Parotid metastasis from renal cell carcinoma: a case report and review of the literature.

Abstract

Renal cell carcinoma metastasis to the parotid gland after tumour nephrectomy is extremely rare. Herewith a review of the literature on this topic is discussed and a case report is presented of a 69-year-old man affected by parotid localization of renal clear cell carcinoma with neck lymph node metastases and involvement of the masseter muscle 2 years after nephrectomy. When an otolaryngologist encounters a parotid mass, diverse differential diagnoses have to be considered. A high level of suspicion of metastatic disease from the specific primary site will help in achieving correct diagnosis and evaluation of the extension of the disease. Surgical resection, even enlarged parotidectomy with neck dissection, should be considered as a therapeutic option for exclusive location of the disease in the head and neck.
