Renal cell carcinoma, which has clear cells in 70% of cases, has a high frequency of hematogenous distant metastases to lung, bone, liver, and other areas. Metastatic cancer accounts for 1 to 3% of malignant tumors in the stomatognathic region, and the metastasis of renal cell carcinoma to the oral mucosal tissue, though extremely rare, does occur. In addition, clear cells have been observed in some salivary gland cancers in the oral cavity. Therefore, the differential diagnosis of metastatic renal cell carcinoma and salivary gland cancer is important. This review discusses the differential diagnosis between metastatic renal cell carcinoma and malignant tumors of the salivary gland.
肾细胞癌在70%的病例中含有透明细胞，血行远处转移至肺、骨、肝及其他部位的频率较高。转移性癌占口腔颌面部恶性肿瘤的1%至3%，肾细胞癌转移至口腔黏膜组织虽极为罕见，但确实会发生。此外，在口腔的一些唾液腺癌中也观察到了透明细胞。因此，转移性肾细胞癌与唾液腺癌的鉴别诊断很重要。本文综述讨论了转移性肾细胞癌与唾液腺恶性肿瘤之间的鉴别诊断。
