The malignant histiocytosis is for the first time described in 1939 by R. Century of Scott and A. N. T. of Robb-Smith. The disease is initially tumoral process with defect in system of the englobing macrophages. Mainly adult are ill, is more rare — children of advanced age. Hereditary aspects are not revealed. On clinical and pathomorphologic signs the malignant histiocytosis has a certain similarity to a histiocytosis of X, especially with Letterer's illness — Ziva. Development of a disease is caused by proliferation of macrophagic elements in various fabrics — a liver, a spleen, lymph nodes, skin, marrow. Unlike a histiocytosis of damage of a bone tissue it is not observed. Pathomorphologic substrate is provided by atypical histiocytes, multinucleate cells meet. An important differential diagnostic character is existence in cytoplasm of fagotsitirovanny erythrocytes, leukocytes and thrombocytes. Cells of a malignant histiocytosis differ in the expressed tumoral anaplaziya though studying of markers shows that they belong to histiocytic elements. The disease arises sharply and it is very difficult to catch early symptoms. The condition of patients considerably worsens — appetite disappears, loss in weight progresses. The sharp weakness, high temperature, a dermahemia, papulo-makulezny rash sometimes accepting hemorrhagic character, necroses of skin and mucous membranes are noted. The considerable gepatosplenomegaliya is typical; bodies at a palpation dense, and at fast increase — are painful. Damage of a liver can lead to development of jaundice and ascites further. At many patients lymph nodes increase. The hyperplasia is moderate, nodes dense, painless. Specific pulmonary and cordial changes are shown by exudative pleurisy and a pericardis. In blood — increase in SOE, a leukocytosis. Anemia is constantly noted. Development of anemia is caused both by damage of marrow, and a hemolitic component. The quantity of reticulocytes is increased, normocytes meet. In a late stage of a disease the pancytopenia develops. In some cases at blood there are atypical histiocytes. In marrow — the progressing infiltration histiocytic elements with phagocytosis signs. Differential diagnosis needs to be carried out with a histiocytosis of X. The malignant histiocytosis distinguishes lack of bone destructions and existence of the anaplazirovanny histiocytes englobing erythrocytes, leukocytes and thrombocytes. The disease is characterized by a rapid malignant current. The forecast is adverse. Carry out complex treatment: corticosteroids in combination with cytostatic drugs (Vincristinum, 6 Mercaptopurinum, Cyclophosphanum); symptomatic means, antibiotics, transfusions of components of blood, disintoxication therapy.
