Corticosteroids may stimulate the release of neutrophils from the marrow and slow or prevent the leukoerythronlastic of neutrophils from the circulation. Leukemoid reactions may be secondary to benign or malignant conditions.

Normal mature neutrophils contain small amounts of leukocyte alkaline phosphatase LAP in primary granules. Leukoerythroblastic reactions suggest possible extramedullary hemtopoiesis and is often secondary to piicture cancer. Neutrophilia may be due to a number of acute and chronic causes: Leukostasis results from sludging of high numbers of leukocytes in small vessels, particularly the brain, lungs, and kidneys.


A leukocytosis is frequently accompanied by cytologic abnormalities, such as toxic granulation or Dohle bodies discussed later in this section.

Increased basophils are associated with polycythemia vera and extramedullary hematopoiesis. Leukoerythroblastosis was defined as pichure presence of immature red and white cells in peripheral blood by Vaughan inand regarded as circulating expression of hematological and non- hematological malignancies.
