A 37-year-old woman was referred to our hospital for fecal blood. Colonoscopic examination revealed a laterally spreading tumor, 15mm in diameter, at the rectum. Prior to the endoscopic polypectomy, submucosal injection of hypertonic saline-epinephrine was performed. However, because it was judged that the total specimen was unable to be excised by EMR at one time, we decided to try the transanal resection. But we failed it, and colonoscopy was performed again for the purpose of piecemeal EMR 11 days after submucosal injection. The lesion was ulcerlized and no adenoma component was recognized histopathologically. We report this rare case, that the disappearing process was endoscopically able to be observed after submucosal injection to a flat colonic lesion.
