Abstract

Glomus tumors originate in modified vascular smooth muscle cells and are most commonly found in the dermis or subcutis but are rarely observed in the stomach. We report three cases of patients who presented with incidental findings of subepithelial tumors in the stomach. One patient showed a positive cushion sign, and the others showed negative cushion signs. Endoscopic ultrasonography (EUS) demonstrated sharply demarcated hypoechoic tumors with internal hyperechoic spots in the fourth layer of the gastric wall and several hypoechoic halos around the tumors. Contrast-enhanced abdominal computerized tomography (CT) showed homogeneous high enhancement of tumors up to the delayed scan, and one case showed calcification in the tumor. For treatment, laparoscopic wedge resections were performed. Histological and immunochemical analysis of the tumor cells were compatible with glomus tumors. These characteristic findings in EUS and CT seem to be useful for the diagnosis of gastric glomus tumors.
