위에 발생한 사구종양 1 예 : 내시경 초음파검사 소견을 중심으로

A glomus tumor of the stomach is a rare submucosal lesion that was first described by De Busscher in 1948. Submucosal tumors of the stomach are mostly leiomyoma, leiomyosarcoma, and malignant lymphoma. It is difficult to diagnose this kind of tumor preoperatively, We present a patient with a gastric glomus tumor which showed the characteristic endoscopic ultrasonographic (EUS) finding. Our case was also diagnosed by pathology after surgery. The major EUS findings in the present case are circumscribed low echoic mass in the forth submucosal layer and an internal heterogenous echo mixed with high echoic spots. The EUS seems to be useful in distinguishing between glomus tumor and other submucosal tumors.
