Figure 3. Photomicrograph of the small-bowel mucosa and submucosa of a patient with Crohn's disease of the small bowel.
The mucosa contains moderate acute and chronic inflammation with reactive changes in the epithelial cells. A fissuring ulcer is evident centrally, extending into the muscularis mucosa. Pyloric metaplasia is noted focally (black arrow) (hemotoxylin and eosin,
