive and represents a prostatic neoplasia without PSA expression.
  • In advanced disease, very low response is reached with ADT.

  • 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.
  • The evaluation was carried out on 20 cystoprostatectomies (CyPs) with incidental PCa from men with bladder urothelial carcinoma (UC), and 20 radical prostatectomies (RPs) with hormonally untreated PCa from men with clinically detected PCa.
  • However, there are no significant differences between CyPs with incidental prostate carcinoma and RPs with clinically diagnosed cancer.

  • [Title] Characterization of ETS gene aberrations in select histologic variants of prostate carcinoma.
  • Histologic variants of prostate carcinoma account for 5-10% of the disease and are typically seen in association with conventional acinar carcinoma.
  • Recently, recurrent gene fusions between the androgen-regulated gene TMPRSS2 and the ETS transcription factors ERG, ETV1, ETV4, or ETV5 have been identified in a majority of conventional prostate carcinomas.
  • However, the frequency and significance of this critical molecular event is unknown in the histologic variants of prostate carcinoma.
  • Here, we used break-apart fluorescence in situ hybridization to assess TMPRSS2 and ETS aberrations in a series of select histologic variants: foamy gland carcinoma (N=17), ductal adenocarcinoma (N=18), mucinous carcinoma (N=18), and small cell carcinoma (N=7).
  • A histologic variation of acinar adenocarcinoma, demonstrating glomeruloid morphology (N=9), was also investigated.
  • TMPRSS2:ERG fusion was identified in 83% (15/18), 71% (5/7), 50% (9/18), 33% (3/9), and 29% (5/17) of mucinous, small cell, ductal, glomeruloid, and foamy gland prostate carcinomas, respectively.
  • Previously, we reported that 100% of androgen-independent metastatic prostate carcinomas harboring TMPRSS2:ERG gene fusion were associated with interstitial deletion (Edel).
  • Interestingly, ERG rearrangement in small cell carcinomas occurred exclusively through Edel, supporting the notion that TMPRSS2:ERG with Edel is an aggressive molecular subtype.
  • SPINK1, a biomarker expressed exclusively in a subset of ETS negative prostate carcinomas, was expressed in 6% of ETS negative histologic variants, specifically in ductal adenocarcinoma.
  • Notably, 88% (43/49) variant morphologies in this cohort showed concordance of TMPRSS2:ERG fusion with associated conventional acinar type, suggesting that variant morphology is clonally related to the latter.
  • Overall, our data provide insight into the origin, molecular mechanism, and phenotypic association of ETS fusions in histologic variants of prostate carcinoma.

  • [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] 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.

  • [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.

  • [Title] The distribution of PAX-2 immunoreactivity in the prostate gland, seminal vesicle, and ejaculatory duct: comparison with prostatic adenocarcinoma and discussion of prostatic zonal embryogenesis.
  • We studied PAX-2 expression in epithelium of normal seminal vesicle, normal ejaculatory duct, normal prostatic secretory epithelium, and prostatic adenocarcinoma to define its immunoreactivity pattern throughout the prostate gland and to evaluate its potential diagnostic role in the discrimination of seminal vesicle/ejaculatory duct epithelium from prostatic adenocarcinoma.
  • Prostatectomy specimens from 12 patients were reviewed to identify blocks containing seminal vesicle, ejaculatory duct, periurethral glands, benign prostatic glands, and prostatic acinar adenocarcinoma.
  • In addition, 2 tissue microarrays representing 15 additional seminal vesicles and 45 prostatic adenocarcinomas, 7 whole sections from prostatic adenocarcinomas of the central zone, and 5 core needle biopsies of seminal vesicle were also evaluated with anti-PAX-2 antibody.
  • In the 12 radical prostatectomy whole sections, nuclear reactivity for PAX-2 was identified in 12 (100%) of 12 of the seminal vesicle epithelium, 9 (90%) of 10 of the ejaculatory duct epithelium, 0 of 12 of the prostatic adenocarcinoma, and 0 of 6 of the high-grade prostatic intraepithelial neoplasia.
  • All 20 total additional seminal vesicles were positive for PAX-2 in the tissue microarray and biopsies; and all 52 additional prostatic adenocarcinomas were negative, including 7 of central zone origin.
  • No reactivity for PAX-2 was seen in prostatic adenocarcinoma or high-grade prostatic intraepithelial neoplasia.

