Abstract

|
The salivary gland most frequently involved with secondary cancer is the parotid gland. Metastases are responsible for 21-42% of malignant parotid tumors. Malignant melanoma and squamous cell cancer are the two most common tumors to metastasizing to the parotid gland. Renal cell carcinoma takes up 85% of primary malignant renal tumors. It rarely metastasizes to the head and neck area. When metastasis to head and neck area occurs, it involves the gingiva, tongue, palate, parotid gland, uvlua, mandible, and lip. When tumorous areas arefound in the salivary gland consisting of clear cells, it is important to carry out differential diagnosis of various primary tumors with clear cells and metastatic renal cell carcinoma. In this paper, we report on a case of renal cell carcinoma which had metastasized to the parotid gland after a radical nephrectomy.
