Histologic and immunohistochemical studies in ACC. (A) Hematoxylin and eosin-stained section highlights a diffuse proliferation of rounded cells with abundant cytoplasm, compatible with adrenocortical neoplasia. (B) Ki67 (RRID:AB_2335949; https://antibodyregistry.org/search.php?q=AB_2335949) staining shows increased expression, > 10%, with regional heterogeneity. (C) SF1 (RRID: AB_2894906; https://antibodyregistry.org/search.php?q=AB_2894906) staining shows diffuse and strong nuclear positivity.
