A 66-YEAR-OLD man presented with a 1-week history of otalgia and otorrhea. He was diagnosed as having otitis externa and was treated accordingly. At presentation, a visible oval 2 × 3-cm-diameter mass was discovered in the right parotid region, adjacent to the mandible. The mass, which was painless, had a stony consistency and was fixed to the mandible. The patient's medical history was unremarkable.
The results of a cranial nerve examination were normal, and there were no other palpable neck or parotid masses. Fiberoptic nasoendoscopy of the nasopharynx and laryngopharynx did not reveal any focal abnormalities. Fine-needle aspiration cytology was performed, but the aspirate was acellular. A second cytological examination was performed 2 weeks later, with the same result. The computed tomographic scan is shown in Figure 1.
