    Peripheral Blood Smear in Chronic-Phase Chronic Myelocytic Leukemia

    In chronic-phase chronic myelocytic leukemia, the peripheral blood smear is characterized by a constellation of abnormalities including a striking leukocytosis with pronounced neutrophilia and basophilia, and, frequently, eosinophilia. Although myeloid elements in all stages of maturation are present, blasts account for < 5% of all leukocytes. Most patients have thrombocytosis, and platelets are often enlarged and pleomorphic.
