Asphyxia Caused by a Giant Fibrovascular Polyp of the Esophagus.

Fibrovascular polyps (FVPs) are rare, benign tumors of the esophagus; they usually appear as an intraluminal mass within the esophagus, which can grow and reach enormous sizes if left untreated. They can cause a variety of symptoms, from mild dysphagia to life-threatening asphyxia. Diagnosis is challenging because FVPs can resemble any respiratory condition, which can lead to misdiagnosis and potentially dangerous therapies.
