A Case of a Gastric Glomus Tumor with a Positive Cushion Sign / 대한소화기내시경학회지

ABSTRACT

Glomus tumors are commonly observed in the dermis or subcutis but are only rarely found in the stomach. A 52-year-old woman presented with an incidental finding of a submucosal tumor that showed a positive cushion sign in the stomach. Endoscopic ultrasonography (EUS) showed a 1.8x1.0 cm sized well-circumscribed homogenous hypoechoic tumor with side halos in the fourth sonographic layer of the gastric wall. Contrast enhanced abdominal computerized tomography (CT) demonstrated high enhancement of the tumor with the same level of enhancement as the portal vein for the arterial phase, with persistence of enhancement in the portal phase. For treatment, laparascopic wedge resection was performed. Histological findings of a biopsy specimen were compatible with a glomus tumor. Although it is difficult to diagnose a glomus tumor preoperatively, these characteristic findings determined with the use of EUS and CT seem to be useful to distinguish a glomus tumor from other tumors that arise from the third or fourth sonographic layer of the gastric wall.
