Figure 1 Endoscopic findings. A: A laterally spreading tumor-like elevated lesion was observed on white light endoscopy in the rectum; B: Narrow band imaging showed enlarged branch-like vessels on the surface of the lesion; C and D: Indigo carmine staining made the lesion margin clearer (C), and pit pattern II was observed on magnifying endoscopy (D); E: On assessment of the endoscopic submucosal dissection specimen, a slightly elevated, laterally spreading tumor measuring 25 mm × 20 mm was identified in the mucosal layer.
