Renal cell carcinoma (RCC) usually presents clinically in the advanced stage including bone metastasis. However metastatic RCC without evidence of a primary tumor in the kidney is extremely rare. We herein report a case of a 70-year-old male initially evaluated for bone lesion and diagnosed with biopsy-proven metastatic clear cell RCC without a renal primary. Given the rare nature of the disease, there is no standardized course of treatment that has yet been established. We believe that our case will add to the body of knowledge about uncommon oncologic instances and consolidate the information that has already been published.
肾细胞癌（RCC）通常在晚期临床出现，包括骨转移。然而，没有肾脏原发性肿瘤证据的转移性RCC极为罕见。我们在此报告一例70岁男性病例，该患者最初因骨病变接受评估，经活检证实为无肾原发性的转移性透明细胞RCC。鉴于该疾病的罕见性，尚未建立标准化的治疗方案。我们相信，我们的病例将增加有关罕见肿瘤病例的知识体系，并巩固已发表的信息。
