Heterotopic Pancreas : Gross

Comments:
At endoscopy, heterotopic pancreas in stomach appears as a dome-shaped, intramural nodule with smooth overlying mucosa. A central umbilication or dimple marks the site of draining duct.

Grossly, it is a well-circumscribed, yellowish, lobulated nodule resembling normal pancreas, located in the submucosa (73%), muscularis propria (17%) or subserosa (10%). This image shows gastric heterotopic pancreas. See previous image for intact gross specimen.
