Synchronous Tumors of the Parotid Gland: Presentation of 3 Cases and a Review of the Literature
AbstractSynchronous tumors of the parotid gland are two or more neoplasms originating from different sites of the gland, making up less than 1% of all parotid tumors, most frequently as Warthin tumors at more than one site. In this study, 3 cases of synchronous parotid tumors out of 193 parotid surgeries performed between 2004-2010 in our clinic will be presented with their clinical, radiological and histopathological findings, and discussed according to the current literature. The first case was diagnosed as synchronous parotid tumor in composition of pleomorphic adenoma and Warthin tumor. The second case was Warthin tumor at 2 different sites, and the third case was a salivary duct carcinoma with Warthin tumor. Synchronous tumors, despite being rare, are remarkable as they can affect the prognosis and should be kept in mind during the differential diagnosis of parotid tumors.
