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.<\/jats:p>","DOI":"10.17116\/patol20258701141","type":"journal-article","created":{"date-parts":[[2025,2,12]],"date-time":"2025-02-12T15:57:17Z","timestamp":1739375837000},"page":"41","source":"Crossref","is-referenced-by-count":1,"title":["Neuroendocrine tumor of the extrahepatic bile ducts.
