Metastasis of renal cell carcinoma (RCC) to the head and neck region is infrequent. A rare case of metastatic RCC, presenting as an enlarging neck mass and radiologically mimicking a carotid body tumour clinically and radiographically, presented in a 68-year-old male patient, 18 months after radical nephrectomy for RCC. It is estimated that 14-16% of all patients with renal cell carcinomas have metastases above the clavicle. However, there are no reported cases of metastatic renal cell carcinoma to the neck mimicking a carotid body tumour.
Renal cell carcinoma is the third most common neoplasm to metastasize to the head and neck region following breast and lung carcinomas.
肾细胞癌（RCC）转移至头颈部区域较为罕见。一名68岁男性患者，在接受RCC根治性肾切除术后18个月，出现了一例罕见的转移性RCC，表现为颈部肿块增大，临床和影像学上在放射学上酷似颈动脉体瘤。据估计，所有肾细胞癌患者中有14 - 16%发生锁骨以上转移。然而，尚无转移性肾细胞癌酷似颈动脉体瘤转移至颈部的报道病例。
肾细胞癌是继乳腺癌和肺癌之后转移至头颈部区域的第三大常见肿瘤。
