minimally differentiated acute myeloblastic leukemia (M0);
acute myeloblastic leukemia, without maturation (M1);
acute myeloblastic leukemia, with granulocytic maturation t(M2)
promyelocytic, or acute promyelocytic leukemia (APL) (M3)
acute myelomonocytic leukemia (M4)
acute monoblastic leukemia (M5)
acute erythroid leukemias (M6)
