  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Basal cell adenocarcinoma of minor salivary glands.
  • Basal cell adenocarcinoma of minor salivary glands is a relatively rare slow-growing tumor with an infiltrating growth pattern.
  • The infiltrating growth pattern and likelihood of vascular and perineural involvement distinguishes basal cell adenocarcinoma from basal cell adenoma.
  • Basal cell adenocarcinomas show strong immunoreactivity to cytokeratin 7 and variable myoepithelial staining with S100.
  • It is necessary to differentiate basal cell adenocarcinoma from other basaloid cell tumors of the minor salivary glands because of the prognosis and potential differences in treatment, particularly adenoid cystic adenocarcinoma and basaloid squamous carcinoma.
  • Surgical excision with a wide margin to ensure complete removal has been suggested as the primary treatment for basal cell adenocarcinoma.

  • [Title] Fine-needle aspiration cytology of basal cell adenoma of the parotid gland: characteristic cytological features and diagnostic pitfalls.
  • We retrospectively studied the cytological features of aspiration cytology in 12 cases of basal cell adenoma (BCA) and 5 cases mistakenly diagnosed as BCA.
  • The characteristic cytological features of solid type BCA were three-dimensional clusters in 71%, sharp-angle small clusters in 86%, basement membrane- like material in 71%, and cell crush in 86%.
  • In contrast, 3 of the 5 cystic type BCA cases showed inadequate cellular components or no basaloid tumor cells, and the cytological diagnosis of BCA could not be determined.
  • In the 5 cases misdiagnosed as BCA, there were 2 cases of pleomorphic adenoma, 2 cases of benign lymphoepithelial cyst, and 1 case of basal cell adenocarcinoma.
  • Accurate differential cytological diagnosis of BCA is relatively easy to determine the solid type BCA, but is more difficult for cystic type BCA.

  • INTRODUCTION: Basal cell adenoma (BCA) is a rare benign neoplasm characterized by the basaloid appearance of the tumour cells and the lack of myxo-chondroid stromal component present in pleomorphic adenoma.
  • AIM: We report a case of basal cell adenoma of membranous type, highly suspected of malignancy because of the presence of mediastinal lymph nodes and pulmonary nodules which finally were related to an associated sarcoidosis.
  • So the diagnosis of metastatic malignant salivary gland tumor was suspected.
  • Finally, the histological examination concluded to a basal cell adenoma of membranous type with sarcoidosis granulomas in the parotid and in the lymph nodes.
  • When the malignancy is suspected, like in our case, this tumor must be differentiated from the basal cell adenocarcinoma using histological criteria.

  • 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.

  • [Title] Atypical presentation of oral basaloid squamous cell carcinoma.
  • AIM: The purpose of this report is to present the clinical and histological features of a basaloid squamous cell carcinoma (BSCC) occurring in the retromolar trigone of a 59-year-old man and to relate its immunohistochemical characteristics.
  • BACKGROUND: BSCC is an aggressive distinct variant of squamous cell carcinoma (SCC) requiring recognition as a separate entity from SCC due to its peculiar behavior.
  • SUMMARY: Since this tumor can mimic other neoplasms such as adenoid cystic carcinoma, neuroendocrine carcinoma, and basal cell adenocarcinoma, histological features are essential to differentiate between them.

  • OBJECTIVE: To formulate cytologic features for differential diagnosis of basal cell adenoma (BCA).
  • STUDY DESIGN: The usefulness of 5 items for a cytologically definitive diagnosis of BCA was examined.
  • The 5 items in 8 BCA and 22 non-BCA cases (adenoid cystic carcinoma [ADCC], basal cell adenocarcinoma, myoepithelioma, pleomorphic adenoma and polymorphous low-grade adenocarcinoma) that displayed mimicking cytology were examined cytologically.
  • RESULTS: The useful items were < 5.1 microm in mean of epithelial nuclear short diameter; mild atypia on definitive diagnosis; stromal cell cluster combining smooth margin surrounding the epithelial cell cluster or containing the epithelial cell cluster; epithelial clusters surrounded by or adhered to a thick, hyalinized smooth margin without stromal cluster; and closely fastened, tight clusters with denser cytoplasm than ADCC, but an indistinct border, with oval nuclei and no hyaline cells.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • Histologically, the tumors were classified as pleomorphic adenoma (n = 54), papillary cystadenoma (n = 1), adenoid cystic carcinoma (n = 10), mucoepidermoid carcinoma (n = 8), acinic cell carcinoma (n = 3), adenocarcinoma (n = 2), basal cell adenocarcinoma (n = 1), papillary cystadenocarcinoma (n = 1), and carcinoma in pleomorphic adenoma (n = 2).
  • From the results of the present study and review of the literature, it is suggested that the minor salivary gland tumors in Japan may be characterized by a higher incidence of benign tumors, especially of pleomorphic adenoma; a more marked tendency for female predominance; a higher incidence of palatal involvement; and a rarer occurrence of polymorphous low grade adenocarcinoma, in comparison with those reported in the literature from outside of Japan.

  • [Title] Hierarchical cluster analysis of myoepithelial/basal cell markers in adenoid cystic carcinoma and polymorphous low-grade adenocarcinoma.
  • Distinguishing adenoid cystic carcinoma from polymorphous low-grade adenocarcinoma of the salivary glands is important for their management.
  • We studied the expression of several myoepithelial and basal/stem cell markers (smooth muscle actin, calponin, smooth muscle myosin heavy chain, metallothionein, maspin, and p63) by immunohistochemistry in 23 adenoid cystic carcinoma and 24 polymorphous low-grade adenocarcinoma, to identify the most useful marker or combination of markers that may help their diagnoses.
  • We noted diffuse expression of smooth muscle actin in 20 adenoid cystic carcinoma vs one polymorphous low-grade adenocarcinoma (P<0.0001), calponin in 15 adenoid cystic carcinoma vs one polymorphous low-grade adenocarcinoma (P<0.0001), smooth muscle myosin heavy chain in 15 adenoid cystic carcinoma vs one polymorphous low-grade adenocarcinoma (P=0.001), metallothionein in 22 adenoid cystic carcinoma vs eight polymorphous low-grade adenocarcinoma (P<0.001), maspin in 22 adenoid cystic carcinoma vs 14 polymorphous low-grade adenocarcinoma, and p63 in 21 adenoid cystic carcinoma vs 14 polymorphous low-grade adenocarcinoma.
  • In differentiating adenoid cystic carcinoma from polymorphous low-grade adenocarcinoma, smooth muscle actin as a single ancillary test in support of the histological findings, appears to be as efficient as multiple immunohistochemical tests.

