Metastatic lesions represent 18% of all malignant tumors of the mouth and jaws, which are regarded as rare sites of metastases from different primary tumors. metastases in mouth soft tissue are also rare, and within these it is on the gums where they more frequently occur. primary tumors which metastasize to the mouth are most commonly: lung, breast, and kidney. clear cell carcinoma is the most frequent cancer of the kidney (6080% of cases). this tumor has a great propensity to metastasis. we report a case of a 45yearold man with renal cell carcinoma in which the gingival symptoms (metastatic tumor) preceded the discovery of the primary lesions.
