title: Case report: two cases of biliary papillomatosis with unusual associations.
abstract: Papillomatosis arising from the biliary tree is a well recognized but rare entity. We encountered two patients with this condition. However, one of them had associated hepatocellular carcinoma and cirrhosis and the other had concomitant recurrent pyogenic cholangitis. To our knowledge, these associations have not been reported before. We, therefore, present these clinical problems and highlight the added difficulty in the management of these patients.
