Renal cell carcinoma (RCC) metastasis can involve any organ. Head metastasis are rare, namely tongue, scalp and nose and only a few cases have been described. The authors describe three cases of unusual presentation of head metastasis of RCC. In case 1, a 50-year-old man with RCC underwent left nephrectomy, and presented 16 months later with nasal metastasis. In case 2, a 64-year-old woman with RCC operated 12 years ago, relapsed at multiple sites including scalp, which was treated surgically. In case 3, a 47-year-old man with RCC developed metastasis in multiple organs including a mass on the tongue that was operated and was compatible with primary tumour metastasis. These cases show the importance of correct diagnosis of rare presentations and local treatment of metastasis of RCC.
肾细胞癌（RCC）转移可累及任何器官。头部转移罕见，如转移至舌、头皮和鼻，仅有少数病例报道。作者描述了3例RCC头部转移的特殊表现病例。病例1，一名50岁RCC男性患者接受了左肾切除术，16个月后出现鼻转移。病例2，一名64岁女性12年前接受了RCC手术，复发于包括头皮在内的多个部位，接受了手术治疗。病例3，一名47岁RCC男性患者出现多器官转移，包括舌部肿物，该肿物接受了手术治疗，符合原发性肿瘤转移。这些病例表明正确诊断罕见表现及对RCC转移进行局部治疗的重要性。
