Metastatic Renal Cell Carcinoma Presenting a Maxillary Mucosal Lesion as a First Visible Sign of Disease: A Case Report and Review of Literature.

Renal cell carcinoma (RCC) is the third most common cancer that metastasizes to the oral and maxillofacial region following breast and lung cancers. Metastatic involvement in the oral cavity is rare and can present as a diagnostic challenge due to non-specific clinical features that mimic other benign or malignant conditions. The limited information available regarding oral metastasis of RCC highlights the importance of recognizing this uncommon presentation.
