A typical case of gliosarcoma in a 74 year-old woman is reported. The exact origin of sarcomatous areas of this tumor has been a matter of debate. Our immunohistochemical findings, using a panel of antibodies (GFAP), vimentin, keratins, F-VIII related antigen, muscle specific actin, KP-1 and HMB-45), support its undifferentiated nature. The literature concerning this topic is reviewed and briefly discussed.
