When amputation neuroma causes biliary stricture, it is difficult to distinguish it from bile duct cancer. A case of amputation neuroma of the right hepatic duct after cholecystectomy is reported. A 68-year-old woman was hospitalized with complaints of back pain. She had undergone cholecystectomy 13 years previously. She was diagnosed as having bile duct cancer because percutaneous transhepatic cholangiography revealed obstruction of the right hepatic duct. We performed extended right lobectomy. Histological examination revealed amputation neuroma in the obstructive portion as a result of the previous cholecystectomy. Analysis of 27 cases reported in Japan indicated that cases of stricture of the bile duct with jaundice were difficult to distinguish from bile duct cancer. A detailed past history, cholangioscopy and intraoperative histological examination will lead to accurate diagnosis, and resection of the bile duct with the tumor is standard therapy.