  • 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.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Immunolabeling pattern of cytokeratin 19 expression may distinguish sebaceous tumors from basal cell carcinomas.
  • BACKGROUND: Distinction between sebaceous tumors and basal cell carcinomas can often pose diagnostic problems.
  • Our aim was to evaluate the use of CK 19 staining patterns in differentiating between sebaceous tumors and basal cell carcinomas.
  • METHODS: Thirty-seven cases including 5 sebaceous adenomas, 16 sebaceous epitheliomas, 6 sebaceous carcinomas and 14 basal cell carcinomas (7 being of the morpheaform type and 7 nodular basal cell carcinomas) were tested with a monoclonal mouse antibody to human CK 19.
  • CK 19 was found to be strongly positive in 9/14 (64%) and focally positive in 2/14 (14%) of basal cell carcinomas.
  • CONCLUSION: CK 19 expression can be helpful in differentiating sebaceous tumors (including sebaceous adenomas, sebaceous epitheliomas and sebaceous carcinomas) from basal cell carcinomas and may be a useful adjunct when these entities are included in the differential diagnosis.

  • [Title] Basaloid adenocarcinoma. A new variant of pulmonary adenocarcinoma.
  • The 2004 WHO classification of lung tumours recognised basaloid carcinoma as a variant of squamous and large cell carcinoma.
  • We report a unique case of primary pulmonary adenocarcinoma with a basaloid component.
  • The patient is disease-free 13 months after diagnosis.
  • The former was an adenocarcinoma with mucus containing spaces lined by columnar mucinous cells and basaloid cells.
  • The solid component was an organoid proliferation of basaloid-type cells, as in cutaneous basal cell carcinoma.
  • (1) The solid areas resemble a conventional basaloid carcinoma, except for the presence of small mucin-containing spaces. (2) The mucinous adenocarcinoma areas contain two layers of columnar and basaloid cells. (3) Both components are neoplastic based on cell morphology, invasive properties and phenotypic profile.
  • These findings indicate that a basaloid variant of adenocarcinoma is also existing in the spectrum of basaloid carcinomas of the lung.

  • [Title] Prostate basal cell lesions can be negative for basal cell keratins: a diagnostic pitfall.
  • BACKGROUND: Prostate basal cell lesions can have architectural and cytologic atypia that mimic prostate adenocarcinoma.
  • Immunohistochemical stains for basal cell markers are most helpful in the differential diagnosis.
  • All of the published studies show basal cell lesions are positive for basal cell keratins, whereas adenocarcinoma is negative for both.
  • We reported two cases of prostate basal cell lesions with negative basal cell keratin expression by immunohistochemistry.
  • STUDY DESIGN: We reported the histologic and immunohistochemical profiles of two cases of basal cell lesions of the prostate.
  • RESULTS: Histologically, both cases were highly suspicious for prostate adenocarcinoma with infiltrative growth pattern and significant nuclear atypia.
  • The atypical glands in both cases were negative for basal cell keratins.
  • However, both lesions were positive for another basal cell marker, p63, confirming that they were basal cells in origin, rather than prostate adenocarcinoma.
  • CONCLUSION: Prostate basal cell lesions can occasionally be negative for basal cell keratins by immunohistochemistry and therefore may be misdiagnosed as prostate adenocarcinoma.
  • We recommend using both p63 and basal cell keratins simultaneously in the workup of atypical prostate lesions to avoid such a misdiagnosis.

  • [Title] Basal/myoepithelial cells in chronic sinusitis, respiratory epithelial adenomatoid hamartoma, inverted papilloma, and intestinal-type and nonintestinal-type sinonasal adenocarcinoma: an immunohistochemical study.
  • CONTEXT: The pathogenesis of respiratory epithelial adenomatoid hamartoma (REAH) and inverted papilloma (IP) is poorly understood, especially compared with sinonasal adenocarcinoma (SNAC).
  • One feature of malignant glandular lesions is loss of the basal/myoepithelial layer.
  • The immunophenotype of the basal/myoepithelial layer has not been fully examined in benign glandular lesions of the sinonasal tract.
  • OBJECTIVE: To examine benign and malignant glandular lesions in the sinonasal tract for the immunophenotype of basal/myoepithelial cells, proliferation index, and cytokeratin and intestinal differentiation profiles.
  • DESIGN: Sinonasal adenocarcinoma (intestinal-type adenocarcinoma [ITAC] and nonintestinal type adenocarcinoma [non-ITAC]), REAH, IP, and chronic sinusitis (CS) were stained for cytokeratin (CK) 7, CK20, 34betaE12, CDX-2, p63, Ki-67, smooth muscle actin (SMA), S100 protein, and calponin.
  • RESULTS: Basal/myoepithelial cells in CS and REAH were positive for p63 and 34betaE12 but negative for SMA, S100 protein, and calponin.
  • Sinonasal adenocarcinoma had the highest Ki-67 labeling index, and p63-positive SNACs had higher proliferation indices than p63-negative SNACs.
  • Sixty percent of morphologic ITACs expressed CDX-2.
  • CONCLUSIONS: Basal/myoepithelial cells in CS and REAH should be considered basal and not myoepithelial cells.

