The myeloid leukocytoses

In this article, qualitative and quantitative aspects of the "benign" myeloid leukocytoses are discussed. Although leukemia has been excluded from the discussion, it is clear that the so-called benign myeloid leukocytoses may on occasion reflect malignant disease--notably of the solid tumor variety. Absolute counts, left shifts, and leukemoid reactions are reexamined and their diagnostic nuances analyzed.
