Ultrastructural characteristics of the parenchymatous and stromal components and their interrelationship in breast cancer

: Ultrastructure of the epithelial components of mammary carcinoma is well studied; detection of the organ and tissue specific features enables the differential diagnostics with tumours of different histogenesis both in the metastatic nodes and in the mammary tumour tissue. Moreover, establishing a certain complex of the electron microscopic features for separate histological variants of mammary carcinoma favours the differential diagnostics between them. Including the ultracytochemical methods into the investigation complex will give an opportunity to clarify the role of some enzymes in he tumour growth. A detailed study of the mammary carcinoma stromal component will help in determining the function of tumour tissue.
