Histology and immunohistochemistry furtherly confirmed the benign adrenocortical adenoma with immunohistochemistry positive for inhibin α, melan A, β-captenin, SYN (focal), Ki-67(< 3%), and negative for chromogranin (CgA), cytokeratin (CK), S-100, P53. This evidence concerns the gene TP53 and adrenal cortex adenoma.
