Abstract
- Biliary Papillomatosis is an extremely rare pathologic entity. Only about 40 cases of intrahepatic or diffuse intra- and extrahepatic papillomatosis have been described since the first report in 1959 by Caroli. Although this is a histologically benign lesion, its course is unfavaurable because of its tendency to extend to the entire biliary tract, high recurrence rate following local excision and the probability of progression to malignancy. We described herein a case of biliary papillomatosis associated with diffuse bile duct dilatation. The patient, a 59-year-old male, was admitted to our hospital because of right upper abdominal pain and weight loss. Cholangiogram revealed multiple round filling defects in common hepatic duct with intrahepatic bile duct dilatation. The patient underwent Whipple's operation with right lobectomy. Grossly, multiple small pin-head sized polypoid masses were seen in common bile duct, common hepatic duct and right intrahepatic duct. Microscapically, papillary epithelial hyperplasia with moderate cellular atypia was seen and there was no evidence of stromal invasion. He is healthy with a follow-up for 7 months.
