Lymphangiomatous polyp of the nasal cavity: a rare presentation.

Lymphangiomatous polyp of the nasal cavity is a very rare condition. We are reporting a case of a unilateral nasal mass presenting with noisy breathing during sleep, change of voice, watery nasal discharge, and anosmia in a 5-year-old boy. The mass was removed via a transnasal endoscopic approach, and a diagnosis of lymphangiomatous nasal polyp was established by histopathology.
