Paneth cell metaplasia. H&E stain.
The Paneth cell is characteristic of the small intestine. It is also normal in the cecum, ascending colon and transverse colon.
Paneth cell metaplasia redirect to this article.
General
- Paneth cells should not be in the left colon[1] - if you see 'em think of inflammatory bowel disease and other long-standing injurious processes.
- Some claim that (friendly right colonic) paneth cells and paneth cell metaplasia look quite different and can be distinguished.[2]
Microscopic
Features:
- Supranuclear eosinophilic granules.
DDx:
- Enterochromaffin cells (AKA Kulchitsky cells).
- Subnuclear eosinophilic granules.
- Intraepithelial eosinophils.
- Eosinophils have smaller (~1/2) more intensely red granules.
