Metastatic Clear Cell Renal Cell Carcinoma Presenting with a Gingival Metastasis

Metastatic deposits to the oral cavity are exceptionally rare. The commonest tumor types metastasizing to the oral cavity include lung and breast carcinoma. Renal cell carcinoma is believed to be the third most common infra clavicular tumor to metastasize to the head and neck. We report a case where an oral cavity deposit was the initial presentation for an occult clear cell renal carcinoma. Additional therapeutic options, including immunotherapy, tyrosine kinase inhibitors, and participation in a clinical trial, should be discussed with the patient despite the poor overall prognosis.
