Abstract

Glomus tumors originate in modified vascular smooth muscle cells and are most commonly found in the dermis or subcutis butare rarely observed in the stomach. We report three cases of patients who presented with incidental findings of subepithelial tumorsin the stomach. One patient showed a positive cushion sign, and the others showed negative cushion signs. Endoscopicultrasonography (EUS) demonstrated sharply demarcated hypoechoic tumors with internal hyperechoic spots in the fourth layer ofthe 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. Fortreatment, laparoscopic wedge resections were performed. Histological and immunochemical analysis of the tumor cells werecompatible with glomus tumors. These characteristic findings in EUS and CT seem to be useful for the diagnosis of gastric glomustumors.

사구 종양은 사구체(glomus body)의 변형된 평활근 세포에서 유래하는 양성종양으로 일반적으로 사지 말단에서 발생하나, 위장관의 사구종양은 매우 드문 것으로 알려져 있다. 저자들은 건강 검진 시 우연히 발견된 위 상피하종양을 주소로 내원한 환자에서 내시경 초음파 검사 및 CT 검사 후 수술을 통해 조직학적으로 사구종양으로 확인된 세 증례를 경험하였다. 세 증례 모두 내시경 초음파에서 제 4층에서 국소적 고에코를 보이는 비균질성 저에코 병변이 관찰되었고, CT에서 강한 조영 증강 및 이러한 조영 증강이 지연기까지 지속되는 과혈관 종양의 특징적인 소견을 보였다. 이중 한 증례는 특징적으로 쿠션 양성 소견과 CT에서 석회화 소견을 보였다. 저자들은 세 증례에서 사구종양의 서로 다른 특성을 경험하였기에 보고하는 바이다.
