Facial nerve palsy associated with Warthin's tumor

A solid parotid mass and an ipsilateral facial weakness is nearly pathognomonic for a malignant parotid neoplasm. There are only a few documented cases in the world's literature of nonmalignant parotid lesions causing facial paralysis. A case is presented of a Warthin's tumor causing a facial palsy. Extensive areas of necrosis, inflammation, and fibrosis surrounding branches of the facial nerve may have accounted for the facial palsy.
