Carcinoid tumors of the extrahepatic bile duct: A rare cause of malignant biliary obstruction
Carcinoid tumor of the bile duct is a rare form of malignant biliary obstruction. Unlike cholangiocarcinoma, biliary carcinoids occur more commonly in younger patients and in women. Aggressive local invasion by the primary tumor is rare, and metastases occur in less than one-third of patients. All patients who underwent a curative surgical resection were alive and disease free at time of published report, implying a more favorable prognosis. Aggressive surgical resection is recommended.
