Although fatal pulmonary complications frequently occur during the course of acute leukemia, a minor proportion of the complications are due to leukemia itself. Infections, drug reactions and concomitant medical conditions are the major causes of respiratory distress in leukemic patients. We treated four patients with acute myeloid leukemia complicated by leukemic cell lysis pneumopathy (LCLP). All of the patients had leukemia of monocytoid origin and their respiratory function deteriorated soon after chemotherapy initiation. Although two of the patients required mechanical ventilation, all four improved after continued chemotherapy. Our experience indicates that, in cases of LCLP, chemotherapy should be continued with maximal respiratory support.
