Glioblastoma with a primitive neuronal component. a Dyshesive malignant cells of relatively small size contain nuclei with granular chromatin and inconspicuous nucleoli, and display synaptophysin reactivity (inset) in a left parotid gland FNA (Papanicolaou-stained cytocentrifuge slide ×63 oil; inset: immunohistochemistry ×40). b Identical morphological features including synaptophysin reactivity (inset) are present in the prior surgical resection of the left temporal brain tumor (HE-stained tissue section. ×63 oil; inset: immunohistochemistry ×40). FNA, fine-needle aspiration.
