RT Journal Article SR Electronic T1 Monocytic leukemoid reaction, glucocorticoid therapy, and myelodysplastic syndrome JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 571 OP 574 VO 57 IS 6 A1 Moraes, Manoel A1 Wilkes, John A1 Lowder, James N. YR 1990 UL http://www.ccjm.org/content/57/6/571.abstract AB A leukemoid reaction is a complex and poorly understood response by the bone marrow to a variety of stresses; although any peripheral blood cell line may be involved, it is rarely a purely monocytic event. A case is reported of a true monocytic leukemoid reaction in a patient with myelodysplastic syndrome related to the effect of corticosteroids on the underlying marrow disorder.
