A case of laryngeal leiomyosarcoma and review of the literature.

Leiomyosarcoma (LMS) of the larynx is a very rare malignancy that originates from blood vessel, smooth muscle or from the heterotopic mesenchymal tissue in the larynx. The histological diagnosis of LMS depends on the immunohistochemical investigation. The case is here presented of an 82-year-old man with shortness of breath and hoarseness. Indirect laryngoscopy showed a pedunculated large glottic lesion causing airway obstruction. Direct laryngoscopy was performed and biopsies were taken. From the pathological examination, the diagnosis of LMS was made. This case is presented of laryngeal LMS with the clinical, radiological, and histological findings.
