　A 60-year-old woman complained of heartburn. Endoscopy revealed a tumor in the esophagus, and she was referred to our hospital. The tumor was a flat elevated lesion in a long-segment Barrett's esophagus located 26～29cm from the mouth along the total esophageal length. The center of the lesion had a reddish excavation, and an extended hypovascular area was observed around the lesion. The histological findings of a biopsy were consistent with Barrett's esophageal adenocarcinoma. We determined that the tumor invasion depth was within DMM, and performed ESD after obtaining informed consent. The histological findings of the resected specimen were consistent with well to poorly differentiated adenocarcinoma restricted to the mucosa. The tumor invasion depth was confirmed to be within DMM, and lymphatic vessel invasion was also recognized. The patient was treated with chemotherapy and followed up in our hospital.
