The immunohistochemistry stain of the tumor (inhibitin +, Melan-A +, synaptophysin +, vimentin + and AE1/AE3+) supported an adrenocortical origin rather than a renal or mesenchymal origin, which was in accordance with preview reports.[13,14] Therefore, a pre-operative biopsy of the tumor, if possible, should be performed to confirm the diagnosis of ectopic adrenocortical adenoma and provide evidence for clinical treatment. This evidence concerns the gene SYP and neoplasm.
