We report on a case of a 30-year-old male with acute B-lymphoblastic leukemia (B-ALL) with immunophenotype CD19(+), CD22(+), CD20(+), CD10(+), with aberrant expression of CD13 and CD117, and IgH gene rearrangements.
Additionally, investigators have associated expression of CD13 and CD11b by chronic B-cell lymphoid leukemias with a more aggressive clinical course and shorter survival.
