Pathology of Stromal-Vascular Dystrophy (mesenchymal, extracellular degenerations) develops as a result of metabolism disorder in the connective tissue and is identified in the stroma of organs and the vascular wall. Development of Stromal Vascular Dystrophy occurs in the gistion. Gistion is complex, which includes the microvasculature with the surrounding elements of connective tissue: ground substance, fibrous structures, and connective tissue cells. In the case of metabolism disorder, there is an accumulation of metabolism products, which are brought with the blood and lymph, or may be accumulated due to perverted synthesis, in the intercellular substance. Morphogenetic mechanisms of Stromal Vascular Dystrophy are such mechanisms as infiltration and perverted synthesis of substances. Causes of Stromal Vascular Dystrophy according to pathology , are infectious and allergic diseases, rheumatic diseases, diseases of blood circulatory system, in particular, multiple myeloma;
