(a) Photomicrograph of the small intestinal mucosa and submucosa. The lamina propria and submucosa are expanded by chronic nonsuppurative inflammation with vascular congestion, acute erosive necrotizing enteritis, and bacterial colonization of necrotic surface debris. Hematoxylin and eosin, ×100 magnification. (b) Photomicrograph of the small intestinal submucosa. Periarterial nonsuppurative inflammation is visible, with acute changes including lymphatic dilation, edema, and segmental leukocytoclastic necrotizing arteritis. Hematoxylin and eosin, ×100 magnification.
