A typical case of EGC diagnosed after successful H. pylori eradication treatment. EGD indicated a depressed (0-IIc), reddish lesion in the lesser curvature of the gastric corpus (a). Diagnosis of neoplastic or nonneoplastic lesion was difficult by the targeted biopsy during the pretreatment EGD. Histological assessment of resected specimen showed nonneoplastic epithelium covering the cancerous tissue, (b) and (c). (b) TP53 immunohistochemistry; (c) hematoxylin and eosin stain.
