Adrenal neuroblastomas; histological and immunohistochemical characterization. Tumors originated in the adrenal gland and were grossly solid, homogeneous mases (Panel A). Histologically the tumors were composed of sheets of round cells exhibiting nuclear pleomorphism and scant cytoplasm (Panel B, hematoxylin and eosin). By immunohistochemistry, the majority of neoplastic cells showed robust expression of T-Antigen (Panel C), and wild-type p53 (Panel D). (All panels original magnification ×400).
