[Myelomonocytic leukemia in childhood (author's transl)].

Report of five cases of juvenile myelomonocytic leukemia; authors describe an hemopathy of the young child with important splenomegaly, hepatomegaly and adenopathies; anemia with erytroblastemia; hyperleucocytosis with myelemia and monocytosis, rich and granulous bone marrow. Also remarkable is evolution, as it fatal outcome often occurs before a two year evolution, without remission looking like acute myeloblastic leukemia, a few patients have remission of most the symptoms, ending in an apparent recovery, which may be spontaneous.
