3.3 Acute myeloid leukaemia

The blood smear on Slide 4 comes from a person who has acute myeloid leukaemia. Myeloid cells are the immature form of leukocytes and would not normally be found in the blood. Usually, they would develop in the bone marrow into neutrophils, basophils or eosinophils. However, in leukaemia there is overproduction and large numbers of myeloid cells are seen in the blood.
