In infants a leukoerythroblastic reaction suggests severe hemolytic anemia, such as erythroblastosis fetalis shown below. In response to inflammation or other stimuli, neutrophils move from the marginating or storage pool into the circulating peripheral blood.

Most patients recover; leukoerythroblaztic, some develop adult T cell leukemia. Neutrophilia may be due to a number of acute and chronic causes: In leukemoid reaction anemia and thrombocytopenia are usually not expected.

What does Leukoerythroblastic Reaction mean? Definition, meaning and sense

Nucleated red cell and early myelocyte. All lekuoerythroblastic results excluded leukemia. Thus bone unable to be remodelled, replaces hematopoietic marrow space, leading to extramedullary hematopoiesis and spillage of hematopoietic elements into the peripheral blood. Leukemoid reactions are characterized by blasts, promyelocytes, myelocytes, and metamyelocytes in the peripheral blood.

Two nucleated red cells and promyelocyte. 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.

Infectious lymphocytosis is characterized by a lymphocytosis of small lymphocytes, generally Increased basophils are associated with polycythemia vera and extramedullary hematopoiesis. Other viral causes of lymphocytosis include infectious lymphocytosis and HTLV-1 related transient lymphocytosis.

Malignant or benign leucocytosis.
