title: Rapidly Growing Right Ventricular Outflow Tract Mass in Patient with Sarcomatoid Renal Cell Carcinoma.
abstract: Cardiac metastasis from renal cell carcinoma (RCC) without inferior vena cava (IVC) involvements is extremely rare with few reported cases. Sarcomatoid RCC with rhabdoid feature is a rare pathologic type of RCC having aggressive behavior due to great metastatic potential. Here, we report a case of rapidly growing cardiac metastasis of RCC which brought on right ventricular outflow tract (RVOT) obstruction without IVC and right atrial involvement in a 61-year-old woman. Cardiac arrest occurred during radical nephrectomy and echocardiography revealed mass nearly obstructing the RVOT which was not recognized by preoperative echocardiography 1 month ago. Postoperative immunohistochemical evaluation of renal mass revealed sarcomatoid RCC with rhabdoid feature.
