Leukostasis during Chronic Myelogenous Leukemia Resolved Following Leukapheresis

: Patients with hyperleucocytic leukemia (WBC count>10×10(4) mL) are at high risk of early mortality owing to pulmonary or cerebral leukostasis. Several researchers have reported the efficacy of immediate leukapheresis. Here, we report of a patient with chronic myelogenous leukemia in blast crisis and with pulmonary failure due to leukostasis who recovered after a combination therapy of leukapheresis and imatinib treatment.
