Intraductal tubular neoplasm of the common bile duct.

Recently, biliary neoplasms resembling intraductal neoplasms of the pancreas have been documented. In this report, a rare case of intraductal tubular neoplasm (ITN) arising in the common bile duct is presented. A polypoid mass, 10 mm in diameter, was found in a 67-year-old woman in the intrapancreatic part of the common bile duct during the follow up to cholecystolithiasis and choledocholithiasis.
