Paranasal sinuses and nose metastasis are very uncommon. About 50 have been reported. Renal cell carcinoma is the primary neoplasm which most frequently metastasizes in the nasosinusal region, followed by breast and lug. Symptoms are unspecific, but the epistaxis constitutes the most common sign due to the significant vascularizations of the tumor. Prognosis is poor. The survival rate fluctuates between 15-30% at 5 years. Surgery is the elective treatment.
鼻窦和鼻部转移非常罕见。据报道约有50例。肾细胞癌是最常转移至鼻窦区域的原发性肿瘤，其次是乳腺癌和肺癌。症状不具特异性，但由于肿瘤有丰富的血管，鼻出血是最常见的体征。预后较差。5年生存率在15%至30%之间波动。手术是首选治疗方法。
