aCML is a leukemic disorder with myelodysplastic as well as myeloproliferative features. It is characterized by principal involvement of the neutrophil series with leukocytosis comprised of immature and mature neutrophils that are dysplastic. Mutilineage dysplasia; however, is common and reflects the stem cell origin.