  • The adenoid cystic/basal cell carcinoma of the prostate is a rare tumor with distinctive histopathologic features.
  • There are quite few publications in the literature concerning the diagnosis, treatment, and prognosis of this neoplasm.
  • METHODS. A 71-year-old man had an increased PSA value (5.11 ng/dL); the prostatic biopsy examination was positive for adenoid cystic/basal cell carcinoma.
  • The histology examination showed an acinar conventional carcinoma and adenoid cystic/basal cell carcinoma.
  • CONCLUSIONS. Various histologic and immunohistochemical features are helpful in recognizing the adenoid cystic/basal cell carcinoma of the prostate.
  • Clinically, the only difference from a conventional adenocarcinoma is that the PSA value is usually normal or only slightly increased.

  • [Title] Basal cell hyperplasia: an unusual diagnostic dilemma on prostate needle biopsies.
  • Basal cell hyperplasia (BCH) is a well-recognized entity on transurethral resection specimens, but it is an uncommon finding on prostatic needle biopsies, and the diagnostic difficulties with it have not been fully defined on this material.
  • In all cases, the focus of BCH was referred for consultation to rule out adenocarcinoma.
  • Other minor patterns included cribriform (5), pseudocribriform (4), cords (1), and adenoid basal (1).
  • Basal cell hyperplasia, as a mimicker of cancer, is an uncommon entity encountered on prostatic needle biopsies.
  • Helpful features for its diagnosis include solid nests, pseudocribriform glands, multilayering of cells, calcifications, and cellular stroma.
  • Immunohistochemistry can be useful for documenting the basal cell layer and demonstrating negative racemase staining.

  • 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.

  • STUDY DESIGN: We reviewed diagnostic criteria, including the value of immunohistochemistry, and outlined the prognostic implications of a diagnosis of DAP.
  • A basal cell layer can be seen in some of these tumors, which is probably due to tumor growth into preexisting ducts.
  • CONCLUSION: DAP are neoplasms of prostatic origin, and the terms endometrioid or endometrial adenocarcinoma are best avoided.
  • DAP are aggressive tumors with a shortened average time to progression compared with acinar adenocarcinoma.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Immunohistochemical expression of D2-40 in benign and malignant sebaceous tumors and comparison to basal and squamous cell carcinomas.
  • The diagnosis of sebaceous carcinoma presents an important challenge to both clinicians and pathologists, as many cases are initially misdiagnosed both clinically and histopathologically, potentially leading to adverse medical and legal outcomes.
  • We studied the expression of D2-40 (podoplanin) by immunohistochemistry to determine if it can aid in this differential diagnosis and to evaluate the possibility of lymphangiogenesis in sebaceous carcinoma.
  • A total of 36 cases of sebaceous lesions, including 16 sebaceous carcinomas, 7 sebaceous adenomas, 6 sebaceomas, and 7 cases of normal glands and sebaceous hyperplasia, and 17 cases of basal cell carcinoma and 10 cases of squamous cell carcinoma, were also examined.
  • We also found D2-40 to be only weakly and focally positive in basal cell carcinoma and weakly to moderately positive in squamous cell carcinoma, which showed increased staining with decreased differentiation.
  • Therefore, overall, D2-40 is, of limited diagnostic utility in sebaceous lesions but may be useful in distinguishing sebaceoma and basaloid sebaceous carcinoma from basal cell carcinoma.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Diagnosis of adenocarcinoma in prostate needle biopsy tissue.
  • For patients with clinically localised prostate cancer, the diagnosis is typically established by histopathological examination of prostate needle biopsy samples.
  • Major and minor criteria are used to establish the diagnosis, based on the microscopic appearance of slides stained using haematoxylin and eosin.
  • Major criteria include an infiltrative glandular growth pattern, an absence of basal cells and nuclear atypia in the form of nucleomegaly and nucleolomegaly.
  • In difficult cases, basal cell absence may be confirmed by immunohistochemical stains for high-molecular-weight cytokeratins (marked with antibody 34betaE12) or p63, which are basal cell markers.
  • Cocktails of antibodies directed against basal cell markers and AMACR are particularly useful in evaluating small foci of atypical glands, and in substantiating a diagnosis of a minimal adenocarcinoma.
  • Reporting of adenocarcinoma in needle biopsy specimens should always include the Gleason grade and measures of tumour extent in the needle core tissue.

  • [Title] Distribution of basal/myoepithelial markers in benign and malignant bronchioloalveolar proliferations of the lung.
  • We investigated the staining pattern of commonly used basal cell/myoepithelial markers, such as p63 (a p53-homologous nuclear protein), basal cell-specific cytokeratin antibody (34betaE12, K903), and smooth muscle myosin heavy chain (SMMHC) in benign and malignant bronchioloalveolar proliferations of the lung.
  • We studied 85 lung lesions consisting of 35 bronchioloalveolar carcinoma, 30 well-differentiated adenocarcinoma, and 20 cases of benign lung lesions.
  • In normal lung, p63, K903, and SMMHC decorated the basal cells of large and small airways and occasional cells of terminal bronchioles.
  • In reactive processes, a distinctive staining pattern was present in 19/20 (95%) of the cases characterized by staining of basal cells of the airways and bronchiolar epithelium and squamous metaplastic epithelium for p63 and K903, whereas 12/20 (60%) stained with SMMHC.
  • For adenocarcinoma, a majority of the cases (28/30, 93%) were negative for p63 and K903; however, SMMHC showed artifactual staining in the desmoplastic stroma in 6/30 (20%) cases.
  • Our results highlighted the differential expression of basal cell markers across various bronchioloalveolar lesions.
  • The staining pattern of basal cells in bronchioloalveolar carcinoma supports that these neoplasms may actually be carcinoma in-situ.

  • [Title] Atypical sclerosing adenosis of the prostate: a rare mimic of adenocarcinoma.
  • AIMS: Sclerosing adenosis of the prostate is a benign, small, acinar proliferation in dense spindle cell stroma, with a distinct immunohistochemical profiles.
  • METHODS AND RESULTS: We describe five cases of sclerosing adenosis with significant cytological atypia, referred to as atypical sclerosing adenosis (ASA), which were initially considered suspicious or diagnostic of adenocarcinoma.
  • All cases of typical and atypical sclerosing adenosis displayed an intact basal cell layer, which was immunoreactive for high-molecular-weight keratin, S100 protein, smooth muscle actin, and prostate-specific antigen, with no differences between ASA and the control group.
  • CONCLUSIONS: ASA is an unusual small, acinar proliferation of the prostate that may be mistaken for adenocarcinoma, and should be distinguished from other mimics, including atypical adenomatous hyperplasia, mesonephric remnant hyperplasia, and post-atrophic hyperplasia.

