 A female patient in her 70's who received Helicobacter pylori eradication therapy 13 years ago was referred to our hospital for further examination. Conventional endoscopic findings showed a discolored, slightly protruding lesion measuring approximately 3 mm that was located at the anterior wall of the middle gastric corpus. Magnifying endoscopy with narrow-band imaging showed minute granular structures with a demarcation line. An early stage gastric cancer was suspected because of the irregular microsurface and microvessel pattern. Histopathologic findings of the resected specimens by ESD treatment revealed a well-differentiated, MUC5AC-positive adenocarcinoma. Furthermore, normal fundic glands were seen beneath the carcinoma. The final pathological stage was pStage I[3×3 mm, tub1, pT1a, ly(−), v(−), HM0, VM0]. This case was diagnosed as minute early gastric cancer with foveolar epithelium differentiation, after eradication therapy.
