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
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].