  • INTRODUCTION AND OBJECTIVES: The diagnosis of invasive adenocarcinoma of the prostate is often difficult in needle prostatic cores, where, additionally, the assessment of the presence of basal cells has demonstrated to be of paramount importance.
  • In our study, we analyzed comparatively the expression of 34betaE12, p63, bcl-2 and alpha-methylacyl-CoA racemase in order to evaluate the usefulness of bcl-2 as a new marker of the basal cells in prostatic pathology.
  • METHODS AND RESULTS: This study comprises radical prostatectomy specimens from 48 patients which were studied in order to determine the lack of staining of basal cells in invasive tumor areas together with the expression of racemase.
  • Likewise, the presence of basal cells in areas of atrophy, hyperplasia, adenosis, and high-grade prostatic intraepithelial neoplasia (PIN) was also examined.
  • Within the areas of adenosis and PIN a discontinuous pattern of basal cell expression was found in some cases.
  • In 2 out of 48 cases (4,2%) of invasive carcinoma a weak bcl-2 expression without a basal cell distribution was found.
  • CONCLUSIONS: In addition to classical markers, we demonstrated the diagnostic value of bcl-2 as a new basal cell marker.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Stratified epithelium in prostatic adenocarcinoma: a mimic of high-grade prostatic intraepithelial neoplasia.
  • Typically glands of prostatic adenocarcinoma have a single cell lining, although stratification can be seen in invasive carcinomas with a cribriform architecture, including ductal carcinoma.
  • The histomorphological features and immunohistochemical profile of cases of non-cribriform prostatic adenocarcinoma with stratified malignant glandular epithelium were analyzed.
  • These cases were identified from needle biopsy cases from the consultation files of one of the authors and from a review of 150 consecutive in-house needle biopsy cases of prostatic adenocarcinoma.
  • The main attribute in all these foci was the presence of glandular profiles lined by several layers of epithelial cells with cytological and architectural features resembling flat or tufted high-grade prostatic intraepithelial neoplasia, but lacking basal cells as confirmed by negative 34betaE12 and/or p63 immunostains in all cases.
  • The AMACR staining profile of the stratified foci was variable, with 4 foci showing positivity, and 3 foci being negative, including two cases that displayed AMACR positivity in adjacent non-stratified prostatic adenocarcinoma.
  • Prostatic adenocarcinoma with stratified malignant glandular epithelium can be identified in prostate needle biopsy samples harboring non-cribriform prostatic adenocarcinoma and resembles glands with high-grade prostatic intraepithelial neoplasia.
  • Recognition of this pattern of prostatic adenocarcinoma is necessary to correctly diagnose such cases as invasive carcinoma.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Cell polarity protein Lgl2 is lost or aberrantly localized in gastric dysplasia and adenocarcinoma: an immunohistochemical study.
  • The diagnosis of gastric epithelial dysplasia, a precursor lesion of gastric adenocarcinoma, is hindered by interobserver variability and by its resemblance to regenerative changes.
  • Loss of cell polarity, a histological feature of gastric epithelial dysplasia, may be difficult to ascertain, especially in the setting of inflammation or injury.
  • A biomarker of cell polarity could be useful in diagnosis of dysplasia, but has not been reported.
  • The Lethal giant larvae (lgl) gene controls apical-basal polarity of epithelial cells in Drosophila, and has properties of a tumor-suppressor gene.
  • The goal of our study was to test the hypothesis that Lgl2 protein expression and/or localization are disrupted in gastric epithelial dysplasia and adenocarcinoma.
  • Routinely processed pathology specimens including 94 benign mucosae of digestive organs, in addition to 36 reactive gastropathy, 57 gastric epithelial dysplasia, and 77 gastric adenocarcinomas, were immunostained for Lgl2 protein.
  • All but one case each of gastric epithelial dysplasia and adenocarcinoma showed either complete loss of anti-Lgl2 immunoreactivity or diffuse, mostly weak, cytoplasmic staining.
  • Complete loss of immunoreactivity was significantly more often observed in diffuse-type than in intestinal-type adenocarcinomas (79 vs 48%, respectively).
  • Our data suggest that Lgl2 expression is either aberrantly localized or lost in gastric epithelial dysplasia and adenocarcinoma, whereas it is maintained in reactive gastric mucosa.
  • We propose that Lgl2 may be a potential marker to rule out gastric epithelial dysplasia and adenocarcinoma in diagnostic specimens.

MedlinePlus Health Information. consumer health - Salivary Gland Cancer.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • 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.

  • [Title] The use of p63 as an effective immunomarker in the diagnosis of pulmonary squamous cell carcinomas on de-stained bronchial lavage cytological smears.
  • OBJECTIVES: A diagnosis in pulmonary onco-cytopathology primarily necessitates distinguishing small cell carcinoma (SCLC) from non-small cell carcinoma (NSCLC), which includes squamous cell carcinoma and adenocarcinoma.
  • Lately, p63 antibody has been used for distinguishing squamous cell carcinoma from SCLC and adenocarcinoma.
  • METHODS: A single Papanicolaou-stained conventional smear was de-stained and re-fixed with cold acetone and methanol for immunocytochemical staining with p63 antibody.
  • RESULTS: Out of 100 cases, 21 were cytologically diagnosed as squamous cell carcinoma.
  • Twenty of these showed 2+ or 3+ p63 positivity, whereas one, which was adenocarcinoma on histology, showed 1+ staining.
  • Of seven cases cytologically diagnosed as adenocarcinoma, six showed no p63 staining, whereas one, which was squamous cell carcinoma on histology, showed 1+ staining.
  • The former three were found to be SCLC on histology while the latter was squamous cell carcinoma.
  • The former eight were adenocarcinoma on histology and the latter two were squamous cell carcinoma.
  • The 10 cases that showed 1+ p63 staining were adenocarcinomas (n = 5), squamous cell carcinoma (n = 4) and NSCLC, not otherwise specified (n = 1).
  • Positive staining was seen in normal basal cells, which acted as an internal control.
  • Overall sensitivity of p63 for squamous cell carcinoma was 100% and specificity was 90.4%.
  • CONCLUSIONS: p63 immunostaining on processed cytology smears can be used to help identify squamous cell carcinoma.
  • Its diffuse expression was specific for squamous cell carcinoma while focal staining was also seen in adenocarcinoma.

