Renal cell carcinoma (RCC) is the most frequent cancer of the kidney and it accounts for 3% of all solid malignancies. Although rare, cutaneous metastases can be an important manifestation of RCC. We present a case of a 56-year-old male with a history of RCC, followed by the development of cutaneous metastases 4 years later with an uncommon clinical presentation. RCC is the most common genitourinary cancer to metastasize to the skin and accounts for 6.8% of cutaneous metastases. These patients have a poor prognosis. It is essential for these patients to perform a complete periodic dermatologic examination for proper restaging and treatment.

肾细胞癌（RCC）是最常见的肾脏癌症，占所有实体恶性肿瘤的3%。虽然罕见，但皮肤转移可能是RCC的重要表现。我们报告一例56岁男性，有RCC病史，4年后出现皮肤转移，临床表现不常见。RCC是最常见转移至皮肤的泌尿生殖系统癌症，占皮肤转移的6.8%。这些患者预后较差。对这些患者进行完整的定期皮肤科检查以进行适当的再分期和治疗至关重要。
