Abstract

Abstract: Background: Pediatric Chronic Myeloid Leukemia (CML) is a rare entity accounting for 2-3% of pediatric malignancies. CML rarely presents as Blast Crisis (BC) at the time of diagnosis, and megakaryocytic blast crisis is even rarer.
Case Presentation: We herein, report a case of a young female, 10-year-old who presented with anemia, leukocytosis and massive
splenomegaly. Clinical features, peripheral film and bone marrow findings were consistent with CML in megakaryocytic blast crisis. Bone marrow cytogenetic analysis revealed karyotype of 46, XX, t(9:22)(q34;q11.2) in 20 metaphases and BCR-ABL P210 by PCR was detected with transcript level of 83%, which further confirmed our diagnosis.
Conclusion: De novo presentation of chronic myeloid leukemia with megakaryocytic blast crisis is rarely observed in pediatric population with very few cases published till now. We are presenting this case because of its rarity, likelihood of misdiagnosis as AML (M7) and poor prognosis, if not treated precisely.
