| The procedure which may be used to assist in differentiating chronic myelocytic leukemia from leukemoid reaction is: | View Page |
| The cells included in the composite image were found in a peripheral blood smear with a total WBC of 24,500/mm3. The differential count was:
myelocytes 1
metamyelocytes 4
band neutrophils 15
segmented neutrophils 40
monocytes 8
eosinophils 2
basophils 1
lymphocytes 29.

| A large percentage of the neutrophils on the peripheral blood smear of a young man are similar to those in the photograph.They most likely represent what condition: | View Page |
| The neutrophils illustrated in this photograph are representative of those seen in the smear. The total WBC was 28,500 cells/cumm. The appropriate report to be issued following a morphology consultation would be: | View Page |
| Typical cells on a peripheral blood smear as photographed here were repeatedly encountered as the smear was reviewed. The peripheral white blood cell count was 51,000/ml with an orderly maturation sequence. The comment "leukemoid reaction" may properly be appended to the report. | View Page |
| Leukemoid reaction revisited The term leukemoid reaction is used to describe peripheral white blood cells that on the stained blood smear may have some resemblances to leukemia cells. Quantatively in a leukemoid reaction, the neutrophil count is >50,000 cumm with more immature cells, particularly myelocytes, than are usually present in toxic left shift syndromes. The presence of immature cells in a leukemoid reaction awakens thoughts of leukemia. Great care must be taken to make a distinct differentiation between aberrant white blood cell proliferations and a benign but exaggerated granulocytic proliferative response. Our material is from a 1-month-old girl with Down's syndrome. Her total white blood count was 37,000/mm3 interpreted as leukocytosis with left shift. Leukocytosis with a left shift, and leukemoid reactions with high alkaline phosphatase are conditions to be mindful of in patients with Down's syndrome. The alkaline phosphatase score is high in leukemoid reactions, low in granulocytic leukemia. | View Page |
