Abstract

Adenomas of the bile ducts are rare and unusual causes of bile duct obstruction. In Korea, 1 case of papillary adenoma, 5 cases of villous adenoma, 10 cases of biliary papillomatosis, and 1 case of tubulovillous adenoma have been reported. Preoperative diagnosis for these lesions is difficult to render as they can often mimic biliary stones. A case of bile duct tubulovillous adenoma with high grade epithelial dysplasia in a 65-year-old man, is herein reported. It was difficult to diagnose because of coexisting biliary stones. In addition, confusing classification and terminology of bile duct adenomas were reviewed.
