摘要
The gallbladder is an unusual location of pancreatic heterotopia defined as the presence of pancreatic tissue lacking anatomical and vascular continuity with the main body of the gland. A 55-year-old previously healthy male patient presented with repeated attacks of right hypochondriac pain and vomiting. On physical examination, the right upper abdomen was tender to palpation with a positive Murphy's sign. Abdominal ultrasonographic examination showed multiple gallstones within a thin-walled gallbladder. Laparoscopic cholecystectomy was performed with uneventful recovery. Macroscopic examination of the surgical specimen revealed a yellowish intramural nodule measuring 7 mm close to the neck of the gallbladder. Histological examination revealed chronic cholecystitis and subserosal foci of heterotopic pancreas made up of exocrine acinar and ductal elements without islet cells corresponding to incomplete heterotopia. Heterotopic pancreas is usually detected as an incidental microscopic finding in a gallbladder specimen removed by cholecystectomy. Pre-operative diagnosis is difficult primarily due to its non-specific clinical features.
