초록
Cardiac metastasis from renal cell carcinoma (RCC) without inferior vena cava (IVC) involvements is extremely rare with few reportedcases. Sarcomatoid RCC with rhabdoid feature is a rare pathologic type of RCC having aggressive behavior due to greatmetastatic potential. Here, we report a case of rapidly growing cardiac metastasis of RCC which brought on right ventricular outflowtract (RVOT) obstruction without IVC and right atrial involvement in a 61-year-old woman. Cardiac arrest occurred duringradical nephrectomy and echocardiography revealed mass nearly obstructing the RVOT which was not recognized by preoperativeechocardiography 1 month ago. Postoperative immunohistochemical evaluation of renal mass revealed sarcomatoid RCCwith rhabdoid feature.
Abstract
Cardiac metastasis from renal cell carcinoma (RCC) without inferior vena cava (IVC) involvements is extremely rare with few reportedcases. Sarcomatoid RCC with rhabdoid feature is a rare pathologic type of RCC having aggressive behavior due to greatmetastatic potential. Here, we report a case of rapidly growing cardiac metastasis of RCC which brought on right ventricular outflowtract (RVOT) obstruction without IVC and right atrial involvement in a 61-year-old woman. Cardiac arrest occurred duringradical nephrectomy and echocardiography revealed mass nearly obstructing the RVOT which was not recognized by preoperativeechocardiography 1 month ago. Postoperative immunohistochemical evaluation of renal mass revealed sarcomatoid RCCwith rhabdoid feature.
