[Granular cell tumor localized in the glottis in children. Apropos of a case].

We report the first case of adult granular cell tumor form localized in the glottis in a 8 year-old girl. The first symptom was a chronic dysphonia. Examination with rigid optic demonstrated an irregular yellow hypertrophic lesion in the posterior third of the left vocal fold. The lesion was removed by CO2 laser micro-spot under general anesthesia. There has been no recurrence after 15 months of follow-up and the postoperative voice quality is satisfactory regarded both objectively as subjectively. Granular cell tumors are rare. The histogenesis is still badly known. Enzymological and electron microscopy studies seem to indicate a nervous origin (Schwann cells). Treatment is surgical. Wide local excision is the general rule for limited lesions with easy access. When bigger lesions are present in more vital structures such as trachea or oesophagus, surgery has to be more cautious.
