Germ cell tumor markers may be usefu Glypican-3 is a good marker for both well-differentiated and poorly differentiated HCC, with a diagnostic sensitivity of approximately 85%. 80 In addition, glypican-3 is not expressed in benign or reactive hepatocytes; in contrast, both ARG1 and HepPar-1 are expressed in both benign and neoplastic hepatocytes. Both CD10 and polyclonal CEA. Glypican-1 expression was related to promote angiogenesis, metastasis, cell division, and perineural invasion of pancreatic cancer cells 15 and has been reported as possible prognostic marker of.

Although GATA3 has been recognized as a useful marker for mammary and urothelial carcinomas, there is large variation in GATA3 expression detected in pheochromocytoma (PC) and paraganglioma (PGL), from 90% to less than 5%. For GATA3 to be a useful diagnostic marker for PCCs/PGLs, the reasons for such discrepancy must be elucidated. Thus, we compared different immunohistochemistry protocols This article outlines the pathway for processing liver tumour tissue in the histopathology laboratory, before discussing the pathological features of the more commonly encountered benign and malignant liver tumours. The non-sampled tissue is destroyed soon after the pathology report has been authorized. glutamine synthetase and glypican. First, glypican 3 (GPC3), a membrane-bound proteoglycan and oncofetal antigen whose expression is most often used in diagnostic pathology to support an interpretation of hepatocellular carcinoma (HCC), was identified as a potential tumor suppressor in gene expression profiling of lung tumors, 3, 4 and was subsequently found to be overexpressed. Glypican-3 shows strong positive cytoplasmic staining in more than 95% of yolk sac tumors, and it has emerged as an additional positive confirmatory stain for the diagnosis. 394 Glypican-3 rarely stains clear cell carcinoma, but, like AFP, it is positive in tumors with hepatoid features, including hepatoid yolk sac tumor, hepatoid carcinoma. Malignant mixed Mullerian tumor (MMMT) is an uncommon aggressive neoplasm composed of both malignant epithelial and mesenchymal components. In this study, immunohistochemical stains of germ cell markers, including SALL4, OCT3/4, glypican-3, and alpha-fetal protein (AFP), and CDX2 were performed in a series of MMMTs. SALL4 nuclear immunoreactivity was detected in 6 out of 19 cases (33%)

Glypican‐3 (GPC3) is a novel serological and immunohistochemical marker of hepatocellular carcinoma. 17-19 A recent study to examine GPC3 immunoreactivity in combined HCC‐CC shows the expression is sensitive and specific to the HCC component of combined HCC‐CC but few cases also show weak immunoreactivity in the cholangiocarcinoma. Glypican 3 (GPC3) marks moderately and poorly differ-entiated HCC, including scirrhous HCC, but not normal liver or benign hepatic neoplasms (Fig. 4).8 In one study of cell block materials, most HCCs (including all poorly differentiated ones) stained with GPC3, but 83.3% of metastatic adenocarcinomas were negative.9 Rare nonhe

Epidemiologic studies report the prevalence of HCA is approximately 3-4 cases per 100,000 people in Europe and North America, [] and lower in Asian countries [].The highest prevalence is described in females taking oral contraceptives, but other risk factors, such as anabolic.

Specifically, GPC 3 stained all cases (24/24) of yolk sac tumor, and typically in a strong fashion. Additionally, 7 of 7 cases of chorio-carcinoma were GPC 3 positive, where it stained th Prior studies suggested that detection of albumin messenger RNA (mRNA) expression by RNA in situ hybridization (RNA ISH) is a highly sensitive method for identification of hepatocellular carcinomas (HCCs) and intrahepatic cholangiocarcinomas (ICCs)/hepatoid carcinomas, with a diagnostic sensitivity of nearly 100% for HCCs and a range of 45% to 99% for ICCs. 1-5 Ferrone et al 2 reported that. The ability to distinguish hepatocellular carcinoma (HCC) from metastatic carcinoma (MC) involving the liver and cholangiocarcinoma (CC) by immunohistochemistry has been limited by the lack of a reliable positive marker for hepatocellular differentiation. Arginase-1 is a marker for HCC recently described in some literature. To examine the immunohistochemical staining of arginase-1 in cases of. Furthermore, extra caution is needed for interpreting unexpected glypican 3 positivity associated with significantly inflamed benign hepatocytes, 64 macroregenerative nodules, and DNs. 62 A third problematic issue with glypican 3 immunostaining is that the labeling can be very patchy, especially when dealing with needle biopsy specimens, as up.

  1. Partial atrophy is the most common benign mimicker of prostate cancer on needle biopsy. Of 3916 prostate needle core biopsy cases received in our consultation service over a period of 3 months (March 1, 2007 to May 31, 2007), 170 cases (4.3%) with partial atrophy were diagnosed as atypical glands by outside pathologists and prospectively identified. We supplemented our material with 108 cases.

By Rodney T. Miller, M.D., Director of Immunohistochemistry Germ cell neoplasms can show a bewildering array of appearances, and there may be significant morphologic overlap among subtypes. For this reason, Immunohistochemistry is often performed to assist in accurately assessing the types and extent of germ cell elements present within a tumor. This month, we discuss our current approac Immunohistochemistry (IHC) is commonly used in the diagnosis of gastrointestinal (GI) and liver neoplasms to facilitate accurate tumor classification. 1-4 There are two practical goals: One is to confirm a tumor diagnosis by excluding morphologic mimickers or to identify the most reasonable tissue or organ of origin in cases of metastatic carcinoma of unknown primary. 5,6 The other is to. 7.3.

Heparan sulfate (HS) is a linear polysaccharide found in all animal tissues. It occurs as a proteoglycan (HSPG, i.e. Heparan Sulfate ProteoGlycan) in which two or three HS chains are attached in close proximity to cell surface or extracellular matrix proteins. It is in this form that HS binds to a variety of protein ligands, including Wnt, and regulates a wide range of biological activities. Immunohistochemically, iCC usually does not express specific hepatocytic markers as AFP, glypican-3, CK8 and 18, BSEP or MDR3 (commonly expressed by HCC) with a few exceptions for HepPar1 and arginase 1 , but may rather frequently express, at a mild level, albumin mRNA, while, unlike HCC, it shows diffuse cytoplasmic labeling with polyclonal.

The neoplastic cells show expression of the expected hepatocellular cytokeratin 8 and 18 , but also are strongly positive for cytokeratin 7 [35, 68, 83-86] and occasionally (between 5 and 25%) for cytokeratin 19 [35, 68, 83, 84].

The retroperitoneum and thigh represent the most common anatomic locations for both the sarcomas. Despite their morphologic similarity, the issue of whether these 2 sarcomas share overlapping immunohistochemical and molecular features has not been well studied. We examined the expression of the lipogenic tumor-related markers. Two recent reviews summarized important diagnostic pitfalls and workup recommendations in testicular pathology in 2008 and 2010, respectively. (4,5) In this article, we will revisit some of these problems, as well as discuss some new ones, and incorporate additional information, including the application of recent immunomarkers, to these. Yolk sac tumor (endodermal sinus tumor) is a rare malignant germ cell tumor arising in the testis or ovary. Extragonadal yolk sac tumor is even rarer and has only been described in case reports. Due to the rarity of the tumors, the appropriately optimal treatment remains unclear. We report a case of yolk sac tumor in the seminal vesicle.
