[2] Warthin's tumor primarily affects older individuals (age 60–70 years).

The tumor is slow growing, painless, and usually appears in the tail of the parotid gland near the angle of the mandible.

Smokers are at 8 times greater risk of developing Warthin's tumor than the general population.

There are cystic spaces surrounded by two uniform rows of oncocytes, which are epithelial cells with abundant, granular, eosinophilic cytoplasm.

[citation needed] The differential diagnosis includes sebaceous lymphadenoma and oncocytoma.
