{Abstract}: Invasive ductal carcinoma of no special type is the most common type of breast cancer. In light of the above, many authors have reported the histological and electron microscopic characteristics of these tumors. On the other hand, a limited number of works exist where the authors have concentrated on investigating the extracellular matrix. This article presents data received as the results of light and electron microscopic examination of the extracellular matrix, angiogenesis, and cellular microenvironment of invasive breast ductal carcinoma of no special type. The authors have shown that the processes of stroma formation in the IDC NOS type are associated with the presence of fibroblasts, macrophages, dendritic cells, lymphocytes, and other cells. It was also shown the detailed interaction of the above cells with each other, as well as with vessels and fibrillar proteins such as collagen and elastin. The microcirculatory component is characterized by histophysiological heterogeneity, which manifests as the activation of angiogenesis, relative vascular differentiation, and regression of individual microcirculation components.
