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 highprevalence for metastasis of renal origin. Besides the kidneys, there are other primary sites with high prevalence ofmetastasis 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 thepossibility of oral metastasis as part of the protocol of attention. However, it constitutes a diagnostic challengewhen it presents in patients with no renal antecedents. It is in this type of patients that the diagnosis of carcinomais achieved by means of a metastasis. Survival rate in these patients is short because at the time of the metastasisdiagnosis, the general compromise is high.The following report describes a case referred from the Rheumatology Unit with an intraoral tumor, that was finallydiagnosed as a Metastasic Renal Cell Carcinoma with multiple metastasis (AU)
