Large colonic lipoma with a laterally spreading tumor treated by endoscopic submucosal dissection: A case report

Figure 1 Colonoscopic images. A: Colonic lipoma with a laterally spreading tumor (LST) of granular type. The margin of the LST was observed along the yellow arrow. It was difficult to observe the overall margin of the LST because the LST was pressed against the lipoma; B: When the patient’s posture was changed to the supine position, LST invasion was not observed in the neck of the lipoma.
