A 50-year-old woman developed a subcutaneous tumor in the left lower leg. A biopsy led to the diagnosis of lymphoid malignancy. The malignant cells showed a B-cell immunophenotype. Karyotyping of the cells revealed t(14;18) and t(2;3). The patient was treated with chemotherapy, resulting in a transient response. Subsequently, tumor regrowth and bone marrow recurrence developed. Karyotyping of the bone marrow at relapse revealed a t(8;22) in addition to t(14;18) and t(2;3), which led to a diagnosis of acute lymphoblastic leukemia (ALL)-L3 (FAB). Although the patient was treated with several chemotherapy regimens, the disease was refractory to all the treatments. Fluorescence in situ hybridization (FISH) and the nested polymerase chain reaction (PCR) technique demonstrated rearrangements of the c-myc, bcl-2, and bcl-6 genes. ALL-L3 associated with t(14;18) is known to be complicated frequently with cerebrospinal infiltration and extramedullary lesions, and has a poor prognosis. In our case, the presence of the additional t(2;3) may have enhanced this patient's refractoriness to the treatment.
