Adenocarcinoma arising from an ectopic pancreas in the stomach

Endoscopy. 2002 Dec;34(12):1014-7. doi: 10.1055/s-2002-35836.


Ectopic pancreas is rare, being found in between 0.6 % and 15 % at autopsy. Heterotopic pancreas is usually an asymptomatic condition which is found incidentally at surgery or at autopsy. Occasionally, significant symptoms arise from complications, such as recurrent upper gastrointestinal bleeding, biliary or intestinal obstruction, or malignant degeneration. Malignant change is very rare. We report a case of malignant change (adenocarcinoma) in an ectopic pancreas in the stomach. In the literature, there are eight reported cases of malignant change in ectopic gastric pancreas. The prognosis in the other reported cases is unknown, but in our patient, the tumor was confined to the muscle of the stomach and there was no lymph node invasion.
