ISOLATED METASTASIS OF RENAL CELL CARCINOMA TO THE LARYNX: A CASE REPORT

Abstract

A 55-year-old man underwent right radical nephrectomy after the diagnosis of right renal cell carcinoma (RCC). He did not show any relapse or metastasis for 3 years and 5 months after surgery. He was admitted to the hospital in April 2014 with a throat discomfort. Laryngoscopy revealed a 5 mm supraglottic mass. The tumor was locally excised and pathology revealed metastatic RCC. While RCC frequently metastasizes to the lungs, bones, lymph nodes, and brain, an isolated metastasis of RCC to the larynx is an extremely rare event. We report a case of isolated RCC metastasis to the supraglottic larynx 3 years and 5 months after radical nephrectomy.
