[Leiomyosarcoma of the larynx. One case report].

The leiomyosarcoma of the larynx is a neoplasm extremely odd, only 46 cases are reported in the literature. We present a case seen in our Department. A male patient, 39-year-old, smoker, snoring and respiratory insufficient, who showed a whitish mass, 2.5 cm, round, steady on the right vocal fold. Urgent tracheostomy was performed but afterwards the patient refused new surgery. Biopsy revealed a malignant tumour of fusiform cells, validating as diagnostic through immunohistochemical analysis, a leiomyosarcoma case. Five months later the patient was seen again and a total laryngectomy performed. Eleven months after surgery the patient is alive and no signs of recurrence detected. In this paper diagnosis and treatment of leiomyosarcoma is discussed.
