Histopathologic classification of CD based on Marsh-Oberhuber [
56,
57], and Corazza and Villanacci [
58] new grading system [
12,
57,
59].
| Marsh-Oberhuber classification | |
| (i) Marsh I: infiltrative lesion, normal villous architecture and mucosa, and IEL increase (>30–40 lymphocytes/enterocytes counted). | | (ii) Marsh II: hyperplasic lesion; similar to Marsh I with crypt hyperplasia. | | (iii) Marsh III: destructive lesion, subdivided to the following: | | (a) partial villous atrophy, | | (b) subtotal villous atrophy, | | (c) total villous atrophy. | |
| New grading system | |
| (i) Grade A (nonatrophic): >25 IELs/100 enterocytes. | | (ii) Grade B (atrophic): villous-crypt ratio <3 : 1. | | (iii) Grade B2 (atrophic): no detectable villi. | |
