 Upper gastrointestinal endoscopy performed on a man in his 50s revealed a reddish flat lesion, 10mm in diameter, on the posterior wall of the lower gastric body. A biopsy was performed on the lesion, and the man was diagnosed with adenocarcinoma. Using ME-NBI(magnifying endoscopy with narrow band imaging), LBC(light-blue crest)was detected in the tumor but not in the surrounding mucosa. LBC was used as a demarcation line between the tumor and the surrounding mucosa. ME-NBI also revealed slightly irregular microvascular architecture and microsurface structure. These endoscopic findings suggested that the tumor was a type of low-grade, well-differentiated adenocarcinoma of the small intestinal ("crawling-type" adenocarcinoma). The surgeon performed an endoscopic submucosal dissection for histological assessment, and the results confirmed the findings of ME-NBI. We believe that ME-NBI used in this case was able to aid clear visualization of the features of this type of adenocarcinoma.
