UNUSUAL METASTASIS OF A HYPERNEPHROMA - CASE-REPORT AND LITERATURE-REVIEW

Background: The occurrence of metastasis of renal cell carcinomas in t he head and neck region is extremely rare. Metastasis in the larynx, h ypopharynx, and the nasal sinuses has been reported. We report here ab out a 55-year-old female with metastasis in the soft palate and tonsil , which occurred 10 years following tumor nephrectomy. Results and Con clusions: The incidence of metastasis in renal cell carcinomas can be observed even many years following initial curative treatment of the p rimary tumor. Although rare in the region of the head and neck, they c an often be mistaken for benign tumors such as hemangiomas or inflamma tory tissue. The treatment of choice is radical surgical resection.
