横紋筋肉腫様細胞を伴った腎細胞癌の1例

Abstract

In Feb 2009, a-54-year-old female complained of left flankpain and macrohematuria. Computed tomography (CT) demonstrated the left renal tumor. In Mar 2009, she was referred to our hospital. On physical examination a hard mass was found in her left abdomen. CT demonstrated the left renal tumor and tumor thrombus of left renal vein, but we did not detect any remarkable metastasis in other organs. Thus, we performed left radical nephrectomy. The pathologic finding was renal cell carcinoma (RCC) with rhabdoid features and sarcomatoid change. Eight months postoperatively, she is alive without evidence of recurrence and metastasis. RCC with rhabdoid features and sarcomatoid change is rare. We discuss this case, and review the literature.
