On the occasion of a screening examination of the esophago-stomach, a slight elevated lesion in the Barett's mucosa was detected at the squamo-columnar junction of a 69-year-old man. Biopsy specimens revealed well differentiated adenocarcinoma. EMR (Endoscopic Mucosal Resection) was performed.
The resected specimens revealed that its invasion was within mucosa and cut ends were negative for carcinoma.
