The pathology of colonoscopy showed that there was chronic active enteritis with different degrees of eosinophils infiltration in transverse colon, sigmoid colon and rectum, and there was chronic enteritis in descending colon and ileocecal valve. Numerous eosinophils (about 80/HPF) populate the lamina propria (arrow) in the section of transverse colonic (Fig. 2a, HE× 200, HE× 400 in the circle) and rectal (Fig. 2b, HE× 200, HE× 400 in the circle) mucosa. And small amount of eosinophils (about 25/HPF) infiltrate in lamina propria (arrow) in the section of sigmoid (Fig. 2c, HE× 200, HE× 400 in the circle) mucosa. A few eosinophils (about 10/HPF) populate the lamina propria (arrow) in the section of descending colon mucosa (Fig. 2d, HE× 200, HE× 400 in the circle). Only several eosinophil infiltrate in the mucosa of ileocecal valve (Fig. 2e, HE× 200, HE× 400 in the circle)
