Abstract
- Bile duct adenomas are discovered incidentally during surgery or at autopsy. Especially, the occurrence of an adenoma in a choledochal cyst is very rare. Biliary carcinomas are known to be related to choledochal cysts. The association of an adenoma in a choledochal cyst with the carcinoma is not definite. We have experienced a case of a tubular adenoma arising in a choledochal cyst. Recently, a 24-year-old female was admitted with complaints of right upper quadrant abdominal pain and indigestion. Abdominal ultrasonography and ERCP showed a fusiform dilation of the common bile duct. During the operation, a tiny polyp was discovered in the cyst. We performed a cyst excision and a Roux-en-Y hepaticojejunostomy. On microscopic examination, the polyp was diagnosed as a tubular adenoma.
