title: [A clinical and pathological study of gliosarcoma].
abstract: In order to study the clinicopathological features, histogenesis and prognosis, 12 cases of gliosarcoma were reported representing 0.4% of a series of 2743 patients undergoing biopsy for CNS tumors. All the tumors originated from the cerebral hemispheres with a predilection for the temporal lobes. Half of the cases show more firm consistency and are rather well demarcated from brain tissue. Clinically, they are sometimes mistaken for meningiomas. Of the 10 patients with follow-up, 9 have died. The mean survival period after operation was 8 months, 1 cases is still alive and well for 3.2 years. There were some cases in which the origin of spindle cell populations could not be determined by H & E staining. Glioblastoma and malignant fibrous histiocytoma (MFH) element of the tumor was confirmed by electron microscopical examination and immunohistochemical stains for GFAP, Mac 387, VIM, FV III RA, etc. Osteosarcoma component in the tumor was detected in one case. It was accepted that MFH arose from the primitive uncommited mesenchyme.
