title: Pigment polyp in the common bile duct.
abstract: We report here a case of a young female with sickle cell disease and a past history of open cholecystectomy 10 years ago presenting with intermittent upper abdominal pain and jaundice. Abdominal ultrasonography revealed a dilated biliary tree with the possibility of a stone in the proximal common bile duct, but cholangiopancreatography showed a polypoid lesion at the junction of the common hepatic and common bile ducts. Biopsy of the lesion was benign. She underwent bile duct exploration and excision of what proved to be a  pigment'polyp arising from the cystic duct stump. This is the first reported case of a pigment polyp encountered in sickle a cell disease population.
