Antrochoanal polyp (ACP) is a benign unilateral polyp that originates from the maxillary sinus and extends through the accessory or natural ostia into the nasal cavity and choanae. Its etiopathogenesis is still poorly understood. The clinical presentation is dominated by nasal obstruction and rhinorrhea, but in severe cases dysphagia, epistaxis or dyspnea may also be present. Diagnosis is mainly clinical, supported by computed tomography (CT) scan, and treatment is mainly based on endoscopic surgery. We report a case of Killian's polyp in a 17-year-old boy revealed by dysphagia and we study the clinical, paraclinical, anatomopathological characteristics, therapeutic management and evolutionary profile of the antrochoanal polyp.
