 Ulcer healing process after endoscopic mucosal resection (EMR) for esophagus was studied through 50 lesions of 32 cases treated in our department. Ulceration after EMR was cured, but left a scar covered with regenerated epithelium in one month. Regenerated epithelium grew gradually and the papilla-pattern of regularly arranged white spots observed in normal mucosa appeared on the surface. Magnified or close observation was useful to distinguish from local recurrence iodine undyed areas which appeared around scar formation. All of three recurrent cases were detected as a reddening erosion. In two of those cases the recurrent sites were the anal side of the primary lesion where observation was not sufficient because of the outer pressure from neighboring organs. Multiple cases, simultaneous or heterochronous, usually have background mucosa with diffusely scattered iodine undyed lesions. Magnifying endoscopy is also useful to pick up lesions from such multiple undyed spots.
