On immunohistochemistry, the tumor was strongly positive for vimentin, CD10, focally positive for epithelial membrane antigen, melan-A and negative for TTF-1, S100, inhibin and synaptophysin (Figure 4) The positive vimentin and negative inhibin results weighed against the likelihood of an adrenocortical tumor. This evidence concerns the gene VIM and adrenal cortex neoplasm.
