title: Oral metastasis of renal cell carcinoma, presentation of a case.
abstract: The oral cavity constitutes a site of low prevalence for metastasis of malignant tumors. Nevertheless, it has a high prevalence for metastasis of renal origin. Besides the kidneys, there are other primary sites with high prevalence of metastasis to the oral mucosa, such as the lungs, skin and breasts. Metastasis is common in patients with a background of treated renal tumors, thereby, it is proper to determine the possibility of oral metastasis as part of the protocol of attention. However, it constitutes a diagnostic challenge when it presents in patients with no renal antecedents. It is in this type of patients that the diagnosis of carcinoma is achieved by means of a metastasis. Survival rate in these patients is short because at the time of the metastasis diagnosis, the general compromise is high. The following report describes a case referred from the Rheumatology Unit with an intraoral tumor, that was finally diagnosed as a Metastasic Renal Cell Carcinoma with multiple metastasis.
