Leukemoid reaction in a patient with acute lymphoblastic leukemia following the second chemotherapy

Öz

The occurrence of persistent neutrophilic leukocy­tosis above 50,000 cells/μL for reasons other than leukemia is defined as leukemoid reaction. Chronic myelogenous leukemia (CML) and chronic neutro­philic leukemia (CNL) should be excluded, and un­derlying diseases or causes should be examined, in differential diagnosis. The most commonly ob­served causes of leukemoid reactions are severe infections, intoxications, malignancies, severe hem­orrhage, or acute hemolysis [1]. J Clin Exp Invest 2013; 4 (2): 258-259.
