Cancer metastases to the oral cavity are reported infrequently. Renal cell carcinoma has a high metastatic potential, with approximately one third of patients presenting with metastatic disease. New lesions in the oral cavity often rely on preoperative biopsy to establish the diagnosis. However, we report an unusual case in a setting of known renal cell carcinoma disease, where initial pathology and culture data were misleading. Appropriate follow-up and a high index of suspicion will remain necessary. Surgical excision is the treatment of choice.
