Intracardiac Glomus Tumor Obstructing the Right Ventricular Outflow Tract: A Rare Case Report.

Abstract

Intracardiac glomus tumors are very rare neoplasms arising from mesenchymal cells. Solitary glomus tumors are usually benign and mostly seen in the skin of limbs. Still, exceptional cases of noncutaneous visceral glomus tumors have been reported at sites other than the limbs. We present a case of glomangioma that was surgically removed from the right ventricle and briefly pointed to the importance of differential diagnosis of cardiac tumors. A 57-year-old woman was referred to our hospital for dyspnea and recurrent arrhythmia attacks. We performed a three-dimensional transthoracic echocardiogram, and contrast chest CT, which revealed a mass in the right ventricle. She was successfully treated with cardiac surgery. After pathological studies, the tumor was finally diagnosed as benign intracardiac glomangioma.