  • The histologic type was acinar adenocarcinoma in 137, mucinous adenocarcinoma in 1, and ductal adenocarcinoma in 1.
  • The median tumor number in each prostate gland was 2.
  • The main tumor location was distributed in peripheral zone (76.3%), followed by the transitional zone (15.1%).
  • The Gleason score of the largest tumor was 2 to 4 in 1.5%, 5 to 6 in 7.9%, 7 in 48.9%, and 8 to 10 in 41.7%.
  • Extraprostatic tumor extension, seminal vesicle invasion, and lymph node metastasis were found in 59.0%, 28.8%, and 13.7% of the patients, respectively.
  • The clinical stage (P = 0.0059), serum prostate-specific antigen (PSA) level (greater than 20 ng/mL versus 10 ng/mL or less, P = 0.002), extraprostatic extension (P = 0.0012), seminal vesicle invasion (P <0.0001), and surgical margin status (P <0.0001) were all significant factors for disease progression on univariate analysis.
  • CONCLUSIONS: The patients with prostate cancer cared for at the Koo Foundation Sun Yat-Sen Cancer Center were older and had greater PSA levels, a more advanced stage, higher grade tumors, and high positive surgical margin rates.

  • [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.

  • The grading of variants and subtypes of acinar adenocarcinoma of the prostate, including cancer with vacuoles, foamy gland carcinoma, ductal adenocarcinoma, pseudohyperplastic carcinoma and small cell carcinoma have also been modified.
  • For needle biopsy with different cores showing different grades, the current recommendation is to report the grades of each core separately, whereby the highest grade tumor is selected as the grade of the entire case to determine treatment, regardless of the percent involvement.

  • [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] Fluorescence in situ hybridization to visualize genetic abnormalities in interphase cells of acinar cell carcinoma, ductal adenocarcinoma, and islet cell carcinoma of the pancreas.
  • OBJECTIVE: To use fluorescence in situ hybridization (FISH) to visualize genetic abnormalities in interphase cell nuclei (interphase FISH) of acinar cell carcinoma, ductal adenocarcinoma, and islet cell carcinoma of the pancreas.
  • PATIENTS AND METHODS: Between April 4, 2007, and December 4, 2008, interphase FISH was used to study paraffin-embedded preparations of tissue obtained from 18 patients listed in the Mayo Clinic Biospecimen Resource for Pancreas Research with a confirmed diagnosis of acinar cell carcinoma, ductal adenocarcinoma, islet cell carcinoma, or pancreas without evidence of neoplasia.
  • RESULTS: FISH abnormalities were observed in 12 (80%) of 15 patients with pancreatic cancer: 5 of 5 patients with acinar cell carcinoma, 5 of 5 patients with ductal adenocarcinoma, and 2 (40%) of 5 patients with islet cell carcinoma.
  • Gains of CTNNB1 due to trisomy 3 occurred in each tumor with acinar cell carcinoma but in none of the other tumors in this study.
  • FISH abnormalities of all other cancer genes studied were observed in all forms of pancreatic tumors in this investigation.
  • CONCLUSION: FISH abnormalities of CTNNB1 due to trisomy 3 were observed only in acinar cell carcinoma.
  • FISH abnormalities of genes implicated in familial cancer, tumor progression, and the 5-fluorouracil pathway were common but were not associated with specific types of pancreatic cancer.

