[Scanning electron microscopic studies of the endometrium in premalignant hyperproliferative conditions].

Scanning electron microscopic study of endometrium in premalignant hyperproliferative conditions has been carried out. Scanning and transmission electron micrographs have been correlated. It has been established that changes of the surface pattern of cells within limits indicate the process of dedifferentiation. First of all formation of cilia can be regarded as a phenomenon demonstrating malignant transformation of cells. Surface pattern of cells and intracellular processes seems to show a certain degree of parallelism. To reveal morphologic criteria evidencing malignant transformation of cells further study of the problem is needed.
