Mesenchymal amyloidosis (a. mesenchymalis) is a rare systemic disease of unknown etiology, characterized by the deposition of amyloid in the cells of the reticuloendothelial system, as well as in various organs and tissues.
The disease occurs predominantly in young and middle-aged people, more often in men. Clinically manifested by enlargement of the liver, spleen, lymph nodes; kidney damage with the development of nephrotic syndrome and renal failure. In the blood - anemia, leukopenia, thrombocytopenia.
The diagnosis is confirmed by the detection of amyloid in biopsies of the affected organs. Treatment is usually ineffective. The prognosis is serious due to the progressive course and development of end-stage renal failure.
