Metastasis of renal cell carcinoma (RCC) to the head and neck region is rare. We report the case of a 65-year-old man with history of RCC, presented 7 years after nephrectomy, adrenalectomy and lung metastasectomy for his primary tumour, with symptoms of nasal obstruction, postnasal drip, productive cough and pressure sensation in the left maxillary sinus. CT revealed a unilateral, irregular opacification in the left maxillary sinus with bony erosion of the infraorbital canal wall. A yellow cystic lesion was completely removed from the maxillary sinus during functional endoscopic sinus surgery and histopathological analysis confirmed the diagnosis of a metastatic RCC. Patient continued to be managed with his pre-existing treatment for advanced RCC.
肾细胞癌（RCC）转移至头颈部区域较为罕见。我们报告一例65岁男性患者，有RCC病史，在因原发性肿瘤行肾切除术、肾上腺切除术及肺转移瘤切除术后7年出现症状，表现为鼻塞、鼻后滴漏、咳痰及左侧上颌窦有压迫感。CT显示左侧上颌窦单侧不规则混浊，眶下管骨质侵蚀。在功能性鼻内镜鼻窦手术中，从上颌窦完全切除一个黄色囊性病变，组织病理学分析确诊为转移性RCC。患者继续接受针对晚期RCC的原有治疗。
