Epithelioid angiosarcoma of the skin. A malignant tumor mimicking many different neoplasms.
Epithelioid angiosarcomas are rare malignant mesenchymal tumors. The main problem of these tumors is the complicate clinical and histological diagnosis. We report a case with an immunohistochemical panel. We propose the use of CD31 in the immunohistochemical panel of an undifferenciated tumor with epithelioid features, because it appears to be the only endothelial marker these tumors constantly express.
