[Acute promyelocytic leukemia in the west of Venezuela]

Twenty-nine cases of acute promyelocytic leukaemia of children and adults are reported. This figure represents 13.61% of all the acute leukaemias and 27.88% of the acute non-lymphoblastic leukaemias found in Zulia State between 1982 and 1987. Those findings mean a higher frequency than reported in other childhood as well as adult series. So, Zulia State appears as an important geographic area for the occurrence of this type of leukaemia.
