Figure 8
From: A contemporary and critical appraisal of ‘indeterminate colitis’

Medium-power image of a patient with diverticular disease-associated colitis showing involvement of the mucosa (only in the area of diverticular disease), and diverticular out-pouches as well. In this image, there is diffuse lymphoplasmacytosis of the lamina propria, loose granulomatous inflammation related to a ruptured crypt, basal plasmacytosis, and foreshortening and slight distortion of the crypts, similar to UC.
