title: Myxoma of the superior vena cava origin presented as a right atrial mass.
abstract: Myxomas are the most common benign cardiac tumors. Myxomas are more common in the left heart chamber than the right side chamber. An extracardiac origin presenting as a right atrial mass is very rare. We present a case of myxoma originating in the superior vena cava (SVC) in a 24-year-old man, who underwent surgical resection. Preoperative two-dimensional echocardiography demonstrated a mass in the right atrium. Intraoperatively, the tumor was found to have originated from the SVC orifice. The tumor was excised from the SVC by opening the one-third proximal portion of the SVC. Pathological examination revealed a myxoma, and one-year follow-up showed no evidence of the recurrence of any tumors in the SVC.
