Cystadenoma of the common bile duct demonstrated by endoscopic retrograde cholangiography: an uncommon cause of extrahepatic obstruction

Abstract

Obstructive jaundice may rarely be caused by a benign tumor of the biliary tract. We describe a patient in whom the diagnosis of cystadenoma of the common bile duct was established. Complete resection of the tumor could be carried out. The clinical, radiological, and histological features of this neoplasm are reviewed.
