Abstract
Neuroendocrine tumors (NETs) are mostly found in the gastrointestinal tract and the pancreas. The World Health Organization (WHO) classification (2010) has been widely used to categorize NETs [1]. In the digestive system, NETs including those found within the bile ducts, are classed as NET G1 (carcinoid, mitotic count of 20 per 10 HPF and/or >20% Ki-67 index), and mixed adenoneuroendocrine carcinoma (MANEC) [1]. NETs arising from the bile duct are rare, accounting for only 1.8% of gastroenteropancreatic NETs [2]. MANECs of the common bile ducts (CBDs) are extremely rare, and only a few cases have been reported thus far [3-5].
In this study, we report a case of MANEC arising from the mid CBD.