  • BACKGROUND: The aim of this study was to evaluate the prognostic significance of the basal cell-like molecular breast cancer subtype with respect to locoregional recurrence and distant metastasis in African American women treated for breast cancer.
  • Compared with the other molecular subtypes the basal cell-like subtype showed a statistically significant association to distant metastasis: 15 (42.9%) vs 13 (37.1%), 4 (11.4%), and 3 (8.6%) (P < .001), respectively, for luminal A, Her-2/neu, and luminal B subtypes.
  • The basal cell-like subtype was an independent predictor of distant metastasis (odds ratio, 5.8; 95% confidence interval, 1.5-22.0, P = .009).
  • The molecular subtypes showed no statistically significant difference with respect to locoregional treatment administered and tumor stage at time of diagnosis.
  • CONCLUSIONS: The basal cell-like molecular breast cancer subtype is an independent predictor of distant metastasis in African American women.

  • [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.
  • 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:.
  • (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.

  • The following histologic changes are associated with prostatic carcinomas. prostatic acini are close to one another and present with linear infiltrates in the fibromuscular tissue; cells lining the acini often consist of a single layer, and the basal cell layer is absent; prominent large eosinophilic nucleoli are usually present in malignant cells; nuclear hyperchromatism is rare and it depends on the quality of the tissue fixation; perineural invasion is often observed.
  • Immunohistochemistry is widely used in pathology and clinical diagnosis of prostatic carcinoma, metastases of prostatic origin in staging malignant tumors and in the prognosis.

  • [Title] mRNA expression of minichromosome maintenance 2 in colonic adenoma and adenocarcinoma.
  • Here, we aimed to evaluate the possible value of a proliferation marker, minichromosome maintenance 2 (MCM2), in the early diagnosis of colorectal cancer, by analyzing the difference in MCM2 expression among normal mucosa, adenoma, and adenocarcinoma, and investigating the relationship of MCM2 expression in adenomas with clinicopathologic variables.
  • Using immunohistochemistry and real-time reverse transcription-PCR, we observed that the expression of MCM2 protein was present on basal third to half of colonic crypts in normal mucosa, whereas throughout the epithelium in adenomas and adenocarcinomas, the expression of MCM2 mRNA in adenocarcinomas was significantly higher than in adenomas (P=0.001), whereas the difference between adenoma and normal mucosa was not significant (P=0.184); we also found that the expression of MCM2 mRNA tended to be increased in the adenomas with high-grade dysplasia, or in older patients, respectively, compared with those with low-grade dysplasia, and younger patients.
  • These results suggested the potential value of MCM2 in early diagnosis of colorectal cancer.

  • 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] Terminal respiratory unit type lung adenocarcinoma is associated with distinctive EGFR immunoreactivity and EGFR mutations.
  • Approximately 10% to 20% of nonsmall cell lung cancer patients respond to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors, such as gefitinib.
  • A recent study reported that the terminal respiratory unit (TRU)-type adenocarcinoma shares the clinical profile and EGFR mutations of gefitinib responders.
  • EGFR positivity was seen most frequently in squamous cell carcinomas (77%), followed by TRU-type adenocarcinomas (63%), large cell carcinomas (23%), and non-TRU-type adenocarcinomas (12%).
  • A distinctive basally oriented cytoplasmic positivity was observed exclusively in TRU-type adenocarcinomas.
  • EGFR mutation was identified in 6 of 54 cases studied and all 6 cases were TRU-type adenocarcinomas.
  • Five of six cases with EGFR mutation were positive for EGFR immunostain with the basal cytoplasmic localization.
  • In conclusion, EGFR immunoreactivity with basal cytoplasmic pattern was exclusively seen in TRU-type adenocarcinoma and a subset of these cases was seen with EGFR mutations in the responders to EGFR inhibitor therapy.

  • OBJECTIVE: To investigate the expression differences of minichromosome maintenance 2 (MCM2) mRNA and protein among colon adenocarcinoma, colon adenoma and normal mucosa, and among different clinicopathological types of adenomas.
  • METHODS: Fifty specimens, including 33 colonic adenomas, 12 colonic adenocarcinomas and 5 normal colonic mucosa were selected.
  • Expression differences of MCM2 mRNA among the colonic adenocarcinoma, adenoma and normal colonic mucosa were evaluated by REST-XL software.
  • RESULTS: The expression of MCM2 was observed in the basal third to half of the colonic crypts in normal mucosa, while throughout the epithelium in the colonic adenocarcinomas and adenomas.
  • However, the expression of MCM2 mRNA in the adenocarcinomas was significantly higher than that in the adenomas(P=0.001).
  • CONCLUSION: The difference of MCM2 expression between the adenoma and the adenocarcinoma indicates its potential value in the early diagnosis of colonic cancer.

