(a) Normal adrenal cortex parenchyma (arrow) invaded by tumor (hematoxylin-eosin ×40). (b) Tumor composed of short fascicles and storiform patterns of spindle or epithelioid cells with oval-round nuclei and eosinophilic fibrillary cytoplasm. Increased mitosis is also seen (arrows) (hematoxylin-eosin ×100). (c) Slit-like spaces and extravasated red blood cells within the tumor cells (hematoxylin-eosin ×200). (d) PAS positive intracytoplasmic hyaline globules in some tumor cells (circle) (×400). (e) Epithelioid tumor cells with nuclear atypia and pleomorphism (hematoxylin-eosin ×400). (f) Foci of necrosis are present in some areas (hematoxylin-eosin ×200).
