Figure 2. The macroscopic appearance of the descending colon from the serosal side (A) and the mucosal side (B) showing a distinct line of demarcation between healthy and ischemic bowel segments. Microscopic examination of the resected colon revealed denuded and sloughed mucosal surface (H&E, ×10) (C). The medium-sized arteries in the mesocolon showed inflammatory changes in their walls with foci of necrosis suggestive of vasculitis (H&E, ×40) (D).

H&E: hematoxylin and eosin
