Background:
Acute lymphoblastic leukemia is the most common childhood cancer, with an 80% frequency in children between 1 and 10 years old. The outcome and prognosis of acute lymphoblastic leukemia in children depends on various factors, such as age, clinical and biological features, and cytogenetic factors.
Case Presentation:
We report the case of a pediatric patient, a 4-year-old Moroccan female who was referred to the Hematology and Oncology Department of 20 August 1953 Hospital in Casablanca and diagnosed with B-cell acute lymphoblastic leukemia associated with a rare genetic chromosomal abnormality.
Conclusion:
Translocation (1;4)(p21;p15) is a relatively rare chromosomal abnormality found in human leukemia and was never described isolated in pediatric B-cell acute lymphoblastic leukemia patients. It showed a good evolution by complete remission and recovery of this patient after receiving all chemotherapy and after 8 years of follow-up.
