Figure 4a.  (a) Low-power photomicrograph (original magnification, x20; hematoxylin-eosin stain) demonstrates a cystic hemorrhagic area (arrows). (b) High-power photomicrograph (original magnification, x100; hematoxylin-eosin stain) shows a highly vascular clear cell cortical adenoma (arrows) adjacent to the cystic hemorrhagic area deforming the normal architecture of the adrenal gland.
