Figure 1 Endoscopic manifestations of gastric and esophageal lesions. A: White-light endoscopy revealed a Borrmann type II lesion on the greater curvature of the lower stomach body, featuring an ulcer on the surface covered by a moss-like debris; B: Magnifying endoscopy with narrow-band imaging revealed a positive demarcation line, loss of mucosal structure, and an irregular microvascular pattern; C and D: Under white-light and narrow-band imaging, verrucous white patches with clear boundaries are visible; the biopsy specimen from these patches was soft.
