| Abstract: | Abstract: A rare case of gastric lipoma removed by endoscopic polypectomy is presented herein. A 64-year-old female was found to have a polypoid lesion in the stomach on periodic X-ray examination. Endoscopy revealed a submucosal tumor located on the posterior wall of the antrum. Endoscopic ultrasonography demonstrated a homogeneous, hyperechoic mass continuous with the submucosal layer, suggesting a lipoma. Because the likelihood of the tumor ultimately causing obstruction or prolapse into the duodenum was high, endoscopic polypectomy was performed. There were no complications. The histological examination revealed a mass of mature adipose tissue underneath the normal mucosa, which was consistent with the diagnosis made prior to polypectomy. The preferred treatment for gastric lipomas to date has been surgical excision, because the diagnosis is difficult to make prior to treatment. In the literature, only 17 cases undergoing endoscopic treatment for gastric lipomas have been reported. Endoscopic ultrasonography and computed tomography apparently facilitate preoperative diagnosis of lipomas. |
