Hyperplastic polyp of the stomach, also gastric hyperplastic polyp, is a common pathology of the stomach. Hyperplastic polyps more generally are dealt with in the hyperplastic polyp article.
General
- Benign.
- Most common gastric polyp.[1]
Gross
- Polypoid mass.
Microscopic
Features:[2]
- Abundant foveolar cells and elongated glands - key feature.
- +/-Gland dilation.
Negatives:
- No atypical nuclei.
- No hyperchromasia.
- No loss of pseudostratification.
Notes:
- No serrations - as in the colon.
DDx:
- Ménétrier's disease[3] (hyperplastic hypersecretory gastropathy).
- Juvenile polyp[1] - abundant lamina propria, dilated glands may have neutrophils.[4]
- Peutz-Jeghers polyp - thick superficial muscle.
- Fundic gland polyp - doesn't have foveolar hyperplasia.

Micro
The sections show antral-type gastric mucosa with hyperplastic gastric pits. No gland dilation is apparent. The epithelium matures to the surface. The lamina propria is not expanded.
Focal neutrophilic inflammation is present. No Helicobacter-like organisms are identified. No intestinal metaplasia is present. No mitotic activity or nuclear atypia is apparent.
