[Malignant fibrohistiocytoma of the larynx]. / Fibrohistiocitoma maligno de laringe.

The paper deals with 2 malignant fibrohistiocytoma cases sitting on the larynx, one of them associated with a laryngeal cancer "in situ". These are uncommon growths particularly in this location, of difficult anatomopathologic diagnosis. Placing of these exceptional tumors were the epiglotis and piriform sinus. The treatment of choice is a large resection alone or followed with radiotherapy, at least that is the opinion shared by several authors.
