Abstract
A 45-year-old male patient received cholecystectomy by his private doctor for cholelithiasis and chronic cholecystitis in Feb., 2002. The bile duct was injured during the procedure and it was repaired by simple suturing. The patient had been doing uneventfully until Aug., 2007, when he started to notice general malaise and jaundice and came to the medical department of our hospital. CT study revealed dilatation of the intrahepatic bile duct, stenosis of the mid bile duct and a mass of 10mm in size with enhanced image in the common bile duct. With suspicion of cancer of the bile duct, excision of the bile duct and choledochojejunostomy was performed. An extramural tumor of approximately 10mm in size was found and its pathohistological study revealed a neuroma arising from excised edge of the bile duct. The patient was discharged on the 13th postoperative day without any complication. He is presently doing well. Neuroma arising from edge of the bile duct causing stenosis is difficult to differentiate from carcinoma of the bile duct. In case of ductal stenosis after a biliary surgery, a possibility of this type of pathology should be kept in mind.
