Classification of leukemia

The etiology and pathogenesis cannot be the basis for classification of leukemia, because to date they remain outstanding. Therefore, in modern clinical Hematology use the classification of leukemia, built on gistogematicheskie principle.
In this classification reflects the edge of the form L, received a distribution on the principle according to maternal cells from each other in the process of differentiation. In the classification included eritremia, which according to modern views should be referred to the group of L. If erythremia is a kind of bone marrow hyperplasia, consisting of pre-emptive replacement fat bone marrow myeloid tissue with increased proliferation of erythrodermatous. The same transformation blood is in the spleen and liver.
In the classification does not refer to "monocytic leukemia", as the nosology of leukemia is based not so much on morphologically prevailing cellular elements in the peripheral blood, but on the characteristic features of the histogenesis of these cell element. It is well known that the leukemia has received its diagnostic autonomy, not because in the peripheral blood is dominated by lymphocytes, and due to the fact that this disease is lymphocytopenia hyperplasia and metaplasia in the blood system.
When the so-called monocytic leukemia in case if in the peripheral blood is dominated by Mature monocytes, histogenesis of them is characterized, as a rule, hyperplasia due reticular cells or geohistorical. Therefore more reasonable interpretation of these cases as one of the variants of reticulata.

Classification scheme leukemia
A. Form with leukemic infiltration caused by anaplasia undifferentiated blood cells B. Form with leukemic infiltration caused by anaplasia cells in the blood sprouts
I. Retikulez: 1) diffuse - acute, subacute, mainly anemic component; 2) with tumorous growths - acute, subacute, chronic (retikulez, chlamydia, gigantopithecus lymphoma); 3) paraproteinemias retikulez - myeloma, macroglobulinemia valdenstroma
Transitional forms: retikulez-genocidalists, retikulez-lymphocytic leukemia, retikulez-myeloma, retikulez-chlamydia
II. Genocidalists: acute, subacute
Transitional forms: genocidalists-retikulez,
genocidalists-erythromelas, genocidalists-mielolakoz

I. myeloid leukemia: subacute to chronic Transitional form: myelogenous leukemia-genocidalists-retikulez (blastny kriz)
II. Lymphocytic leukemia: acute, chronic
Transitional form: leukemia-retikulez
III. Eritremia: chronic Transitional forms: eritremia-myelofibrosis, eritremia-genocidalists-retikulez (blastny kriz)
IV. Megakaryocytic leukemia (primary thrombocythemia): subacute, chronic
