[Ultrastructure of malignant fibrosarcoma].
Electron microscopic examinations of two malignant fibroxanthomas revealed some ultrastructural features characteristic of this tumor. The tumor elements were represented by histiocyte-like, fibroblast-like and little differentiated cells. In some of the latter the signs of macrophage differentiation could be seen and therefore a possibility of their transformation into histiocytes is assumed.
