Papillary adenoma of the distal common bile duct associated with a synchronous carcinoma of the peri-ampullary duodenum.
BACKGROUND
Benign tumours of the biliary tract are an extremely rare group of neoplasms. The diagnosis of these rare tumours is established on histopathological analysis following resection. Coincidence of a biliary adenoma of the distal common bile duct and a synchronous adenocarcinoma of the peri-ampullary duodenum has never been reported in the literature.


METHODS
We report a case of a papillary adenoma in the common bile duct in a 75-year-old female, who had synchronous invasive adenocarcinoma of the peri-ampullary duodenum.


CONCLUSIONS
Isolated papillary adenoma of the bile duct is extremely rare, and in this unusual case it coincided with a peri-ampullary duodenal adenocarcinoma. However, this is a rare instance of an incidental finding within the distal bile duct following pancreaticoduodenectomy for curative treatment of a peri-ampullary adenocarcinoma.
