title: Primary intracranial malignant fibrous histiocytoma--ultrastructural study.
abstract: Malignant Fibrous Histiocytoma is the most common soft tissue sarcoma in adults with the majority of cases that occur in patients between 50-70 years and 64% of cases occurs in male. Most commonly it arises in extremities (lower 49% and upper 19%), less often in the abdomen (16%) and very rare in head localization (3%) [5]. Typically macroscopically it is a multilobulated, gray-white, fleshy mass between 5-20 cm of diameter. In light microscopy this tumour has a highly variable morphologic pattern and manifests a broad range of histological appearance. It has been classified into the following subtypes: storiform-pleomorphic, myxoid, giant cell, inflammatory and angiomatoid. The first two subtypes are more frequent than others. The aim of this report is to present the electronmicroscopic features of giant cell type of MFH localized in head.
