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.
