A CASE OF GASTRIC LIPOMA DIAGNOSED BY ENDOSCOPIC SUBMUCOSAL DISSECTION

Abstract

A 62-year-old woman was referred to our hospital with an enlarging gastric submucosal tumor (SMT). Her gastric SMT was considered to be a lipoma on the basis of findings in plain radiography, esophagogastroduodenoscopy, and endoscopic ultrasonography. However, we could not exclude the possibility of a malignant neoplasm because the lesion was increasing in size. Therefore, we performed endoscopic submucosal dissection (ESD) because the SMT was located in the submucosal layer. Local complete resection of the SMT was achieved, and we diagnosed the SMT as a benign lipoma. Our case suggests the clinical benefit of ESD for therapeutic diagnosis of gastric SMTs.
