A 37-year-old woman was found to have a submucosal mass in the gastric antrum. She presented with recurrent episodes of right upper quadrant pain. Evaluation included a normal abdominal ultrasonography and esophagogastroduodenoscopy, which revealed a benign appearing 1 cm sessile polypoid mass in the gastric antrum (Image 1). The gastric mucosa over the mass was normal both visually and histopathologically on biopsies. Endoscopic ultrasonography revealed a 1x0.5 cm submucosal mass (Image 2). The patient strongly desired having this removed and, therefore, was operated with the presumed diagnosis of a gastric leiomyoma. The mass, easily identified at surgery, was removed through a gastrotomy. Histology revealed ectopic pancreatic tissue within the gastric submucosa.
While this is not an uncommon finding on the serosa of the small bowel (Image 3), a submucosal pancreatic rest is quite unusual [1, 2, 3].
