Minimally differentiated acute myeloblastic leukemia is a subtype of AML. It is classified as M0 by FAB. It represents 2–3% of all cases of AML. Although minimally differentiated AML was recognized earlier, criteria for FAB M0 were developed in 1987. The blasts in these cases cannot be recognized as myeloid based on morphology and cytochemistry, but immunophenotyping demonstrates myeloid antigens.
