Schwannoma : Verocay Bodies
Frequently, the Schwann cells in Antoni A areas show nuclear palisading, whorling patterns, and Verocay bodies. Verocay bodies are formed by a highly ordered arrangement of Schwann cell nuclei in rows separated by fibrillary processes as nicely illustrated here. A few benign glandular elements are also seen in this image. These are not entrapped normal structures but represent true epithelial differentiation within the tumor.
