 Case 1 is 60's male with gastric cancer checked by healthy check. Magnifying endoscopy with NBI(ME-NBI)showed a small depressed lesion with demarcation line, 3mm in size, which had irregular vessels. White zone appearance was unclear. Case 2 is 70's male introduced in order to surveillance after EMR for gastric cancer. Gastroscopy showed a small reddish lesion, 2mm in size, in the posterior wall of the gastric body. ME-NBI showed an irregular microvessels and disappearance of white zone component with demarcation line. Case 3 is 50's male referred to our hospital for further workup of gastric cancer. Gastroscopy showed many number of redness in the greater curvature of proximal antrum. ME-NBI showed an irregular microvessels, irregularity and disappearance of white zone component with demarcation line. We diagnosed all cases as minute mucosal cancer consist of differentiated adenocarcinoma by ME-NBI findings. We treated three cases by ESD without previous biopsy and could curative resection histologically.
