Microscopic section from a 47-year-old female with a pilocytic astrocytoma of the brainstem, showing a cellular pilocytic zone that demonstrates typical piloid cells with interdigitating processes. Classic Rosenthal fibers are visible in the center of the field as elongated, rod-shaped, eosinophilic bodies. (Hematoxylin-eosin; x400) (Contributed by Dr. Herbert Newton.)
