A Rare Cause of Nasal Obstruction: A Solitary Neurofibroma

This case represents a peripheral nerve sheath tumor as a cause of nasal obstruction. Nerve sheath tumors are relatively uncommon; however, most otolaryngologists will encounter them. These tumors develop from cranial and spinal nerve roots and from peripheral nerves. In total, approximately 25% to 44% of nerve sheath tumors occur in the head and neck region. Although the most important are cranial nerve tumors—the majority being acoustic neuromas arising from the vestibular nerve—they may also develop in the nasal cavity.
