4 Figure 3 (A) Endoscopic image of distal gastric corpus and antrum showing a large ulceration extending from the antrum on the posterior gastric wall with surrounding pale mucosa. (B) Endoscopic image of the gastric angularis showing a large ulceration extending from the antrum to the fundus on the posterior gastric wall with surrounding pale mucosa. (C) Histopathologic image demonstrating features of acute gastric ischemia: mucosal necrosis, hemorrhage, with abundant inflammation and microabscess formation (arrowheads; H&E; original magnification, ×20). (D) On follow-up endoscopy a week later, the distal gastric corpus and antrum show a healing large posterior ulceration extending from the antrum with surrounding pink mucosa. (E) On follow-up endoscopy a week later, the gastric angularis shows a healing large posterior wall ulceration with surrounding pink mucosa. (F) Histopathologic image showing resolution of the microabscesses, acute ulceration, and hemorrhage (H&E; original magnification, ×20).
