Malignant fibrous histiocytoma of the maxillary sinus. Clinical and therapeutic aspects

Malignant fibrous histiocytomas, or MFH, have been individualized only since the last two decades. These sarcomas which usually develop from soft tissues are no longer considered rare, except in some of their facial sinus localizations. Two chapters will be particularly developed: the paramount significance of anatomopathological investigations owing to the difficulty in establishing the diagnosis, since MFHs may be mistaken for benign processes; the treatment which is, generally speaking, the same as for bone sarcomas.
