A case report of ectopic pancreatic tissue in the gallbladder.

Heterotropic pancreatic tissue is a rare entity where aberrant pancreatic tissue is located without any anatomical connection to the pancreas. It is usually reported to be found in stomach, duodenum, jejunum and spleen. Rare locations include lung, mediastinum, liver, mesentery, ileum, meckels diverticulum and gallbladder [1, 2]. This anomaly is often an incidental finding during laparotomy or autopsy. We describe a case of an elective laparoscopic cholecystectomy with the histology of the gallbladder showing focal ectopic pancreatic acinar tissue.
