Abstract:
In leukemoid reactions, there is a distinct reactive and therefore nonmalignant leukocytosis with immature stages of granulopoiesis.
Clinical picture:
Leukemoid reactions occur mostly in severe acute and chronic infections. The leukemoid reaction occurs more often in children. The leukemoid reaction must be distinguished from chronic myelocytic leukemia.
Hematology:
Metamyelocytes and myelocytes are present in the peripheral blood. This is usually associated with leukocytosis (> 20 x 109/L). Normal or low leukocyte values in the course of a leukemoid reaction suggest failure of myelopoiesis.
