Results of histopathological and immunohistochemical investigation of left adrenal and liver biopsy specimens (magnification, x200). Microscopic appearance (hematoxylin and eosin, HE, staining) showed eosinophilic tumor cell cytoplasm, nuclear atypia, diffuse architecture, and sinusoidal invasion. Immunohistochemical staining showed strong positive reactivity for SF-1, P450c17, 3betaHSD2, P450c21, CYP11B1, and CYP11B2 and partial positive reactivity for P450scc and 3betaHSD1 in both the left adrenal tumor (upper panel) and the liver tumor (lower panel). The DHEA-ST test result was negative for both specimens.

Immunohistochemical investigation showed strong positive staining for SF-1, P450c17, P450c21, 3betaHSD2, CYP11B1, and CYP11B2 and partial positive staining for P450scc and 3betaHSD1 in both the ACC and the liver metastases (Figure 2); these findings indicated synthetic capability for aldosterone and cortisol.
