A 79-year-old male was diagnosed with Long segment Barrett’s esophagus in 2011. Three metachronous superficial Barrett’s esophageal adenocarcinomas (s-BEAs) were detected two years later. Two of the 3 cancers were detected by magnifying endoscopy with narrow band imaging (ME-NBI) . Endoscopic submucosal dissection was performed on all 3 lesions and the pathological findings were intramucosal cancers. In our case, ME-NBI was very useful for detecting s-BAE. s-BEA on ME-NBI was observed as a brownish area.
