[Malignant fibrohistiocytoma in otorhinolaryngology. Review of two cases].
Fibrohistiocytomas are soft-tissue tumors of histiocytic origin that have a variety of histological patterns. Although cases of malignant fibrohisticytoma (MFH) of the head and neck have been reported with increasing frequency in recent years, they can be considered rare. However, they probably are more frequent than thought because of the different designations that the disease has received and confusion among clinicians and pathologists regarding these tumors. We report two cases of MFH of the tonsil and larynx, respectively. The histopathological diagnostic criteria, therapeutic indications, and prognosis evaluation are described.
