We report a case of non-functioning adrenal cortical carcinoma (ACC) presenting with metastatic disease to the tongue, which is an extremely uncommon onset for this neoplasm. Histologically, the lesion had the appearance of an anaplastic neoplasm, and a panel of immunohistochemical markers including vimentin, MART-1, S100 protein, HMB-45, smooth muscle actin, common muscle actin, desmin, CD31, CD34, CD68, EMA and cytokeratins, was helpful in excluding melanoma, as well as other mesenchymal and epithelial neoplasms.
