Pale (78%), fever (64%), pain (32%), hepatomegaly (38%), lymphadenopathy (28%), splenomegaly (26%), patients with anemia (82%), leukocytosis (38%), thrombocytopenia (54%). The highest types were ALL–LI (68%), SR-ALL (54%), and remission outcome reached 82%.Conclusion: Insidence higher in male, aged 1,5 – 10 years old, malnourished at the start of the diagnosis.
