The Ki-67 labeling index is extremely low (less than 1%). ---- Not shown: A neurofilament stain highlights axons predominantly at the periphery of the lesion, consistent with a combined solid and infiltrative growth pattern. The tumor cells and rosettes are mostly not NF immunoreactive. The tumor cells are negative for Neu-N.
