Renal cell carcinoma presenting as a solitary thyroid nodule.

An unusual case of renal cell carcinoma of the right kidney with a solitary thyroid metastasis as the only presenting symptom is reported. Right thyroid lobectomy was done followed by right radical nephrectomy. A solitary metastasis of the renal cell carcinoma has a much better prognosis than the usual stage IV tumours and an aggressive management with radical nephrectomy and excision of the solitary metastasis is advocated.
