'''Eosinophilic colitis''', abbreviated '''EC''', is an inflammatory process involving the [[colon]] ([[colitis]]) characterized by abundant [[eosinophil]]s. | |||

- 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. | |||

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. | |||
