Deng Gao LIU, Xu Chen MA, Chuan Bin GUO, Fu Yun ZHAO, Hai Yan LUO
Renal cell carcinoma (RCC) is the third most frequent infraclavicular tumour to metastasise to the extracranial region of the head and neck. Metastasis occurs in about 15% of patients with RCC, but only 1% of the patients have metastasis confined to the head and neck. This paper reports three cases of RCC with metastases to the unilateral parotid, the bilateral parotid and the paranasal sinuses. The clinical behaviour and radiographic appearance are reviewed, and the treatment options are also discussed. Key words: renal cell carcinoma, metastasis, head and neck
