Gastric heterotopia of the duodenum is a relatively common finding of the duodenum.
General
- Common ~15% of cases in one series.[1]
- Probably not related to Helicobacter pylori.[2]
Can be subdivided into:[3]
- Foveolar epithelium with gastric pits
- Foveolar epithelium only.
Gross
- Typically nodules/polyps.[4]
Microscopic
Features:
- Foveolar epithelium.
- Gastric glands - body-type or antral-type.
DDx:
- Foveolar metaplasia (isolated) - see chronic duodenitis.
- Foveolar gastric-type dysplasia.[5]
