[Acute monocytic leukemia as secondary neoplasia in a girl with acute lymphocytic leukemia]. / Leucemia monocítica aguda (LMA-M5) como segunda neoplasia en una niña con LLA-L1.

ABSTRACT

The presence of second malignancies in children suffering from acute lymphoblastic leukemia (ALL) is becoming increasingly frequent. Nevertheless, the appearance of M5 type acute myeloid leukemia (AML) in patients being treated for ALL is very rare. We report the presence of AML-M5 as a second malignancy in a girl diagnosed of ALL-L1 56 months before. The clinical course of this rare association is discussed.
