Abstract

Metastases of malignancies to the parotid region are relatively infrequent (21%-42% of all malignant tumors 1 ), but metastases of infraclavicular origin are infrequent (0.16%-4% 1,2 ). From 1986 to 1998, only 17 cases of parotid metastases of renal clear cell carcinoma were documented in the literature reviewed. In this paper we report a case of a patient with a parotid tumor which was the first manifestation of distant disease. It was only once the tumor was surgically removed that the histopathology allowed the diagnosis of the primary tumor; namely a renal clear cell adenocarcinoma.
