title: Intrahepatic and extrahepatic biliary papillomatosis.
abstract: We report a case of biliary papillomatosis that occurred 8 years after resection of a bile duct tumor. In 1982, a 63-year-old man underwent a cholecystectomy because of cholelithiasis. At operation, a solitary tumor was found in the left intrahepatic bile duct, and a lateral hepatic segmentectomy was performed. The tumor was diagnosed as a benign papillary adenoma. In 1990, mild liver dysfunction was revealed in a routine medical examination. Ultrasonography and computed tomography showed a solid tumor measuring approximately 6 cm in diameter in the left hepatic duct. There was no appearance of jaundice during the course. In 1991, a partial hepatic resection and a bile duct resection were performed. At operation, two tumors were found and removed. These tumors were essentially the same as the bile duct tumor resected 8 years ago. They were diagnosed as biliary papillomatosis.
