Renal metastases from a squamous cell carcinoma of the larynx.

摘要

Laryngeal squamous cell carcinoma (SCC) tends to exhibit local spread with a low incidence of distal metastases. The majority of distal metastases are to the lungs and renal involvement is extremely rare. We present a case of laryngeal SCC with metastatic spread to the left kidney presenting as a large, mainly cystic mass. The radiological differentiation of renal metastases from primary renal tumours is discussed.
