Renal cell carcinoma (RCC) commonly metastasizes to the lung, liver, bones, and brain; however, cutaneous metastases remain rare with few reported cases. Since RCCs have the propensity to metastasize to highly vascular areas, the scalp and skin of the head and neck region are likely locations for cutaneous metastases. We report a rare case of a large, exophytic, cauliflower-like, hemorrhagic, metastatic mass of the posterior neck. This is the first reported case of a head and neck cutaneous RCC metastasis treated with endovascular embolization prior to surgical resection. Due to the increased vascularity of RCCs and risk of excessive hemorrhage during resection, adjunctive embolization of cutaneous head and neck metastasis may have a role. Essential characteristics to our treatment strategy are discussed with a review of pertinent literature.
肾细胞癌（RCC）通常会转移至肺、肝、骨和脑；然而，皮肤转移仍然罕见，报道的病例很少。由于肾细胞癌倾向于转移至血管丰富的区域，头皮以及头颈部皮肤很可能是皮肤转移的部位。我们报告了一例罕见的病例，患者后颈部有一个巨大的、外生性的、菜花状的、出血性的转移性肿块。这是首例报道的在手术切除前接受血管内栓塞治疗的头颈部皮肤肾细胞癌转移病例。由于肾细胞癌血管丰富且切除过程中存在过度出血的风险，对头颈部皮肤转移瘤进行辅助栓塞可能会起到一定作用。我们结合相关文献综述讨论了我们治疗策略的基本特征。
