Leukemic infiltrates: Vincent F, Rev Mal Respir 2012
Pulmonary leukostasis
Leukemic infiltration
Lysis pneumopathy
Pulmonary leukostasis: ALI
 Quantitative
 “Pulmonary hyperviscosity”
 Rapidly growing hyperleukocytic AML.
 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.

Poumon leucémique: prise en charge
 Infiltration pure:
 VNI, chimiothérapie classique,
 inhibition de l’adhésion du monoblaste sur l’endothélium
pulmonaire (DXM?)
 Leucostase ou leucostase + infiltration:
 Essai de VNI, cytoréduction (Hydréa)
 DXM?
 Poumon de lyse (DAD)
 Intubation et optimisation des échanges gazeux
 Attendre et éviter l’infection

Three major advances:
- Leukemic infiltrates
- Non invasive diagnostic strategy
- ARDS
Five evidence in the literature
 Heterogeneous (at least) disease
 Few positive trials, good negative trials
 Clinical – pathological discrepancies
 Berlin Definition
 Scarce data
ARDS and neutropenia
 Funny paradox (Frederic Ognibene)
 Pathophysiology
 Infection / infiltration / toxicity
 Used to be associated with poor outcomes
 Neutropenia recovery
