The paraganglia demonstrated characteristic histology, and immunohistochemistry was supportive when enough tissue was available. These cells can be focally detected by immunohistochemistry (IHC) with markers such as chromogranin and … Therefore in the present study we aimed to evaluate the ERG expression in prostatic acinar adenocarcinoma and its association with clinicopathological features. The diagnosis of prostatic adenocarcinoma on histopathology depends on architectural and cytomorphological features supported by immunohistochemistry (IHC). Immunohistochemical demonstration of PSA and other prostate markers and negative thrombomodulin and GATA3 staining in prostatic duct adenocarcinoma can also be of help. Immunohistochemical expression of prostatic antigens in adenocarcinoma and villous adenoma of the urinary bladder. However PSA immunohistochemistry does not distinguish between benign and malignant processes, but helps in identifying prostatic origin of metastatic tumors except adenocarcinoma [12]. Most prostate cancers are classified as adenocarcinomas, or glandular cancers, that begin when semen-secreting gland cells mutate into cancer cells.The region of the prostate gland where the adenocarcinoma is most common is the peripheral zone. We performed an immunohistochemical study of select sections from 93 radical prostatectomies performed at the Mayo Clinic between 1987 and 1991. Immunohistochemistry in Prostate Cancer The use of IHC as an auxiliary in the diagnosis of adenocarcinoma is a common practice in uropathology, and the use of antibodies against p63 and high molecular weight cytokeratin has been recommended as adjuncts in confirming prostatic carcinoma … The authors performed an immunohistochemical study of represen- By Nazia Hussain. Here we use immunohistochemistry to evaluate EBP50’s expression in normal donor prostate (NDP), benign prostatic hyperplasia (BPH), high grade prostatic intraepithelial neoplasia (HGPIN), normal tissue adjacent to prostatic adenocarcinoma (NAC), primary prostatic adenocarcinoma (PCa), and metastatic prostatic adenocarcinoma (Mets). Ductal cases accounted for 7% of the total prostate adenocarcinomas, whereas the remaining 93% were acinar tumors. It is the most common malignant tumor among men.

Diagnostic utility of immunohistochemical staining for p63, a sensitive marker of prostatic basal cells. The morphologic features characteristic of the disease's pathology include small tumor cells with minimal cytoplasm, nuclear molding, fine chromatin pattern, extensive tumor necrosis/apoptosis, and a brisk mitotic rate. A prostatic biopsy revealed a moderately differentiated acinar prostatic adenocarcinoma with a Gleason's score of 9 (4+5)/10. Get PDF (14 MB) Abstract. Status of androgen receptor (AR) in prostate carcinoma is biologically important. Specimens from 37 radical prostatectomies, performed for prostatic adenocarcinoma at the Yale-New Haven Hospital (New Haven, Connecticut, USA), were included in this study according to a protocol approved by Yale University School of Medicine Review Board. In part, technical factors, including the quality of the biopsies, the tissue processing, and histopathological reporting, may account for these differences. Ductal adenocarcinoma of the prostate gland, also prostatic ductal adenocarcinoma, is relatively common variant of prostate cancer. Immunohistochemistry of Prostatic lesions 1. Abstract: As the most frequent malignant histological subtype in prostatic cancer, prostatic acinar adenocarcinoma (PAA) has a series of benign mimickers including prostatic or non-prostatic lesions and normal structures, which may lead to an erroneous diagnosis and inappropriate treatment. This paper. KW - prostatectomy.

Profile 77:1242-1250, 2017 Google Scholar: 8. We searched the literature for published gene-lists of differentially expressed genes between NEPC and prostatic adenocarcinoma based on expression profiling of patient tumor samples or patient-derived xenografts (Table 1) [4, 8, 11,12,13,14,15].To compare gene-lists and identify common genes, we updated gene names and probe assignments with … IHC is used for diagnosis from prostate biopsy, though this remains controversial as to the precision and accuracy of the current biomarkers used in this test and many are looking for alternative specific and sensitive prostate cancer biomarkers to improve outcomes. Histology confirmed the presence of metastatic moderately well differentiated prostatic adenocarcinoma (Figure 1) extending through the length of the penis and into the glans and spreading to the surface of the skin at the corona with vascular and lymphatic permeation. Prostatic adenocarcinoma is one of the most common malignancies in males. METHODS. Small cell carcinoma of the prostate is a high-grade malignant neoplasm with neuroendocrine differentiation. Basal cell markers, such as the 34betaE12 antibody and antibodies directed against cytokeratin 5 and 6 or p63, are very useful for demonstration of basal cells as their presence argues against a diagnosis of invasive prostatic carcinoma (PC). Prostate cancer is a major public health concern. The regular full section slides and TMA slides were subject to IHC stain of ERG and FLI1 (Santa Cruz, SC-113).
