Figure 4. H&E stain shows the intact thyroid capsule ( shown by the arrow) and schwannoma separated by soft tissues
In histopathological examination of H&E stain , schwannoma have characteristic hypercellular Antoni A and hypocellular Antoni B areas. Within Antoni A areas, verocay bodies are seen which are bands of fusiform nuclei alternating with clear zones devoid of nuclei. Schwannoma are usually S-100 and Vimentin positive18as seen in our case.
