Metastasis of renal cell carcinoma (RCC) to the nasal cavity and paranasal sinuses is rare, with fewer than 50 cases described in the literature. Nasal metastasis as the initial presentation of RCC is even rarer. Metastases to the nasal cavity usually represent advanced disease with poor outcome. The authors report a case of metastatic RCC presenting with right nasal cavity mass and epistaxis, followed by a brief review of the relevant literature.
肾细胞癌（RCC）转移至鼻腔和鼻窦罕见，文献报道不足50例。以鼻腔转移作为RCC的首发表现更为罕见。鼻腔转移通常提示疾病晚期，预后较差。作者报告1例以右侧鼻腔肿物和鼻出血为表现的转移性RCC病例，并对相关文献进行简要回顾。
