A solitary laryngeal neurofibroma ina pediatric patient.

A neurofibroma of the larynx is a rare disease that usually involves the arytenoids and the aryepiglottic fold. Pediatric patients with a laryngeal neurofibroma often present with progressive dyspnea. A definitive diagnosis of a laryngeal neurofibroma is based on the histopathologic demonstration of the characteristic spindle cells, and a positive result in immunohistochemical staining for S-100 protein. Tumor excision of laryngeal neurofibromas by an external approach was formerly common. We present a case of a solitary laryngeal neurofibroma in a 4-year-old child that was completely excised using direct laryngoscopy and a CO2 laser. There has been no recurrence after a follow-up of 4 years. For pediatric patients with an isolated laryngeal neurofibroma, endoscopic surgery provides an alternative approach due to its safety, effectiveness, and minimal invasiveness.
