[Granular cell tumor: an infrequent cause of dysphonia in childhood].
Granular cell tumors (GCT) are rare and usually benign tumors whose histogenesis is debated. The skin, subcutaneous tissues, and mucosae of the head and neck are areas of predilection for GCT. Laryngeal involvement is uncommon, but may create diagnostic and therapeutic problems when it occurs. Laryngeal GCT are decidedly uncommon in children, only 17 cases having been reported in the literature. A case of GCT of the larynx in an 11-year-old girl is reported. The presenting symptom was hoarseness. The macroscopic tumor and hoarseness disappeared after chemotherapy (EVAIA) for Ewing sarcoma of the knee.
