Laryngeal metastasis 7 years after radical nephrectomy.

Metastasis of renal cell carcinoma to the head and neck, especially the larynx, is an extremely rare event. Most previously reported cases have involved a presenting laryngeal lesion that lead to the discovery of an underlying primary renal cell carcinoma. Even more unusual is the occurrence of an isolated laryngeal metastasis revealing itself years after nephrectomy, with an interim of undetected recurrence. We believe this case to be the first reported example of an isolated supraglottic laryngeal renal cell carcinoma metastasis occurring 7 years after radical nephrectomy. Local excision of such isolated lesions seems to offer a favorable prognosis.
