Extension of nasopharyngeal lymphoma to the middle and external ear.

We describe a patient with nasopharyngeal lymphoma who was admitted for chemotherapy. At admission, otoscopic examination revealed a large polyp occluding the left external ear canal. The polyp was removed, and histopathologic examination showed the same tumor that was found previously in the nasopharynx. Magnetic resonance imaging showed an infiltrative process that involved the left side of the nasopharynx and extended toward the left middle and external ear. To our knowledge, this is the first case report of a direct extension of nasopharyngeal lymphoma into the middle and external ear.
