In the FAB classification of leukemia, Acute Myelomonocytic Leukemia is:
a. M1
b. M2
c. M3
d. M4
e. M5
Which FAB classification is represented by the following data:
Blasts comprise 50% of the nucleated cells in the peripheral blood
30% of blasts are Peroxidase weakly positive
Most Blasts are non-specific esterase positive
All Blasts are specific esterase negative
a. M2
b. M3
c. M5
d. M6
e. M7
The FAB (French-American-British) classification of leukemia, Acute Myelomonocytic Leukemia is:
a. M1- Acute myeloblastic leukemia with minimal maturation,
b. M2- Acute myeloblastic leukemia with maturation,
c. M3- Acute promyelocytic lukemia,
d. M4- Acute myelomonocytic leukemia with eosinophilia,
e. M5- Acute monocytic leukemia.
Q. Blasts comprise 50% of the nucleated cells in the peripheral blood
30% of blasts are Peroxidase weakly positive
Most Blasts are non-specific esterase positive
All Blasts are specific esterase negative
a. M2- 30% of blasts are Peroxidase weakly positive
b. M3: Acute promyelocytic leukemia (APL)- Most Blasts are non-specific esterase positive,
c. M5: Acute monocytic leukemia- Blasts comprise 50% of the nucleated cells in the peripheral blood,
d. M6: Acute erythroid leukemia- 50% erythroid precursors of nucleated cells in BM, 20% myeloblasts of non-erythroid cells in BM,
e. M7: Acute megakaryoblastic leukemia- 50% of the blasts are megakaryocytic lineage.
