Representative H and E stained sections of the histological subtypes of glioma included in this study. Left, diffuse astrocytoma, characterized by relatively low cell density and highly pleomorphic nuclei. Middle, oligoastrocytoma, characterized by mixed features of astrocytoma and oligodendroglioma. Right, oligodendroglioma, characterized by a distinctive clear protoplasmic area, relatively round bland nuclei, and high cell density
