Abstract: Renal collecting duct carcinoma(CDC) is rare in clinic, complicated with clear cell renal cell carcinoma(ccRCC) of one kidney is extremely rare. We reported a case CDC complicated with ccRCC of one kidney. The patient was admitted as left low back pain and gross hematuria, preoperative CT examination showed that one tumor was found in the upper middle pole and another tumor at lower pole of the left kidney, and multiple enlarged lymph nodes in the medial edge of the kidney. CT diagnosis was renal collecting duct carcinoma complicated with clear cell carcinoma of the left kidney, retroperitoneal lymphatic metastasis and underwent radical nephrectomy. Postoperative pathological diagnosis was CDC(upper middle pole) complicated with ccRCC(lower pole)of the left kidney. The patients were treated with sunitinib for 6 months and survived 13 months, and died of extensive metastasis.
