title: Synchronic nasopharyngeal and intraparotid warthin tumors: A case report and literature review.
abstract: Warthin tumor is the second most frequent benign salivary gland tumor after pleomorphic adenoma; it occurs almost exclusively in the parotid gland and peri-parotideal lymph nodes, although it may rarely present in other locations. It may be multicentric and bilateral in a small percentage of cases. Nasopharyngeal Warthin tumor is very rare, and the presence of a synchronic WT involving nasopharynx and parotid is an exceptional event, as it has been described only twice in the literature. In this article we report an additional case of a synchronic Warthin tumor and review the related literature. Key words:Warthin tumor, synchronic WT, multicéntrico, nasopharynx.
