Renal cell carcinoma: A rare metastasis to the tongue--a case report.

UNLABELLED: This paper describes the diagnosis and treatment of a patient who presented with a lesion on the left posterior scalp, who was also experiencing more generalized signs of malaise. Biopsy led to the diagnosis of renal cell carcinoma and additional lesions developed in the tongue. About 1% of all malignancies found in the oral cavity are metastatic. CLINICAL RELEVANCE: Metastases to the head and neck are uncommon but should always be considered among the differential diagnoses of lesions.
