A Case Report Of Bilateral Warthin's Tumor

ABSTRACT

tumor is a benign neoplasm that occurs almost exclusively in the parotid gland. The tumor most frequently occurs in the tail of the parotid near the angle of the mandible. One unique feature of Warthin's tumor is the tendency of bilateral occurrence, which has been noted in 4 to 7 percent of cases. Most of these bilateral tumors do not occur simultaneously but are metachronous(occurring at different times).Histologically the tumor is composed of a mixture of ductal epithelium and a lymphoid stroma. Surgical removal is the treatment of choice for patients with Warthin's tumor. Warthin's tumor seldom recurs after removal. In our department, a 50-year old man,diagnosed as Warthin's tumor by fine needle aspiration biopsy, was treated by superficial parotidectomy on right side and subtotal parotidectomy on left side. For the treatment of Warthin's tumor, correct pretreatment diagnosis and the selection of appropriate surgical methods are important. We present a case report of the bilateral Warthin's tumor with the review of literatures.
