A; Signet ring cell carcinoma of 3.0 cm in diameter, showing depressed early gastric cancer in the lesser curvature of the lower stomach.
B; Well differentiated tubular adenocarcinoma of 1.3 cm in diameter, showing raised type early gastric cancer in the lesser curvature of the middle stomach.
C; Moderately differentiated tubular adenocarcinoma of 1.0 cm in diameter, showing depressed type early gastric cancer with accompanying erythema in the lesser curvature of the lower stomach.
D; A scar with accompanying erythema observed after endoscopic mucosal resection （EMR） of early gastric cancer in the curvatura ventriculi major of the middle stomach. No malignancy was revealed in this case.
