ABSTRACT: Here, we report the case of a 57-year-old man, who was diagnosed with B-cell acute lymphoblastic leukemia (B-ALL). His diagnostic workup identified a translocation t(3;9)(p13;p13). This is the fifth case reported to date that involved the forkhead box P1 gene (FOXP1) and paired box gene 5 (PAX5). The PAX5-FOXP1 translocation is a nonrandom aberration, which is recurrent in both childhood and in adult B-ALL, and may contribute to leukemogenesis by blocking differentiation of hematopoietic cells into mature B-cells.
