Although the French-American-British (FAB) classification has been replaced, it is still often referred to and provides a point of reference. Table 6 lists the FAB categories.
Table 6. AML FAB Classification.FAB Subtype | Name |
M0 | Undifferentiated acute myeloblastic leukemia |
M1 | Acute myeloblastic leukemia with minimal maturation |
M2 | Acute myeloblastic leukemia with maturation |

M4 | Acute myelomonocytic leukemia |
M4 eos | Acute myelomonocytic leukemia with eosinophila |
M5 | Acute monocytic leukemia |
M6 | Acute erythroid leukemia |

If you look back on the WHO classifications, you will see that a number of these names are listed under the WHO group "therapy related myeloid neoplasms."
