Oral squamous cell carcinomas (OSCC) and Warthin tumors are relatively common lesions that are encountered in patients who present with head and neck tumors. However, synchronous occurrence of these two tumors is a rare phenomenon. This report describes a 61-year-old patient with a squamous cell carcinoma of the right side of his buccal mucosa, who received extensive surgery including bilateral neck dissection. Histopathological examination of the neck dissection, however, revealed a Warthin tumor of the right parotid gland. It is important to be aware of such a presentation of Warthin tumor to avoid overtreatment for OSCC.
