Four embryonal rhabdomyosarcomas, one tumor diagnosed as an undifferentiated sarcoma, probably a rhabdomyosarcoma, and six different non-muscular sarcomas were investigated with antibodies specific for different intermediate filament types. The tumor cells in the rhabdomyosarcomas and the undifferentiated tumor were stained clearly by antibodies to desmin, the intermediate filament type characteristic of muscle. The staining of tumor cell by antibodies to vimentin, the intermediate filament type characteristic of certain cell types of mesenchymal origin including myoblasts, was different in these 5 cases. In one case of embryonal rhabdomyosarcoma nearly all tumor cells were stained, but in the remaining cases few or no tumor cells were positive with the vimentin antibody. In these rhabdomyosarcomas not only the large rhabdomyoblasts, but also the small undifferentiated cells were labeled by antibodies to desmin. In the latter cell type the desmin filaments were arranged typically in coils. In contrast, tumor cells in the non-muscular mesenchymal sarcomas were stained only by antibodies to vimentin but not by antibodies to desmin or prekeratin. The retention of the desmin marker characteristic of normal muscle in cases of rhabdomyosarcoma not only allowed the undifferentiated desmin-positive sarcoma to be classified as rhabdomyosarcoma but also suggests that the use of antibodies to desmin could be very helpful in the future for the diagnosis of undifferentiated rhabdomyosarcomas.
