Ectopic Pancreatic Tissue Presenting as Gastric Tumor – A Case Report

Heterotopic pancreas is a pancreatic tissue located outside the usual anatomical location of the pancreas. Heterotopic pancreas was first described in 1727 by Schultz in the diverticulum of the ileum. A 61-year-old man was admitted to the Second Department of Surgery with the following complaints: heaviness and pain in the epigastrium and right subcostal area, accompanied by nausea, vomiting, lack of appetite and weight reduction about 20 kg over the last few months. Intraoperatively tumor formation was found located in the pyloro-antral gastric area with approximate size 4/5 cm in diameter. The histological examination of the specimen revealed an uncapsulated formation of pancreatic glandular serine acres and single Langerhans islets among cystic dilated and deformed pancreatic ducts without epithelial cellular atypia.
