Histopathological features represent the hallmark of this tumor type, which are characterized by a diffuse growth of oligo-like and multinucleated cells, with nuclear clusters disposed as “pennies on a plate.” Tumor cells display diffuse positivity for OLIG-2 and synaptophysin, focal positivity for Neu-N and MAP2, and negativity for GFAP. Here, RBFOX3 is linked to neoplasm.
