[Leiomyosarcoma of the larynx. Review of the literature apropos of a case].

Leiomyosarcoma of the larynx is extremely rare, only 21 cases were reported in the literature. The authors report a personal case in a 26 years old patient treated by a total laryngectomy and analyse all cases of the literature. It comes in relative young man (42 years old) in regard to the others ORL localisations. There is not tobacco relation. The lymph node extension is rare however the distant metastasis are frequent specially in lung. The treatment is based on surgery, the neck lymphadenectomy is possible in patients with cervical lymph nodes. The Leiomyosarcoma is a resistant tumor to the irradiation and chemotherapy however the postoperative irradiation is justified. The prognosis of this tumor is reserved on account of local recurrences and distant metastasis.
