Abstract：
Metastatic lesions to the paranasal sinuses and skull base, while rare, carry a poor prognosis. Renal cell carcinoma has been reported in multiple case reports to be one of the most common distant malignancies to spread to the paranasal sinuses; however, it is often unrecognized by physicians, and thus treatment is delayed. To increase awareness of this disease process, we describe three cases of metastatic renal cell carcinoma to the sinonasal cavity, which is the largest case series in the literature to date.
摘要：
鼻旁窦和颅底的转移性病变，虽然罕见，预后不良。据报道，在多个病例报告中，肾细胞癌是扩散到鼻旁窦的最常见的远处恶性肿瘤之一；然而，它通常不被医生识别，因此治疗被延迟。为了提高对这种疾病过程的认识，我们描述了3例转移到鼻腔的肾细胞癌，这是迄今为止文献中最大的案例系列。
