We herein report a case of early gastric cancer with mixed components having different grades of atypia, which was correctly predicted by magnifying endoscopy combined with narrow band imaging. A 67‐year‐old man had a flat elevated lesion (0‐IIa) in the anterior wall of the gastric antrum. With narrow band imaging, a flat lateral extension (0‐IIb), not recognized with white light imaging was seen in the anal side of the main tumor. Magnifying endoscopy combined with narrow band imaging saw a relatively regular fine network pattern of micro‐vessels in the surface of the 0‐IIa area. However, in the surface of the 0‐IIb area, a villous structure with villi of various size and heterogeneity, micro‐vessels showing tortuousity were observed. We judged the grade of atypia to be higher in the 0‐IIb area than in the 0‐IIa area. Histological examination of the resected specimen verified the 0‐IIa area and 0‐IIb area as adenoma and adenocarcinoma, respectively.