  • [Title] Primary acinar cell carcinoma of the liver.
  • We report a case of acinar cell carcinoma primary to the liver.
  • The tumor was diagnosed in a 35-year-old woman complaining of abdominal pain and asthenia; serum alpha-fetoprotein (AFP) levels were increased at 6,000 IU/mL; imaging studies showed a hypervascular mass located in the left lobe of the liver.
  • The tumor had a heterogeneous appearance.
  • In well-differentiated areas, tumor cells formed acinar structures, had a pyramidal shape and a highly eosinophilic, granular cytoplasm, PAS diastase resistant.
  • In less-differentiated areas, tumor cells were endocrinelike.
  • The immunohistochemical study showed that tumor cells expressed trypsin.
  • The final diagnosis, based on histological, immunohistochemical, and ultrastructural arguments, was extra-pancreatic acinar cell carcinoma, primary to the liver.
  • This unusual lesion is likely to be the result of an abnormal differentiation pathway involving a transformed multipotential progenitor cell.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Long-term survival in a patient with acinar cell carcinoma of pancreas. A case report and review of literature.
  • CONTEXT: Acinar cell carcinoma of the pancreas is a rare malignancy that may have acinar and endocrine differentiation.
  • Clinical practice guidelines exist for pancreatic ductal adenocarcinoma.
  • However, treatment protocols for acinar cell carcinoma of the pancreas have not been standardized.
  • CASE REPORT: We describe a case of a 44-year-old woman presenting with low grade fever and mid-abdominal tenderness secondary to a pancreatic mass with acinar and endocrine differentiation metastatic to the liver.
  • The patient developed Clostridium difficile colitis and septic shock resulting in death 37 months after the diagnosis of acinar cell carcinoma of the pancreas.
  • CONCLUSION: This is a case of acinar cell carcinoma of the pancreas with an endocrine component, treated with multiple chemotherapeutic agents, in which the patient survived 37 months after diagnosis.

  • [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] CT and MRI features of pure acinar cell carcinoma of the pancreas in adults.
  • OBJECTIVE: We sought to describe the CT and MRI features of pure acinar cell carcinoma of the pancreas in adults.
  • MATERIALS AND METHODS: Eleven patients (six women and five men; mean age, 64 years) with acinar cell carcinoma, documented by pathologic examination of resected specimens, underwent CT (n=9) or MRI (n=2) examinations.
  • Two radiologists evaluated imaging studies and determined, by consensus, the following data for each tumor: size, location, margination, internal density or signal intensity, and contrast enhancement pattern.
  • Imaging features were correlated with gross and microscopic pathologic features of the tumors.
  • Tumors were oval (n=5), round (n=4), or lobular (n=2).
  • Five (45%) masses enhanced homogeneously; the remaining tumors contained cystic areas.
  • One patient had metastatic liver disease at presentation.
  • CONCLUSION: Pure acinar cell carcinoma of the pancreas is usually an exophytic, oval or round, well-marginated, and hypovascular mass on CT and MRI.

  • 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.

  • 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.
  • 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] Acinar cell carcinoma of the pancreas: is the absence of neuroendocrine component related to a more malignant behavior?
  • BACKGROUND/AIMS: Acinar cell carcinomas are uncommon malignant tumors of the pancreas, accounting for 1-2% of all the cases of exocrine pancreatic tumor.
  • Some authors have estimated acinar cell tumors to be as aggressive as ductal adenocarcinoma of the pancreas whereas other series showed acinar cell tumors to have a favorable clinical outcome.
  • This discrepancy in prognosis may be related to the cellular components of the tumor.
  • METHODOLOGY: With the aim to evaluate the possible relationship between the presence of neuroendocrine differentiation and behavior of these tumors, the authors reviewed all patients presenting acinar cell carcinoma of the pancreas in the last 5 years with emphasis in the immunohistochemical evaluation.
  • Two patients without neuroendocrine component had a disseminated disease at presentation.
  • This data suggests that this tumor is less aggressive than ductal adenocarcinoma and even with nodal involvement, long-term survival after complete resection can be achieved.
  • Due to the rarity of this pancreatic tumor, this relationship remains to be confirmed with a multicentric study including a larger number of patients.

