Figure 3: (a) HandE stained ×40 photomicrograph of the specimen showing a predominantly cystic tumor bounded by fibroconnective tissue capsule. The tumor was composed of Antoni A areas of compact spindle cells with focal nuclear palisading and few Antoni B areas of spindle to ovoid cells in a loosely textured matrix. Stroma showed many dilated thick-walled vessels and hemorrhage. (b) ×200 photomicrograph showing typical S-100 immunoreactivity of the schwannoma.
