[Leiomyosarcoma of the larynx: presentation of a case].

The authors report a new case of laryngeal leiomyosarcoma. The patient was a 43-year-old-man. The tumor extended to the left vocal cord, the paraglottic space and the deep layers of the left false vocal cord. Histologically, the lesion showed the typical pattern of a grade-3 leiomyosarcoma. Immunochemical studies revealed a strong positive staining with the actin smooth muscle antisera. A partial laryngectomy was performed. There was no evidence of recurrent or metastatic disease 10 months after surgery.
