Ectopic pancreas mimicking submucosal gastric tumor

A 35-year-old man presented with intermittent epigas- tric pain for about 3 months. On physical examination, the patient was in good health ; bowel sounds were normal and there was no tenderness in the epigastric region; the liver and the spleen were not palpable. Laboratory findings were normal. An upper gastroin- testinal endoscopy revealed a submucosal lesion over- lying the mucosa of the posterior wall of the fundus. The submucosal lesion measured about 2 cm in diameter. The histopathological examination of the biopsy sample revealed chronic gastritis and mucosal hyperplasia. Biopsies collected endoscopically do not often provide the representative histological sample needed for further therapeutic decisions.
