Ectopic pancreatic tissue in the gallbladder; Report of a case and review of literature

Abstract

Ectopic pancretic tissue is often found in the gastrointestinal tract but rarely in the gallbladder. In a 31-year-old female complaining of right upper quadrant pain, ultrasonography demonstrated gallbladder stone. Cholecystectomy was performed and microscopic examination of the resected specimen revealed pancreatic acini and duct measuring 1mm in the cystic duct. Islet of Langerhans was not present. Thirty-two reported cases have been reviewed. Incidence of ectopic pancreas in the gallbladder is only 1.5%.
