A 73-year-old woman was referred to our hospital with an enlarging gastric submucosal tumor (SMT) in the gastric body on the lesser curvature side with the diagnosis of lipoma. Follow-up esophagogastroduodenoscopy detected a well differentiated adenocarcinoma of 0-Ⅱc type in the mucosa just above the lipoma, which had increased in size. For the simultaneous treatment of early gastric cancer and lipoma, we devised the endoscopic unroofing method using circumferential incision. The endoscopic unroofing method using circumferential incision was useful in the treatment of early gastric cancer and reduction of the lipoma. This endoscopic procedure resulted in relatively easy curative resection of the mucosal cancer just above the lipoma. We report its details along with a review of the related literature.
