Early gastric cancer presenting as a typical submucosal tumor cured by endoscopic submucosal dissection: A case report

Figure 1 Endoscopy images. A: Initial endoscopic image showing a 15 mm-sized submucosal tumor-like elevated lesion with normally appearing mucosa at the great curvature side of the proximal part of gastric antrum; B: Endoscopic image obtained 3 years later showing the tumor had not changed in size but that marked erythema had developed on overlying mucosa; C: Endoscopic image (c2 shows a higher magnification image of the mass) obtained 4 years after initial examination [immediately before endoscopic submucosal dissection (ESD)] showing the tumor had increased in size to 18 mm and developed a 5-mm-sized central ulcer and overlying reddish mucosa of fine granularity; D: Endoscopic image obtained approximately 2.5 years after ESD showing post-ESD scarring.
