A hairy polyp is an uncommon developmental malformation that is usually found in the oronasopharynx before the patient's first birthday. Despite its rarity, it is the most common congenital nasopharyngeal mass.1 The number of cases reported has risen sharply in the last 10 to 15 years, most likely because of the capacity for better examination (flexible endoscopy, computed tomography, and magnetic resonance imaging) rather than because of an actual increase in incidence.
