Fig. 3. A: The resected lesion comprised monomorphous tumor cells with moderate cellularity (hematoxylin and eosin staining, original magnification ×100). B: Some areas showed oligodendroglioma-like tumor cells with perinuclear halos and distinct cytoplasmic borders (hematoxylin and eosin staining, original magnification ×400). C: There was angiocentric arrangement of tumor cells around focally hyalinized vessels (hematoxylin and eosin staining, original magnification ×200). D: Immunohistochemistry of glial fibrillary acidic protein revealed strong positivity in the tumor cells with cytoplasmic processes (immunohistochemistry, original magnification ×200). Fig. 3.