  • [Title] Acinar cell carcinoma of the pancreas metastatic to the ovary: a report of 4 cases.
  • We report 4 cases of acinar cell carcinoma of the pancreas, 3 presenting as metastases in the ovary, the first report of this circumstance, which may pose a broad differential diagnosis and caused significant diagnostic difficulty in all the cases.
  • In 3 cases, the ovarian tumors were detected before the pancreatic tumor; in 1 case, a large abdominal mass and ovarian tumors were discovered synchronously.
  • The ovarian tumors were large, solid, white-tan on gross examination, and bilateral in 3 cases; the single case involving only 1 ovary had 2 discrete masses of tumor.
  • Two cases had a predominant acinar growth pattern of cells with brightly eosinophilic, granular cytoplasm.
  • The main differential diagnostic consideration was well-differentiated neuroendocrine neoplasm (carcinoid tumor); positive immunostaining with antibodies against chymotrypsin and trypsin and negative immunostaining with antibodies against synaptophysin and chromogranin helped exclude this diagnosis.
  • We observed focal alpha-inhibin immunostaining in 2 cases, which may represent a potential diagnostic pitfall, as a Sertoli cell tumor or unusual granulosa cell tumor may also enter the differential diagnosis.
  • Inclusion of antibodies against the pancreatic enzymes chymotrypsin and trypsin in the immunohistochemical panel is critical in establishing the correct diagnosis and should be considered when evaluating ovarian tumors with architectural (mainly acinar) and cytologic (granular eosinophilic cytoplasm) characteristics that should bring a metastatic acinar cell carcinoma into consideration.

  • [Title] Liver metastases of pancreatic acinar cell carcinoma with marked nuclear atypia and pleomorphism diagnosed by EUS FNA cytology: a case report with emphasis on FNA cytological findings.
  • BACKGROUND: Acinar cell carcinoma of the pancreas is a rare neoplasm.
  • Although this tumor has been well characterized histologically, the morphological patterns in Fine Needle Aspiration Cytology have not been well defined.
  • Unlike ductal adenocarcinomas, endocrine tumors, and solid pseudopapillary tumors of the pancreas with their characteristic FNA cytological features, acinar cell carcinomas pose a particular diagnostic challenge by sharing many cytomorphologic features with endocrine tumors of the pancreas.
  • FNA cytology revealed abundant, loosely cohesive clusters of malignant epithelial cells with vaguely acinar and trabecular formations.
  • Scattered, strikingly large tumor cells with giant nuclei, prominent mitoses and associated necrosis were evident.
  • A pancreatic endocrine tumor was suspected initially, but acinar cell carcinoma of the pancreas was confirmed by immunohistochemistry, cytochemical and ultrastructural studies.
  • CONCLUSION: We describe a case of pancreatic acinar cell carcinoma with unusual cytomorphologic features mimicking an endocrine tumor of pancreas, encountered in endoscopic ultrasound-guided fine needle aspiration of a metastatic liver mass and discuss the diagnostic approach for this unusual pancreatic tumor in fine needle aspiration cytology.

  • [Title] Acinar cell carcinoma of the pancreas: an institutional series of resected patients and review of the current literature.
  • INTRODUCTION: Acinar cell carcinoma (ACC) is a rare, malignant neoplasm with a generally poor prognosis.
  • MATERIALS AND METHODS: The Johns Hopkins pathology prospective database was reviewed from 1988 to 2006 to identify patients with pancreatic neoplasms possessing features of acinar cell differentiation.
  • Median tumor size was 3.9 cm with 12 patients found to have stage IIB disease or worse.
  • Eight of the fourteen patients developed recurrent disease.
  • Overall median survival and disease-free survival were 33 and 25 months, respectively, as compared to a median survival of 18 months for pancreatic adenocarcinoma.
  • CONCLUSION: Acinar cell carcinomas are rare, aggressive neoplasms that are difficult to diagnose and treat.
  • These lesions have a better prognosis than the more common pancreatic adenocarcinomas.

