Summary
This study details a rare case of acute nonlymphocytic leukemia (FAB-M5) in a 9-year-old girl, characterized by a unique chromosome translocation, t(11;23)(q21;p11). The findings highlight a novel genetic marker in pediatric leukemia.
Area of Science:
- Hematology
- Cytogenetics
- Pediatric Oncology
Background:
- Acute nonlymphocytic leukemia (FAB-M5) is a rare subtype of leukemia.
- Genetic abnormalities play a crucial role in leukemia development and prognosis.
- Understanding rare chromosomal translocations is vital for advancing leukemia research.
Observation:
- A 9-year-old female patient presented with symptoms of acute nonlymphocytic leukemia (FAB-M5).
- Peripheral blood analysis revealed low hemoglobin, normal white blood cell count with 10% blasts, and reduced platelet count.
- Bone marrow aspirates showed 36.7% blasts and the presence of micromegakaryocytes.
Findings:
- The patient exhibited a rare chromosome abnormality: t(11;23)(q21;p11) in all examined metaphases.
- The karyotype was identified as 46,XX,t(11;13)(q21;p11).
- Morphological examination noted the presence of micromegakaryocytes.
Implications:
- This case expands the understanding of genetic variations in pediatric acute nonlymphocytic leukemia.
- The identified t(11;23)(q21;p11) translocation may serve as a potential diagnostic or prognostic marker.
- Further research into this specific translocation could lead to targeted therapies for leukemia.
