6. Figure 5
Sections show cryptitis, crypt abscesses, basal lymphoplasmacytosis, and architectural distortion in this resection specimen from a patient with diverticular disease–related segmental colitis. Note that the inflammatory process is confined to the mucosa (hematoxylin-eosin; original magnification 200 ×).
