Simultaneous squamous cell carcinoma with leiomyosarcoma of the larynx.
OBJECTIVE
To present the first reported case of a simultaneous squamous cell carcinoma with a leiomyosarcoma of the larynx, our treatment of the patient, and the 9-month follow-up results.


METHODS
Case study.


METHODS
Review of diagnostic studies, the operative technique, and the patient's chart for the 9-month period after treatment.


RESULTS
A case with double laryngeal tumors with simultaneous evolution but different histological patterns is described. The squamous cell carcinoma and leiomyosarcoma involved both the vocal cords and the anterior commissure. A partial laryngectomy was performed, and the patient has been free of disease for 9 months.


CONCLUSIONS
Multiple laryngeal tumors are exceedingly rare. To our knowledge, no previous reports of a simultaneous squamous cell carcinoma and a leiomyosarcoma of the larynx have been reported. Both tumors were not invasive in this case, so conservation surgery was feasible.
