Summary
This study details a rare case of acute eosinophilic leukemia with a specific chromosomal translocation, t(10;11)(p14;q21). This genetic abnormality is associated with aggressive disease and poor response to chemotherapy.
Area of Science:
- Hematology
- Oncology
- Cytogenetics
Background:
- Acute eosinophilic leukemia (AEL) is a rare hematologic malignancy.
- Chromosomal abnormalities play a crucial role in leukemia development and prognosis.
Observation:
- A patient presented with AEL and a unique sole karyotypic abnormality: t(10;11)(p14;q21).
- Clinical features included extreme hypereosinophilia, immature eosinophils, and significant marrow, skin, and lymphoid infiltration.
Findings:
- The t(10;11)(p14;q21) translocation was the only chromosomal abnormality identified at diagnosis and relapse.
- The patient experienced only a brief remission following chemotherapy treatment.
Implications:
- This case represents the second report of the t(10;11)(p14;q21) cytogenetic/clinicopathological association in AEL.
- The recurrent finding of this translocation and poor response to chemotherapy suggests it may indicate a poor prognosis in AEL.
