In response to inflammation or other stimuli, neutrophils move leukoerythrobblastic the marginating or storage pool into the circulating peripheral blood. Leukostasis results from sludging of high numbers of leukocytes in small vessels, particularly the brain, lungs, leukoerythroblawtic kidneys.

Leukemoid reactions are characterized by blasts, promyelocytes, myelocytes, and metamyelocytes in the peripheral blood. Leukoerythroblastosis due to infections can resemble leukemia, differential diagnosis can be difficult.

Journal List Iran J Pediatr v. Because of the extremely elevated leucocyte count with monocytosis, circulating immature myeloid cells and nucleated red blood cells RBCs chronic juvenile myelomonocytic leukemia JMML was suspected and bone marrow aspiration performed. This div only appears when the trigger link is hovered over. A leukocytosis is frequently accompanied by cytologic abnormalities, such as toxic granulation or Dohle bodies discussed later in this section.

Differential diagnosis of leukemoid reactions should be made with leukemias and other causes such as infections, hemorrhage, drugs, hypersensivity syndrome, myeloid growth factors, malignancy and splenectomy [ 1 – 3 ]. Most users should sign in with their email address. Thus bone unable to be remodelled, replaces hematopoietic marrow space, leading to extramedullary hematopoiesis and spillage of hematopoietic elements into the peripheral blood. Next bone marow reserves are shifted into the peripheral blood and finally marrow production is increased.