  • [Title] 672 patients with acinar cell carcinoma of the pancreas: a population-based comparison to pancreatic adenocarcinoma.
  • BACKGROUND: Acinar cell carcinoma (ACC) is a rare cancer of the pancreas accounting for approximately 1% of nonendocrine tumors.
  • Because no large series of patients with ACC exist, our understanding of this disease comes mainly from small retrospective reports and anecdotal experience.
  • OBJECTIVE: Our goal was to evaluate a large population-based cohort of patients with ACC and compare their demographic factors and outcomes to those of patients with pancreatic adenocarcinoma (PA).
  • The demographic factors, tumor characteristics, resection status, and long-term survival were compared between the 2 groups.
  • The mean age at the time of diagnosis was significantly lower for ACC than PA (56 years vs 70 years, P < .001).
  • Based on SEER clinical staging, patients with ACC were less likely to have unstaged disease (8% vs 18%).
  • Of the 616 patients with staged ACC, 16% had localized disease, 26% had regional disease, and 58% had distant disease.
  • In the 47,896 staged patients with PA, 10% had localized disease, 33% had regional disease, and 57% had distant disease (P < .0001 compared to ACC).
  • Based on clinical extent of disease, 81% of patients with locoregional ACC and 70% of patients with locoregional PA were resectable.
  • However, only 69% of ACC patients with locoregional disease and 27% of PA patients with locoregional disease underwent surgical resection.
  • Multivariate Cox proportional hazards regression model results suggested patients with ACC were less likely to die (hazard ratio = 0.241; 95% confidence interval, 0.22-0.27) than patients with PA after controlling for gender, race, stage, SEER region of diagnosis, and surgical resection status.
  • CONCLUSIONS: Consistent with anecdotal reports and previous retrospective studies, ACC is a more indolent disease than PA.
  • Patients with ACC tend to present at a younger age, are more likely to have resectable disease, and are much more likely to undergo potentially curative resection.

  • 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] Pancreatic acinar cell carcinoma with intracranial metastasis in a dog.
  • This report concerns a case of pancreatic carcinoma with widespread metastases to many organs including intracranial metastasis.
  • An eleven-year-old, male, mixed-breed dog showed emaciation, ataxia, and multiple visible tumors within the neck.
  • Based on gross and microscopic examination, the primary tumor cells were located in the left lobe of the pancreas and widespread metastasis was found into various organs, including the brain, lungs, liver, kidneys, tonsils, serosal surface of the esophagus, and submandibular, pulmonary hilar, mediastinal, and mesenteric lymph nodes.
  • This case indicates that pancreatic adenocarcinoma should be included in the differential diagnosis list when cervical neck masses are detected.

  • [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] 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.

  • [Title] Subcutaneous fat necrosis as the presenting feature of a pancreatic carcinoma: the challenge of differentiating endocrine and acinar pancreatic neoplasms.
  • The association between pancreatic panniculitis and pancreatic disease is well described, but differentiation among the neoplastic causes of the syndrome remains difficult due to substantial overlap in histological and immunohistochemical features.
  • We report a case of subcutaneous fat necrosis as the presenting feature in a 61-year-old man with metastatic carcinoma of pancreatic origin.
  • Previous pathological evaluation of the patient's liver biopsy led to an initial diagnosis of adenocarcinoma of unknown primary site.
  • Immunohistochemistry was consistent with neuroendocrine differentiation, but the patient rapidly decompensated and died before the evaluation was complete, leaving the definitive diagnosis in question.
  • In our review of the published reports of tumor types associated with pancreatic panniculitis, we found that immunohistochemical staining and electron microscopy can and should be used in conjunction with clinical correlation to accurately differentiate neuroendocrine tumors from carcinomas with acinar cell features.
  • Accurate diagnosis of these tumors is necessary to determine prognosis and define appropriate therapy.

