[Granular cell tumor of the larynx in the child. Case report].

Laryngeal tumors are uncommon in children, accounting only for 2% of the laryngeal anomalies. Ninety-eight percent are benign; the most frequent ones are recurrent respiratory papillomatosis and haemangioma. Granular cell tumor, also called Abrikossoff tumor, is an unusual benign neoplasm, especially in the larynx. Clinical manifestations depend on the size and location of the tumor. Dysphonia is the main presenting symptom. The diagnosis is confirmed by the biopsy. The treatment of choice is surgery. We present a 9-year-old girl with dysphonia and exertion dyspnea due to a granular cell tumor of the larynx, and we emphasize the importance of considering the endoscopic evaluation of the airway in every child with progressive or persistent dysphonia in order to determine the etiology.
