Bilateral and multicentric Warthin's tumor primarily presented with cervical lymph node involvement

Papillary cystadenoma lymphomatosis (Warthin's tumor) is the second most common benign neoplasm of the parotid gland. Although the tumor usually presents as a slowly growing mass in the tail of the parotid gland, extraparotid involvements such as the cervical lymph nodes may be observed rarely. In this article, we aimed to report a Warthin's tumor case with atypical presentation. A 68-year-old male patient with the history of smoking was admitted to our clinic with the complaint of right-sided neck lump. After physical examination and imaging, excisional biopsy was performed with an initial diagnosis of cervical lymphadenopathy. Pathology result was reported as Warthin's tumor. Five months later, multicentric Warthin's tumor in the contralateral parotid gland was diagnosed and operated. With this case report, we want to emphasize that Warthin's tumors may rarely present as a neck lump outside the parotid gland, and we want to review relevant literature data.
