Multiple Benign Lymphoepithelial Cysts in Both Parotid Glands; A Case Report.

Parotid gland tumors are usually unilateral, and bilateral parotid gland tumors are rare, Warthin's tumor (adenolymphoma) being the most common. We present a case of bilateral multiple parotid gland tumors in a patient with Sjögren's syndrome. A 62-year-old female came to our department because of a slowly growing mass in the right parotid region. CT-scan and MRI showed multiple cystic lesions in both parotid glands. The masses on the right side were removed surgically, with preservation of the facial nerve. The histological diagnosis was benign lymphoepithelial cyst (branchial cyst). Benign lymphoepithelial cysts are usually unilateral and single. The findings in this patient are very unusual.
