[Heterotopic pancreas in gallbladder].

UNLABELLED: Heterotopic pancreas in the gallbladder is uncommon.condition and its clinical presentation is as an intramural nodule near the cystic duct, with an incidental finding in most cases.

OBJECTIVE

to update Heterotopic pancreas condition in the gallbladder. We reported a case of a 18-year-old female, suffering with biliar colic who was operated on with diagnosis of acute cholecystitis. Six mixed gallstones were found in the surgery and the gallbladder was distended and edematous with serosal exudate and the serosa appeared discolored and hemorrhagic. The wall was thickened with edema and hemorrhage. Microscopic findings were: congestive mucosa , edema, acute inflammatory cells and fibrin deposition on the wall and a subtle (myo)-fibroblastic proliferation. The nodule was diagnosed as macroscopic heterotopic pancreatic tissue in the gallbladder wall thickness, without neoplastic changes. Clinical presentation as acute cholecystitis has been rarely reported in the presence of heterotopic pancreatic tissue.
