Figure 1

(a) Gross appearance of the gastric ulcer. In the gastric angulus, a 1.7 cm × 0.6 cm healing ulcer was observed. The arrow indicates the gastric ulcer. (b) Hematoxylin and eosin- (H&E-) stained figure of the gastric ulcer (×100). (c) H&E-stained figure of the granulation tissue of the healing stage of the gastric ulcer (×200). Eosinophilic infiltration is observed around capillaries without vasculitis. (d) Higher magnification (×400) of subfigure (c). H&E-stained figure of the submucosal layers of the stomach (×200) (e) and small intestine (×200) (f). Eosinophilic infiltration is observed without vasculitis. M: mucosal layer. Scale bars = 100 μm (b), 50 μm (c, e, and f), and 20 μm (d).