  • BACKGROUND: The distinction between ocular sebaceous carcinoma, poorly differentiated ocular squamous cell carcinoma and ocular basal cell carcinoma can be challenging.
  • RESULTS: Positive staining for cytokeratin (CK)7 was seen in 100% of sebaceous carcinomas, 77.8% of basal cell carcinomas and 67.7% of squamous cell carcinomas.
  • One hundred percent of sebaceous and basal cell carcinomas were positive for cytokeratin CAM 5.2, while only 83.3% of squamous cell carcinomas were positive.
  • Using epithelial membrane antigen (EMA), 100% of squamous cell carcinomas and 80% of sebaceous carcinomas were positive, while basal cell carcinomas were uniformly negative.
  • One hundred percent of basal cell carcinomas and 80% of sebaceous carcinomas were positive for Ber-EP4, while all squamous cell carcinomas were negative.
  • Finally, 77.8%, 20% and 16.7% of basal cell carcinomas, sebaceous carcinomas and squamous cell carcinomas showed immunoreactivity for the androgen receptor.
  • CONCLUSION: An EMA positive, Ber-EP4 positive immunophenotype supports sebaceous carcinoma, EMA positive, Ber-EP4 negative result supports squamous cell carcinoma and an EMA negative, Ber-EP4 positive result supports basal cell carcinoma.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • To check the diagnosis of "small two- or three-gland carcinoma" we prepared new H and E sections and, when the atypical glands were no longer available, also performed immunohistochemical analyses in 1,041 cases referred to our uropathology consultation service, comparing the diagnoses supplied by the referring doctors with the final diagnoses.
  • In 61.6 of these cases histology confirmed the diagnosis of adenocarcinoma of the prostate; the diagnosis recorded when the basal cell marker was absent and the tumour marker P504S was strongly expressed was atypical microglandular proliferation or suspected carcinoma.

  • Alpha-methylacyl-CoA racemase (AMACR) has recently been shown to be a highly sensitive marker for the diagnosis of prostate cancer.
  • All malignant acini were completely negative for both basal cell markers (34betaE12 and p63).
  • In all cases, basal cells were strongly stained by p63 in benign acini with a mean positive percentage of 96%.
  • Similarly, basal cells in benign acini displayed moderate staining intensities for 34betaE12 in 3 (7%) of 41 cases and strong immunostaining for this marker in the remaining 38 cases (93%); the mean percentage of positive cells was 92%.

  • [Title] The use of immunohistochemistry for diagnosis of prostate cancer.
  • The use of antibodies to mark basal cells is currently a common practice, in order to avoid rebiopsies.
  • There has been no reported study that has reviewed characteristics of radical prostatectomies (RPs) when immunohistochemistry (IHC) was necessary for definitive diagnosis.
  • The results of surgical specimens of 27 patients treated by RP after the diagnosis of prostate cancer (PC) was made using IHC (Group 1) were compared with 1040 patients where IHC was not necessary (Group 2).
  • In Group 1, two (7.4%) adenocarcinomas were insignificant versus 29 (2.9%) for Group 2.
  • CONCLUSION: The use of IHC did not lead to diagnosis of insignificant tumors as illustrated by absence of differences in pathological stage or positive surgical margins in men submitted to RP.

  • [Title] Aberrant diffuse expression of p63 in adenocarcinoma of the prostate on needle biopsy and radical prostatectomy: report of 21 cases.
  • The presence of p63 positive atypical glands with an infiltrative pattern and perineural invasion on radical prostatectomy confirmed the needle biopsy diagnosis of carcinoma.
  • Rarely, prostate cancer can aberrantly express diffuse p63 staining in a nonbasal cell distribution leading to the erroneous diagnosis of atrophy or atypical basal cell proliferation.
  • The diagnosis of prostate cancer is based on the morphology and confirmed by the absence of high molecular weight cytokeratin staining and positivity for alpha-methylacyl-CoA racemase in the atypical glands.
  • Pathologists need to be aware of this rare and unusual phenomenon, which is a potential pitfall in prostate cancer diagnosis.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Partial atrophy on prostate needle biopsy cores: a morphologic and immunohistochemical study.
  • The morphologic features of the 278 cases and immunohistochemistry of 236 cases (198 with prostate cocktail and 38 with only basal cell makers) were analyzed.
  • Of 198 cases with a prostatic cocktail stain, 48 (24.2%) had a cancer pattern for both basal cells and AMACR (p63-, HMWCK-, and AMACR+), 14 (7.1%) had a cancer pattern for basal cells (p63-, HMWCK-, and AMACR-), 89 (44.9%) had a cancer pattern for AMACR (p63+, HMWCK+, and AMACR+), and 47 (23.7%) had a totally benign pattern (p63+, HMWCK+, and AMACR-).
  • Of the 198 cases using the cocktail stain, 136 (68.7%) had positive basal cell staining.
  • The percentage of basal cells labeled with the combination of p63/HMWCK was: <5% in 42 (21.2%) cases, 5% to 75% in 58 (29.3%) cases, and >75% in 36 (18.2%) cases.
  • In conclusion, partial atrophy is a benign mimicker of adenocarcinoma both as a result of its routine morphologic features and its immunohistochemical profile.
  • Recognition of the classic morphology of partial atrophy on routine hematoxylin and eosin-stained sections is critical to avoid misdiagnosing partial atrophy as adenocarcinoma.

  • [Title] Atypical cribriform lesions of the prostate: relationship to prostatic carcinoma and implication for diagnosis in prostate biopsies.
  • Atypical cribriform lesions of the prostate (ACL) are cribriform glands lined by cytologically malignant cells with partial or complete basal cell lining.
  • We report the incidence, topographic relation to cancer, and morphologic differences of these 2 lesions in radical prostatectomy and discuss the potential biologic basis and implication for diagnosis in prostate biopsy.
  • ACL was defined as cribriform glands comprising cytologically malignant cells that spanned the entire glandular lumens with partial or complete basal cell lining confirmed by basal cell immunostaining.
  • However, cribriform HGPIN and IDC-P overlap at the "low grade" architectural and morphologic spectrum and are difficult to distinguish based on morphologic criteria alone.

  • [Title] Desmosomal plakophilins in the prostate and prostatic adenocarcinomas: implications for diagnosis and tumor progression.
  • The plakophilins, members of the armadillo-repeat family, consist of three different proteins (PKP1-3) that are specifically recruited to desmosomal plaques in a highly cell type-specific manner.
  • Using immunofluorescence, immunoelectron microscopy, and immunoblot, we found that all three plakophilins occurred in luminal and basal cells of the pseudostratified prostate epithelium.
  • The analysis of 135 cases of prostatic adenocarcinomas grouped into tumors with low (Gleason score < or = 6), intermediate (Gleason score 7), and high Gleason score (8 < or = Gleason score < or = 10) showed that the expression of PKP1 was reduced or lost in adenocarcinomas with high Gleason scores.
  • The expression of PKP2 was unchanged in all prostatic adenocarcinomas analyzed.
  • In DU 145 cell lines with either overexpression or knockdown of PKP3, both imbalances resulted in fewer desmosomal cell contacts.

