[Malignant pyloric stenosis caused by cancer in para-pyloric ectopic pancreas].

Gastrointestinal symptoms with epigastric pain, nausea and loss in weight occasionally occur in patients with ectopic pancreas. Although ectopic pancreas is often found in the stomach, carcinoma in this ectopy is rare. This paper reports a case of pancreatic carcinoma arising in ectopic pancreas located in the gastric wall and causing pyloric obstruction. Malignant pyloric obstruction was the only radiographic sign. Microscopic examination led to the final diagnosis.
