Tongue metastasis as an initial manifestation of metastasis in renal cell carcinoma: A case report

Renal cell carcinoma (RCC) has unpredictable and diverse behavior. The classic triad of hematuria, loin pain and abdominal mass is uncommon. About 25-30% of patients are found to have metastases at the time of diagnosis. Bones, lungs, liver and brain are the frequent sites of metastases. RCC with metastasis to the oral cavity is rarest manifestation. We report a case of 35 years old male who underwent radical nephrectomy for localized RCC six years back, now presented with mass in the base of tongue which was suspected as carcinoma of tongue; subsequently was confirmed as metastatic RCC following excisional biopsy and was treated with intra-oral electron radiation therapy.
