Constant if >200 000/mm3. Endothelial injury and activation from microvascular invasion related to hyperviscosity, leukocytic microthrombi, oxygen steal and hypoxia. Clinical manifestations of leukostasis Central nervous system circulation Headache, confusion, somnolence, dizziness, slurred speech, impaired hearing, tinnitus, diplopia, delirium, stupor, coma Retinal vein distension, retinal hemorrhage, papilledema Intracranial hemorrhage Penile circulation Priapism Cardiovascular system Acute myocardial infarction Right ventricular overload Acral lividosis Rapidly rising white-cell count Cell type (monoblasts) A postmortem examination revealed profound leukostasis in the heart, lungs, adrenal glands, liver, and spleen. Sludging of high numbers of leukocytes in small vessels (brain, lungs, and kidneys) Leukemic pulmonary infiltrates Blasts are aggregated in vascular lumens The infiltrates typically follow the lymphatic routes along the bronchovascular bundles, interlobular septa, and pleural interstitial tissue. Lysis pneumopathy: DAD Occurs immediately or early after chemotherapy Diffuse alveolar damage LEUKEMIC INFILTRATION leukemic infiltration of the alveolar capillaries LEUKOSTASIS Filling of a pulmonary artery with leukemic cells, as well as leukemic infiltration of alveolar capillaries.
