Abstract
Neuroendocrine neoplasms (NENs) are heterogeneous tumors with a common phenotype. There are two fundamentally different groups of NENs: well differentiated with a low proliferative index, called neuroendocrine tumors (NETs) and poorly differentiated with a high proliferative index, called neuroendocrine carcinoma (NEC). Extrahepatic bile duct NETs (EBNETs) account for 0.2% to 2% of all gastrointestinal NETs and up to 2% of all malignant neoplasms of the extrahepatic bile ducts. To date, 114 cases of EBNETs have been described, with disease-free survival ranging from 2 to 240 months. In most cases, the tumors expressed Chromogranin A, Synaptophysin, CD56, and NSE. This report presents a rare case of an EBNET in a 61-year-old patient following resection of the extrahepatic bile ducts. The description includes data from radiological and ultrasound diagnostic methods, macro- and microscopic characteristics of the tumor, and immunohistochemical profile.
期刊介绍：
The journal deals with original investigations on pressing problems of general pathology and pathologic anatomy, newest research methods, major issues of the theory and practice as well as problems of experimental, comparative and geographic pathology. To inform readers latest achievements of Russian and foreign medicine the journal regularly publishes editorial and survey articles, reviews of the most interesting Russian and foreign books on pathologic anatomy, new data on modern methods of investigation (histochemistry, electron microscopy, autoradiography, etc.), about problems of teaching, articles on the history of pathological anatomy development both in Russia and abroad.
