ME-NBI findings of early gastric cancer. (a) A depressed lesion showed absent surface pattern, a fine network of abnormal microvessels, and a clear demarcation line. Histology revealed high-grade adenoma with severe dysplasia (category 4.1 in the Vienna classification). (b) A well-differentiated adenocarcinoma demonstrated destructed surface pattern and dense irregular microvascular architecture: dilatation, torturous running, caliber changes, and communication of microvessels. (c) An undifferentiated adenocarcinoma showed that surface structure was almost disappeared and corkscrew-like or branched thick microvessels were sparsely distributed.
