Translocation (14;14)(q11;q32) is one of the recurrent chromosome aberrations in ataxia-teleangiectasia (AT) and T-cell malignancies. In patients with the t(14;14), the TCL1 and TCRalpha/delta genes were found to be involved at the molecular level. However, t(14;14)(q11;q32) is an exceedingly rare phenomenon in B-lineage acute lymphoblastic leukemia (B-ALL). To date, it has been reported in only 5 B-ALL cases. Here, we report another B-ALL case with t(14;14)(q11;q32) in a 39-year-old female. The immunophenotype of the blasts showed positivity for CD79a, CD10, CD19, and HLA-DR. Chromosome analysis of the bone marrow (BM) cells at presentation showed the karyotype 47,XX,+4,t(14;14)(q11;q32). Fluorescence in situ hybridization (FISH) demonstrated trisomy 4 and the simultaneous involvement of the IGH gene at 14q32 and the CEBPE gene at 14q11, which differs from the genes involved in T-cell leukemias. After chemotherapy, the patient achieved complete remission (CR). Later, she received allogeneic peripheral blood stem cell transplantation. After CR, the karyotype of the BM cells was normal. She was disease-free at a 6-month follow-up. We suggest that t(14;14)(q11;q32) involving the IGH and CEBPE genes in B-ALL is rare, but it is a recurrent abnormality that could identify a new subgroup of B-ALL.
