Bilateral and multifocal Warthin's tumor of parotid gland: two case reports and review of literature.
نویسندگان
چکیده
Warthin's tumor is the second most common benign neoplasm of the parotid. Most of cases are represented by a single localization, while only a small percentage of patients presents bilateral lesions or unilateral multifocal pattern. Warthin's tumor has an excellent prognosis due to the low rate of recurrence after surgical treatment. Malignant transformation occurs in less than 1% of cases. The aim of this article is to present two unusual cases of Warthin's tumor and an updated review of the latest scientific literature.
