Acute promyelocytic leukemia (APL) is a special subtype of acute myeloid leukemia (AML) with M3 morphology and specific chromosomal translocation t(15;17) with resultant leukemogenic PML-RARalpha fusion gene. Its main characteristics are therapy response using all-trans-retinoic acid (ATRA) and its high rate of recovery; higher than other subtypes of acute myeloid leukemia. Arsenic trioxide induces a high complete remission rate in patients having an APL relapse. Experience in the use of this drug is still limited in the field of Paediatrics.
