Abstract:
Two typical cases of epithelioid sarcoma were examined by immunohistochemical stain using antibodies to epithelial membrane antigen, carcinoembryonic antigen, vimentin and cytokeratin. Both cases showed positive reactivity for the four kinds of antibodies. These results point to the fact that epithelioid sarcoma simultaneously expresses epithelial markers and characteristic mesenchymal phenotypes. Epithelioid sarcoma appears to be a tumor derived from a multipotential mesenchymal cell with multidirectional differentiation.
