Cellular composition and cytoarchitectonics of lymphoid formations in the mucosa of human ureters in mature, elderly and senile ages

By means of microscopy with differential staining of connective and lymphoid tissues there was studied the structure of lymphoid tissue, “associated” with the mucosa in the wall of the ureters in men and women during the stages of ontogenesis. It is shown that the mucosa in the wall of the ureters undergoes age-related restructuring, which are characterized by qualitative and quantitative changes of its components: elastic, reticular, collagenous fibers and cells of the lymphoid order. The boundaries of involutive processes in the mucosa of the wall of the ureters were studied. The cell composition of the lymphoid neoplasms and their cytoarchitectonics in men and women mature, elderly and senile age was represented in this article.
