Eosinophilic colitis, abbreviated EC, is an inflammatory process involving the colon (colitis) characterized by abundant eosinophils.
Eosinophilic proctitis redirects to this article, as the histology is quite similar.

- Granular appearance.
Microscopic
Features:[1]
- Abundant eosinophils - no agreed upon number.

DESCENDING COLON, BIOPSY: - COLONIC MUCOSA WITH MILD EOSINOPHILIA, SEE COMMENT. - NEGATIVE FOR DYSPLASIA. COMMENT: Focally, there are up to 40 eosinophils / 0.2376 mm*mm (approx. field area at 400X). This is a non-specific finding. No eosinophilic crypt abscesses are seen. No (neutrophilic) cryptitis is present. Clinical correlation is suggested.
DESCENDING COLON, BIOPSY: - COLONIC MUCOSA WITH MILD EOSINOPHILIA, SEE COMMENT. - NEGATIVE FOR ACTIVE COLITIS. - NEGATIVE FOR DYSPLASIA. COMMENT: There are up to 40 eosinophils / 0.2376 mm*mm (field area at 400X). This is a non-specific finding. The differential diagnosis includes inflammatory bowel disease, infection (especially helminths), a drug reaction, and autoimmune disorders (e.g. Churg-Strauss syndrome, celiac disease, scleroderma). Clinical correlation is required.
