An 89-year-old woman presented with a rapidly progressive mass in the right parotid gland that extended into the middle cranial fossa. She denied constitutional symptoms, weight loss, and problems with speech, swallowing, or respiration. Her medical history was remarkable for liposarcoma of the right arm that had been treated with surgical resection 2 years earlier. Physical examination revealed a 3-cm fullness in the right preauricular area. There was no trismus, cranial nerve deficits, or neck lymphadenopathy.
