Pharyngeal fibrovascular polyp in a child.

Fibrovascular polyp of the upper aerodigestive tract is an uncommon tumor that may present in pediatric patients with symptoms ranging from dysphagia to asphyxiation and death. We present a unique case of a pediatric patient with an asymptomatic fibrovascular polyp noted as an incidental finding on a cervical ultrasound evaluation. This lesion extended from the posterior tonsillar pillar and prolapsed freely into the nasopharynx and esophagus. The literature relevant to this case is reviewed, and the etiology, pathophysiology, and management principles are discussed.
