Clinics and Pathology


B-cell acute lymphoblastic leukemia (ALL) with hypereosinophilia

Phenotype stem cell origin

CD19+, CD10+ ALL; eosinophils are not part of the leukemic cells and do not carry the t(5;14); they represent a reactive population (eosinophilia in association with ALL is usually reactive)


rarely described; 6M/1F; affects both children and adults, general features of ALL with hypereosinophilia are rarity, male predominance; and young age


marked eosinophilia; basophilia; IL3 is over-expressed


prognosis appears to be poor, a feature of ALLs with hypereosinophilia

Genes Involved and Proteins

Gene name
IL3 (interleukin-3)
Protein description
152 amino acids; growth factor; colony stimulating factor involved in the survival, proliferation and differentiation of multipotent hematopoietic cells
Gene name
IGH (Immunoglobulin Heavy)

Result of the Chromosomal Anomaly


break in the promoter region of IL3 and in the Jh region of IgH

Expression localisation

the immunoglobulin gene promoter controls the expression of IL3


over-expression of IL3
