| gliosarcoma | A glioma consisting of immature, undifferentiated, pleomorphic, spindle-shaped cells with relatively large, hyperchromatic, frequently bizarre nuclei and poorly formed fibrillary processes. It is sometimes used as a term for a malignant neoplasm derived from connective tissue (e.g., that associated with blood vessels in the brain) in which there are proliferating glial cells.
