Periadrenal schwannoma. (A) Photomicrograph of hematoxylin and eosin (H&E)-stained slide at low magnification shows hypercellular Antoni A areas of spindle cells with abundant eosinophilic cytoplasm with wavy nuclei and vague pallisading. (B) Photomicrograph of H&E-stained slide at low magnification shows hypocellular Antoni B areas of scattered spindle cells in an abundant myxoid stroma. (C) Photomicrograph of H&E-stained slide at low magnification shows the well demarcated spindle cell neoplasm (*) arising from the nerve sheath of an adjacent periadrenal nerve fiber (arrow).
