Figure 1 A, Colonoscopic image showing an irregular ulcer with surrounding edema and erosion in the rectum under white light. B, Magnetic resonance image showing localized wall thickening in the middle part of the rectum. C, D, Probe-based confocal laser endomicroscopic image showing (C) dark thickened epithelium and dilatated vessels and (D) villous architecture and decreased crypt/stroma ratio with reticular gray pattern in stroma. E, F, Histologic views of the biopsy specimen showing fibromuscular obliteration of the lamina propria, hyperplasia of epithelium, and dilatation of small vessels at (E) low power (H&E, orig. mag. ×1.78) and (F) high power (H&E, orig. mag. ×20).
