ABSTRACT
A woman in her 50s was referred due to a solid mass in the head of the pancreas. It was diagnosed as a neuroendocrine carcinoma (NEC) by endoscopic ultrasound-guided fine-needle aspiration. Consequently, pancreatoduodenectomy was performed. A well-differentiated adenocarcinoma component was revealed in the resected bile duct, suggesting a relationship with the NEC component in the pancreas. Genetic examination suggested that cholangiocarcinoma, but not coexisting carcinoma, was converted to NEC after the interstitial invasion. Finally, it was diagnosed as the NEC derived from the extrahepatic bile duct, which is rare at about 0.2-2% in gastrointestinal neuroendocrine neoplasms.
