Multiple Warthin Tumors With Epithelial–Myoepithelial Carcinoma of the Ipsilateral Parotid Gland: A Case Report

Abstract

Multiple primary tumors of the parotid gland refer to the occurrence of 2 or more primary tumors in the ipsilateral or bilateral parotid gland metachronously or synchronously, which do not originate from postoperative recurrence or metastasis. Multiple primary tumors of the parotid gland, especially synchronous benign and malignant tumors, are extremely uncommon. A rare case of multiple Warthin tumors with epithelial–myoepithelial carcinoma of the ipsilateral parotid gland is reported as follows.
