title: Carcinoid tumor of the extrahepatic bile duct: report of a case.
abstract: We report a rare case of carcinoid tumor of the extrahepatic bile duct. A 69-year-old woman with a history of hyperthyroidism was diagnosed to have a tumor of the extrahepatic bile duct. Laparotomy, for presumed cholangiocarcinoma, revealed a 2.5-cm-long, firm mass of the hilar-upper bile duct. The extrahepatic bile duct resection and lymphadenectomy was performed. Her postoperative course was uneventful and has been asymptomatic without recurrent tumor during 2 years of follow-up. Primary carcinoid tumors of the extrahepatic bile duct are very rare. Herein we report this rare case with a review of the literature.
