Signs and symptomsedit

Warthin's tumor primarily affects older individuals age 60–70 years There is a slight male predilection according to recent studies The tumor is slow growing, painless, and usually appears in the tail of the parotid gland near the angle of the mandible In 5–14% of cases, Warthin's tumor is bilateral, but the two masses usually are at different times Warthin's tumor is highly unlikely to become malignant

Locationsedit

The gland most likely affected is the parotid gland In fact, it is the only tumor virtually restricted to the parotid gland Though much less likely to occur than pleomorphic adenoma, Warthin's tumor is the second most common benign parotid tumor

Causeedit

Its cause is unknown, but there is a strong association with cigarette smoking Smokers are at 8 times greater risk of developing Warthin's tumor than the general population2

Diagnosisedit

The appearance of this tumor under the microscope is unique There are cystic spaces surrounded by two uniform rows of epithelial cells with centrally placed pyknotic nuclei The cystic spaces have epithelium referred to as papillary infoldings that protrude into them Additionally, the epithelium has lymphoid stroma with germinal center formation

The differential diagnosis includes sebaceous lymphadenoma and oncocytoma

Treatmentedit

Most of these tumors are treated with surgical removal It is non recurrent
