Malignant fibrous histiocytoma is a connective tissue tumor containig fibroblast-like cells and histiocyte. It is one of the most common types of soft tissue sarcoma of late adult life but, the involvement of head and neck area is relatively rare. Although adequate modalities of treatment is performed, the prognosis of the tumor itself is not clear. Because of its highly malignant property and, as in cases of other regions of the body, devastating result would occur and aggressive treatment is required. Malignant fibrous histiocytoma shows variable histologic appearance, and may be classified into several subtypes(storiform- pleomorphic, myxoid, giant cell, inflammatory, angiomatoid) and the storiform-pleomorphic type is the most common type. The authors have recently experienced a case showing good clinical result to the present, after total maxillectomy and split thickness skin graft and postoperative radiotherapy(6400cGy) in the malignant fibrous histiocytoma involving the right maxillary sinus, so report this case with a review of literature.
