Under a provisional diagnosis of differentiated adenocarcinoma without local lymph node metastasis, endoscopic submucosal dissection (ESD) was carried out. En bloc resection with tumor-free lateral/basal margins was accomplished without complication. The resected area was 12 x 15 mm in size, whereas the neoplastic lesion was 4 x 4 mm. Histopathological examination confirmed intramucosal well-differentiated tubular adenocarcinoma without angiolymphatic invasion adjacent to the muscularis mucosae. Repeated esophagoscopy 6 months after ESD showed neither locally recurrent nor metachronous lesions. Considering that Barrett's esophagus is a precancerous condition, one may recommend eradication of both the neoplastic and non-neoplastic lesion with using ESD.
