[Comparative study of degrees of differentiation of endometrial cancer]

Electron micrographs and scanning electron micrographs of well differentiated and anaplastic carcinoma of endometrium have been compared. It was established, that the grade of malignancy could be correctly estimated by studying the surface pattern of them. Comparison of the surface pattern of cells with the ultrastructure of the intracellular elements has shown that they represent functional unit. The surface pattern of cells may characterize intracellular processes and indicate the grade of differentiation.
