[Unusual metastasis of renal cell carcinoma. A case report with review of the literature]

Abstract

Background: The occurrence of metastasis of renal cell carcinomas in the head and neck region is extremely rare. Metastasis in the larynx, hypopharynx, and the nasal sinuses has been reported. We report here about a 55-year-old female with metastasis in the soft palate and tonsil, which occurred 10 years following tumor nephrectomy.

Results and conclusions: The incidence of metastasis in renal cell carcinomas can be observed even many years following initial curative treatment of the primary tumor. Although rare in the region of the head and neck, they can often be mistaken for benign tumors such as hemangiomas or inflammatory tissue. The treatment of choice is radical surgical resection.
