Abstract:
:Fine-needle aspiration biopsies from three patients with neuroblastoma were studied by light microscopy, and the morphologic findings were correlated with those from transmission and scanning electron microscopy. Light microscopic examination of the aspiration smears from all three cases revealed small and large round cells with variable numbers of intertwining cytoplasmic processes. Transmission electron microscopy confirmed the light microscopic finding of cytoplasmic processes; in addition, it revealed the presence of other diagnostic morphologic features, including neurosecretory granules, microtubules, and synaptic cell junctions. Scanning electron microscopy demonstrated that the tumors were composed of a mixture of undifferentiated round cells and more differentiated cells with long cytoplasmic processes. The morphologic spectrum of these processes and their interrelationships with one another and with other cells could be studied in detail. These findings indicate that scanning electron microscopy may be used effectively in the morphologic evaluation and pathologic diagnosis of neuroblastoma.
