Neurocytoma-like and neuroblastoma-like lesions. (a) Hematoxylin-eosin (HE) staining showed an oligodendroglioma-like halo in the limited region. (b) The lesion corresponding to figure (a) was diffusely positive for glial fibrillary acidic protein. (c) HE staining showed tumor cells arranged in parallel rows. (d) The lesion corresponding to figure (c) was strongly positive for tubulin, βIII isoform in a parallel fashion. (a-c: ×400; d: ×200).