  • [Title] Claudin-1 and claudin-5 expression patterns differentiate lung squamous cell carcinomas from adenocarcinomas.
  • We investigated the expression of tight junction proteins in human lung squamous cell carcinomas and adenocarcinomas by immunohistochemistry and quantitative real-time reverse transcription-polymerase chain reaction (RT-PCR).
  • We found a statistically significant correlation between diagnosis and positivity of tumors with either claudin (CLDN)-1 or CLDN-5.
  • Squamous cell carcinomas and basal cells of bronchial epithelium were positive for CLDN-1 and negative for CLDN-5, whereas adenocarcinomas, normal cylindrical cells and pneumocytes were positive for CLDN-5 and negative for CLDN-1, suggesting different pathways in tumor development and progression.
  • CLDN-4 and ZO-1 staining were detected in both types of tumors, whereas cingulin (CGN) was not detected in squamous cell carcinomas.
  • In squamous cell carcinomas, we observed statistically significant decreases in the mRNA levels of JAM-1, occludin, CLDN-3, CLDN-4, CLDN-7, CGN, ZO-2 and ZO-3, and an increase in CLDN-1 mRNA.
  • In adenocarcinomas, when transcript levels were compared with bronchial cells, we observed statistically significant decreases in the mRNA levels of CLDN-1, CLDN-3, CLDN-4, CLDN-7, ZO-2 and ZO-3.

  • [Title] p63 immunohistochemistry differentiates salivary gland oncocytoma and oncocytic carcinoma from metastatic renal cell carcinoma.
  • Metastatic renal cell carcinoma (RCC) can pose diagnostic challenges in the head and neck often resembling benign and malignant oncocytic lesions.
  • Morphologic features evaluated were cytoplasmic character (clear versus oncocytic), Fuhrman nuclear grade, mitotic rate, growth pattern, presence of lumens/blood lakes and stromal characteristics.
  • Tumors were stained with antibodies to p63, renal cell carcinoma marker (RCCm), CD10, and vimentin.
  • Eight benign oncocytic tumors (29%) had clear cell features while 6 metastatic RCC (37%) had oncocytic features.
  • All primary salivary gland tumors were positive for p63, predominately in basal cell-type distribution.
  • While clinical history and morphology usually are adequate, demonstration of p63 staining can definitively exclude metastatic RCC from the differential diagnosis of similar appearing tumors in salivary glands, namely oncocytoma and oncocytic carcinoma, with 100% specificity and sensitivity.

NCI CPTAC Assay Portal. NCI CPTAC Assay Portal .

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] SOX2 is highly expressed in squamous cell carcinomas of the gastrointestinal tract.
  • SOX2 is a high-mobility group box embryonic stem cell transcription factor that is expressed in the developing foregut and normal gastric epithelium and is downregulated in intestinal metaplasia of the stomach and esophagus.
  • In addition, SOX2 colocalizes with p63 in the basal layer and plays a critical role in the maintenance of the stratified squamous epithelium of the esophagus.
  • SOX2 expression in squamous cell carcinomas of the gastrointestinal tract has not been previously evaluated.
  • The purpose of this study was to determine whether SOX2 is differentially expressed in squamous cell carcinomas versus adenocarcinomas of the esophagus and rectum/anal canal and to compare its expression to p63, cytokeratin 5/6, and CDX2.
  • In total, 93 tumors were evaluated: 26 esophageal squamous cell carcinomas, 23 esophageal adenocarcinomas, 21 squamous cell carcinomas of the anal canal, and 23 rectal adenocarcinomas.
  • SOX2 was expressed in 81% of esophageal squamous cell carcinomas and 91% of anal canal squamous cell carcinomas, compared to 13% and 17% of esophageal and rectal adenocarcinomas, respectively. p63 was expressed in 96% of esophageal squamous cell carcinomas and 100% of anal canal squamous cell carcinomas; the single squamous cell carcinoma negative for p63 was strongly positive for SOX2.
  • Cytokeratin 5/6 was expressed in most esophageal and anal canal squamous cell carcinomas, but was also positive in 43% of esophageal adenocarcinomas and 13% of rectal adenocarcinomas.
  • In summary, SOX2 is preferentially expressed in squamous cell carcinomas of the esophagus and anal canal compared to adenocarcinomas from these sites.
  • SOX2 may be useful in an immunohistochemical panel to differentiate between squamous cell carcinomas and adenocarcinomas of the gastrointestinal tract.

NCI CPTC Antibody Characterization Program. NCI CPTC Antibody Characterization Program .

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • RESULTS: Maspin and GST-pi were strongly and consistently coexpressed in the cytoplasm of basal cells of normal prostatic glands, whereas normal luminal cells were inconsistently weakly positive.
  • Prostatic adenocarcinomas overexpressed maspin in 27/34 cases (79%).
  • CONCLUSION: Consistent coexpression of maspin and GST-pi was observed in basal cells of the prostatic glands, which could be used as an additional immunohistochemical test in the evaluation of prostatic malignancy.
  • Prostatic adenocarcinomas express maspin in an aberrant nuclear distribution without coexpresion of GST-pi.
  • These results indicate a deregulation of expression of maspin and GST-pi in prostatic adenocarcinomas.

