Context.— Immunohistochemistry has become a useful ancillary study in the identification and classification of pancreatic neoplasms. The diagnostic accuracy has been significantly improved because of the continuous discoveries of tumor-associated biomarkers and the development of effective immunohistochemical panels. Objectives.— To identify and classify pancreatic neoplasms by immunohistochemistry. Data Sources.— Literature review and authors' research data and personal practice experience were used. Conclusions.— To better guide therapeutic decisions and predict the prognostic outcome, it is crucial to make an accurate diagnosis of a pancreatic neoplasm. Application of appropriate immunohistochemical panels enables pathologists to differentiate pancreaticobiliary adenocarcinomas from reactive conditions and to identify rare types of pancreatic neoplasms. Knowing the utilities and pitfalls of each tumor-associated biomarker is essential to avoiding a potential diagnostic error because an absolutely cance...

Summary Distinction between primary intrahepatic cholangiocarcinoma (ICC) and metastatic pancreatic ductal adenocarcinoma (PDA) on a liver biopsy is essentially impossible histologically but has important clinical implications. In this study, 41 ICCs and 60 PDAs were immunohistochemically evaluated for the expression of S100P, pVHL, IMP3, maspin, MUC5AC, and CK17 proteins. The results showed pVHL expression in 29 (71%) ICCs but in only 3 (5%) PDAs. S100P, MUC5AC, and CK17 were frequently express...

Aims Annexin A10 (ANXA10) is a calcium- and phospholipid-binding protein expressed normally in the gastric mucosa. In this study, we evaluated the potential use of ANXA10 as a diagnostic marker. Methods and results We observed ANXA10 expression in the gastric mucosa, the Brunner gland of the duodenum and the urothelium, but absence of expression in other normal organs. Following the screening of 1327 primary carcinomas of major organs, we identified ANXA10 expression in 46% of gastric, 72% of am...

Claudin-4 (CL-4) is a tight junction–associated protein that is expressed in most epithelial cells but absent in mesothelial cells. The purpose of this study is to evaluate the utility of CL-4 immunostaining for assisting in the differential diagnosis of mesothelioma. Sixty mesotheliomas (40 epithelioid, 10 biphasic, and 10 sarcomatoid), 185 carcinomas of different origins that can potentially be confused with mesotheliomas, 37 soft-tissue sarcomas, and 5 melanomas were investigated for CL-4 exp...

Summary Our recent study demonstrated the up-regulation of maspin, IMP3, and S100P and down-regulation of von Hippel-Lindau gene product (pVHL) in ductal adenocarcinoma of the pancreas. Distinction of adenocarcinoma of the gallbladder from benign/reactive glandular epithelium can be challenging if based on hematoxylin and eosin–stained sections alone. Immunohistochemical stains for pVHL, maspin, IMP3, and S100P were performed on 82 gallbladder specimens, including adenocarcinoma (n = 33) and nor...

Summary Glypican-3 (GPC3) is a plasma membrane–bound proteoglycan that can be overexpressed in certain malignancies but has been particularly linked to hepatocellular carcinoma (HCC). GPC3 is currently used as an immunohistochemical marker for HCC, but its expression in epithelial neoplasms of the gastrointestinal (GI) tract and pancreas, a common source of liver metastasis, has not been studied in detail. In this study, we examined GPC3 immunoreactivity in 98 neoplasms of the GI tract including...

The human insulin gene enhancer-binding protein islet-1 (ISL1) is a transcription factor involved in the differentiation of the neuroendocrine pancreatic cells. Recent studies identified ISL1 as a marker for pancreatic well-differentiated neuroendocrine neoplasms. However, little is known about ISL1 expression in pancreatic poorly differentiated and in extrapancreatic well and poorly differentiated neuroendocrine neoplasms. We studied the immunohistochemical expression of ISL1 in 124 neuroendocr...

Acinar cell carcinomas (ACCs) of the pancreas are characterized by the histological and immunohistochemical features of acinar cell differentiation. Recently, BCL10, originally identified as a recurrent t(1;14)(p22;q32) translocation in MALT B-cell lymphoma, was found to be immunohistochemically positive in some solid tumors, including ACC. To evaluate its diagnostic efficacy, we performed BCL10 immunohistochemistry and evaluated molecular markers correlated to pancreatic tumor lineages (neuroen...

Pseudopapillary tumor (SPT) is a rare primary pancreatic neoplasm of uncertain origin and low malignant potential that typically affects young females, mostly in their third decade of life. There are only a few reports on fine needle aspiration (FNA) cytology diagnosis of this neoplasm. We report one such case which was diagnosed based on cytomorphologic and immunocytochemical features on endoscopic ultrasound (EUS) guided FNA smears. A 24-year-old woman presented to the gastroenterology clinic ...

Cytological specimens, which are obtained by minimally invasive methods, are an excellent source of diagnostic material. Sometimes they are the only material available for diagnosis as well as for prognostic/predictive markers. When cytomorphology is not straightforward, ancillary tests may be required for a definitive diagnosis to guide clinical management. Immunocytochemistry (ICC) is the most common and practical ancillary tool used to reach a diagnosis when cytomorphology is equivocal, to di...

Abstract Pancreatic ductal adenocarcinoma is aggressive, with an overall five-year survival rate of 9%, and few patients are candidates for pancreatectomy at presentation. The role of neoadjuvant therapy (NAT) is evolving, especially for high-risk potentially resectable tumors. Due to the increasing number of NAT resection specimens, we aim to characterize the histologic changes associated with NAT, and to compare two tumor regression grading schemes. 118 resections for pancreatic ductal adenoca...

Neoadjuvant systemic treatment is increasingly being integrated in the standard treatment of pancreatic ductal adenocarcinoma (PDAC) patients to improve oncological outcomes. Current available imaging techniques remain unreliable in assessing response to therapies, as they cannot distinguish between (vital) tumor tissue and therapy induced fibrosis (TIF). Consequently, resections with tumor positive margins and subsequent early post-operative recurrences occur and patients eligible for potential...

Serous cystadenoma (SCA) is an uncommon benign pancreatic neoplasm that is most often managed conservatively with follow-up rather than surgical excision. Therefore, to avoid the serious complications of pancreatic surgery, SCA should be diagnosed accurately at the preoperative level. Preoperative SCA diagnosis requires a multimodal diagnostic approach that includes imaging, cystic fluid biochemical analysis and/or endoscopic ultrasound fine-needle aspiration (EUS-FNA). In this brief report, we ...

Body cavity effusions refer to excess fluid that accumulates in the peritoneal, pleural, or pericardial cavity. Body cavity washings often include intraoperative peritoneal or pelvic washings. Cytologic evaluation of body cavity fluids plays an important role in the detection of metastatic diseases, as well as primary body cavity-based lesions. It is crucial to distinguish malignant from benign effusions/washings as the presence of malignant cells may affect diagnosis and staging of malignancies...
