title: Malignant schwannoma of the ethmoid sinus associated with AIDS.
abstract: We have presented an uncommon case of a low-grade malignant schwannoma arising in the ethmoid sinus in a patient with AIDS. The use of the nasal endoscope provides a safe, expedient way to diagnose nasal and paranasal sinus neoplasms. This case demonstrates that peripheral nerve sheath tumors must be included in the differential diagnosis of sinus masses in patients with AIDS.
