A 62‐year‐old woman was referred to Mie University Hospital, Tsu, Japan, for examination of upper gastrointestinal tract. The conventional endoscopy showed a slightly depressed lesion on the greater curvature at the gastric body. The surface of surrounding non‐neoplastic mucosa using magnification endoscopy with acetic acid was gyrus‐villous pattern whereas the surface of the lesion was rough. Furthermore, magnification endoscopy using acetic acid and narrow‐band imaging system visualized clearer fine surface pattern of carcinoma. The lesion had a rough mucosa with irregularly arranged small pits. The lesion was resected completely by endoscopic mucosal resection with insulated‐tip electrosurgical knife. Narrow‐band imaging system with acetic acid may be able to visualize not only the capillary pattern but also the fine surface pattern of gastric carcinoma.
