presence of immature leukocytes and immature erythrocytes in the
blood
occurs in marrow replacement disorders such as MYELOFIBROSIS correct
answers leukoerythroblastic reaction
morphologically normal, pathologically abnormal because of enzyme
deficiency that results in an ability to degranulate which causes inhibited
