Figure 3: (a) Histopathology showing a cellular tumor exhibiting pale nodular areas surrounded by densely packed hyperchromatic cells (HE, ×100; ×200). (b) Histopathology showing densely packed cells with round to oval or carrot-shaped hyperchromatic nuclei surrounded by scanty cytoplasm, occasional neuroblastic rosettes, and brisk mitosis (HE, ×400). (c) Reticulin stain showing reticulin free pale islands surrounded by dense intercellular reticulin fi ber network (×200); tumor cells showing strong immunopositivity for synaptophysin and neuron-specifi c enolase (×400)
