Warthin's Tumor,a Multifocal Disease

Abstract

Of all salivary gland neoplasms Warthin's tumor is the only lesion which is truly multicentric. The most common presentation of these multiple lesions is bilateral solitary masses. We present the first reported case of bilateral multiple tumors occurring simultaneously. The embryology of the salivary glands as it relates to the pathogenesis of this tumor is discussed. The differential diagnosis of the multinodular parotid gland is reviewed.
