With clinical vigilance and laboratory tests of platelet and coagulation factor function, the clinician can promptly recognize and treat hemostatic disorders in leukemic patients. For example, laboratory values are strikingly abnormal in disseminated intravascular coagulation. Prompt neutralization of the underlying cause of the coagulopathy is essential. ⋯ Immune thrombocytopenic purpura may be easy to diagnose when the reduction in the circulating platelet count is compared with the normal number of marrow megakaryocytes. But attempts to increase platelet count by platelet transfusions may be frustrating. Treatment involves high doses of corticosteroids, followed by splenectomy if necessary.