  • [Title] The monoclonal anti-BCL10 antibody (clone 331.1) is a sensitive and specific marker of pancreatic acinar cell carcinoma and pancreatic metaplasia.
  • Acinar cell carcinoma (ACC) is a rare pancreatic cancer which may be difficult to distinguish from other solid nonadenocarcinoma tumors.
  • The diagnosis depends on the demonstration of acinar differentiation, obtained with antibodies recognizing various pancreatic enzymes that, although specific, show different sensitivity.
  • The C-terminal portion of the BCL10 protein shows homology with carboxyl ester hydrolase (CEH), an enzyme produced by pancreatic acinar cells.
  • We investigated the usefulness of a C-terminal BCL10 monoclonal antibody in the diagnosis of ACCs.
  • We examined normal pancreases and different pancreatic tumors including ACCs, mixed acinar-endocrine carcinomas, ductal adenocarcinomas, mucinous, serous, solid pseudopapillary, and endocrine neoplasms.
  • In addition, various normal tissues and cases of pancreatic metaplasia of the gastroesophageal mucosa, cases of ectopic pancreas, gastrointestinal endocrine tumors, salivary and breast acinic cell carcinomas, gastric adenocarcinomas with and without acinar differentiation, and hepatocellular carcinomas were studied.
  • BCL10 immunoreactivity paralleled that of CEH and was restricted to acinar cells of normal and ectopic pancreas, of pancreatic metaplasia, and of ACCs.
  • We suggest using BCL10 antibody for diagnosing pancreatic tumors and whenever an acinar differentiation is suspected in gastrointestinal neoplastic and metaplastic lesions.

  • 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.

  • Primary epithelial tumors of the pancreas are extremely uncommon in children, and among these, acinar cell carcinoma (ACC) is the most rare.
  • The histologic diagnosis of ACC was supported by both immunohistochemistry and electron microscopy.
  • Despite its rarity, ACC should be kept in the differential diagnosis of pediatric pancreatic exocrine tumors.
  • We also provide a comparison with an example of solid pseudopapillary tumor, another relatively infrequent epithelial tumor of the pancreas in the young.

  • [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] Metastatic acinic cell carcinoma in a neurofibroma mistaken for carcinosarcoma.
  • BACKGROUND: Tumor-to-tumor metastasis is a rare, but well-recognized, entity most commonly involving metastatic carcinoma to a mesenchymal neoplasm.
  • We report a case of acinic cell carcinoma of the parotid gland metastatic to a neurofibroma.
  • METHODS AND RESULTS: A 55-year-old man with a history of a high-grade acinic cell carcinoma of the parotid was seen with a mass at the surgical site and metastatic foci in the scalp 10 months postoperatively.
  • The resection specimen revealed a spindle cell lesion with metastatic foci of high-grade adenocarcinoma, initially diagnosed as a carcinosarcoma.
  • The bland morphology and S-100-positive expression of the spindle cell lesion confirmed the diagnosis of neurofibroma.
  • The high-grade features of the carcinomatous foci and their similarity to the primary tumor confirmed the presence of a tumor-to-tumor metastasis.
  • CONCLUSION: To our knowledge, this is the first reported case of acinic cell carcinoma metastatic to a neurofibroma, an important entity in the differential diagnosis of biphasic tumors of the head and neck.

  • [Title] Acinic cell carcinoma of the head and neck: radiologic-pathologic correlation.
  • OBJECTIVE: To describe and correlate the imaging and pathologic findings of acinic cell carcinoma (ACC) in the head and neck.
  • A parapharyngeal lesion was cystic mass with mural nodule, and a submandibular and a palate tumor were cystic lesions on CT.
  • CONCLUSION: Although ACC appears to have nonspecific imaging findings, familiarity with some imaging features can be helpful for differential diagnosis of head and neck tumors.

  • 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 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.
  • In the collected specimen of the tumour on the front thoracic wall, a diagnosis of acinic cell carcinoma was made.

  • 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] 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.

  • Positive staining was observed with Periodic acid-Shiff, and immunohistochemistry for cytokeratin, alpha-1 antitrypsin, and S-100 protein resulting in a final diagnosis of acinic cell carcinoma.
  • Acinic cell carcinoma represents a well-established, although uncommon, entity in the classification of neoplasms of salivary gland origin.
  • The parotid salivary gland is the most frequent site of acinic cell carcinoma, whereas the lip is a particularly unusual site.
  • Given these findings, we suggest that acinic cell carcinoma should be considered in the differential diagnosis of any mucocele-like mass on the lower lip.

  • [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.