91. Takamura H, Yamashita H: Clinicopathological analysis of malignant eyelid tumor cases at Yamagata university hospital: statistical comparison of tumor incidence in Japan and in other countries. Jpn J Ophthalmol; 2005 Sep-Oct;49(5):349-54

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • RESULTS: Data from our clinic: Among the total of 38 cases, 15 cases (39.5%) were diagnosed as basal cell carcinoma, 11 cases (28.9%) as sebaceous gland carcinoma, and 4 cases (10.5%) as squamous cell carcinoma.
  • In addition, three cases were malignant melanoma, two adenocarcinoma, one Merkel cell carcinoma, one malignant peripheral nerve sheath tumor, and one malignant lymphoma.
  • The prognosis of the cases with basal cell carcinoma and squamous cell carcinoma was good, and that of the other tumors was relatively poor.
  • During the same period, in Caucasians, basal cell carcinoma constituted about 80%-90% of the malignant eyelid tumors, whereas in Japan and Asian countries, basal cell carcinoma, sebaceous gland carcinoma, and squamous cell carcinoma each constituted about 20%-40%.
  • CONCLUSIONS: A racial difference in the incidence of basal cell carcinoma, sebaceous gland carcinoma, and squamous cell carcinoma can be considered in making a diagnosis.

  • [Title] Deep-seated rectal/anal basaloid carcinoma: useful immunocytochemistry in rare squamous cell carcinoma variants.
  • OBJECTIVES: To report the cytological aspects of ano-rectal basaloid carcinoma (BC) variant in endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) conventional and liquid-based cytology (LBC), in a series of 10 cases of deep-seated squamous cell carcinomas (SCC), and to discuss the diagnostic difficulties in interpreting the morphology and immunocytochemical findings.
  • Of these two cases, only one was correctly diagnosed by EUS-FNA specimen, whereas in the second case, the initial cytological diagnosis was poorly differentiated adenocarcinoma and the final diagnosis of basaloid carcinoma variant was established on surgical resection.
  • Immunocytochemistry (ICC) using CK7, CK20 and CK34betae12 on FNA specimens confirmed the diagnosis retrospectively.
  • CONCLUSION: The diagnosis of basaloid variant of SCC in a rectal location can be very difficult, both on account of the uncommon location and because of the low specificity of morphological aspects on EUS-FNA smears.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • We further examined the effects of age, period of diagnosis, and birth cohort on incidence trends using age-period-cohort analysis.
  • RESULTS: The mean age at diagnosis of eyelid cancers was 62.6+/-14.1 years.
  • The most common eyelid malignancy was basal cell carcinoma (BCC; 65.1%), followed by squamous cell carcinoma (12.6%), and sebaceous cell carcinoma (7.9%).
  • Basal cell carcinoma dominates the incidence trends, and the significant cohort effects give a warning of increasing risk of BCC in younger birth cohorts.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • BACKGROUND: Sebaceous carcinoma of the eyelid can clinically mimic benign conditions, such as recurrent chalazion and inflammation and histopathologically squamous cell and basal cell carcinoma (BCC).
  • This retrospective study was undertaken as an attempt to improve the characterization and consequently the diagnosis of these tumors.
  • Of these, 75% had features similar to squamous cell carcinoma (SqCC), some with dyskeratosis (30%) and 7% resembled BCC.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • We reviewed the Memorial Sloan-Kettering Cancer Center experience with these tumors to better understand their histology, time to diagnosis, treatment, and outcome.
  • PROCEDURE: A retrospective review was performed on all patients 21 years of age or younger at diagnosis, treated for primary epithelial lung malignancies at Memorial Sloan-Kettering Cancer Center between 1980 and 2001.
  • The median age at diagnosis was 19 (range: 12-21) years.
  • The most common radiographic abnormality was a mass (55%) on chest imaging.
  • Seven patients (64%) were initially diagnosed as having pneumonia which contributed to a delay in diagnosis.
  • Final pathologic diagnoses included adenocarcinoma (four), carcinoid tumor (three typical, one atypical), basaloid carcinoma (two), and mucoepidermoid carcinoma (one).
  • CONCLUSIONS: When children and adolescents present with primary epithelial lung malignancy a majority will have advanced disease and experience a delay in diagnosis.
  • Patients with carcinoid tumors seem to have the best prognosis, followed by adenocarcinoma.

  • [Title] A panel of 3 markers including p16, ProExC, or HPV ISH is optimal for distinguishing between primary endometrial and endocervical adenocarcinomas.
  • Endometrial and endocervical adenocarcinomas may seem histologically identical and it can be difficult to determine primary site of origin based on morphology alone.
  • The TMA consisted of 214 endometrial carcinomas, 33 endocervical adenocarcinomas, and 36 problematic cases.
  • The endometrial and endocervical carcinomas represented usual endometrioid and mucinous types, and special variants (uterine serous carcinoma, uterine clear cell carcinoma, minimal deviation endocervical adenocarcinoma, cervical small cell carcinoma, adenoid basal cell carcinoma, mesonephric carcinoma).
  • Using a script written in R, the diagnostic accuracy of all possible combinations of markers was evaluated and it was shown that a 3 marker panel including vimentin, ER, or PR, and an HPV marker (p16, ProExC, or HPV ISH) is optimal for determining site of origin for usual endometrial and endocervical adenocarcinomas.

  • [Title] Identification of cell-of-origin breast tumor subtypes in inflammatory breast cancer by gene expression profiling.
  • Most patients have lymph node involvement at the time of diagnosis and 1/3 of the patients have distant metastases.
  • We identified the same cell-of-origin subtypes in IBC as those already described in non-IBC.
  • The robustness of this classification was assessed by an unsupervised hierarchical clustering with an alternative gene set of 141 genes related to the cell-of-origin subtypes, selected using a discriminating score and iterative random permutation testing.
  • The contribution of the different cell-of-origin subtypes to the IBC phenotype was investigated by principal component analysis.
  • Generally, the combined ErbB2-overexpressing and basal-like cluster was more expressed in IBC compared to non-IBC, whereas the combined luminal A, luminal B and normal-like cluster was more pronounced in non-IBC compared to IBC.
  • The presence of the same molecular cell-of-origin subtypes in IBC as in non-IBC does not exclude the specific molecular nature of IBC, since gene lists that characterize IBC and non-IBC are entirely different from gene lists that define the different cell-of-origin subtypes, as evidenced by principal component analysis.
