On immunohistochemical evaluation, the tumor cells were positive for Vimentin, CD68, CD34, Nestin, GFAP, Desmin, SMA, AE1/AE3, and S-100 protein, but were negative for NSE, Synuclein, NeuN, EMA, pituitary hormones (LH, FSH, ACTH, TSH, growth hormone, and prolactin), synaptophysin and chromogranin. Here, VIM is linked to neoplasm.
