(a) Hematoxylin-Eosin: large neuronal cells can be seen between small round oligodendrocytes. (b) ATRX immunohistochemical staining: a diffuse staining is present in neoplastic cells. (c). Chromogranin immunohistochemical staining: An intense granular pattern is expressed in large neuronal cells. (d) CD34 immunohistochemical staining: neither small oligodendrocytes nor large neuronal cells expressed this marker. Scale bars: 75 mum (a-c); 150 mum (b and d).

Larger ganglion-like cells showed expression of synaptophysin and chromogranin-A, but no CD34 expression [Figure 1].
