Figure 2 Coincidence of florid intestinal endometriosis and Crohn’s disease in small intestinal wall. A: Complex inflammatory mucosal injury with establishment of pyloric gland metaplasia (asterisk). In deeper layers severe lymphoid aggregates (arrows) accompanied by endometrial glands exist (HE, × 10); B: Strong lymphoid hyperplasia partially affecting the prominent neuronal plexus, and serositis (HE, × 10); C: Florid aphthous mucosal lesion (HE, × 10), the arrows indicate endometriosis. D: Higher magnification of intestinal endometriosis(HE, × 100). Examples of epithelial proliferates are marked by an arrow. The cytogenic stroma is highlighted by asterisks. Note the intraglandular aggregates of erythrocytes.
