(C) Positive immunohistochemical staining for oligodendrocyte lineage transcription factors (Oligo) (Envision method × 200). (D-E) Malignant meningioma. (D) Several tumor cells were distributed extensively and appear obviously atypical and mitotic (H&E × 200). (E) Immunohistochemical staining showing epithelial membrane antigen (EMA) (Envision method × 200).
