An acquired Robertsonian 13;15 translocation in acute myelogenous leukemia (M5b).

A 43-year-old male developed acute myelogenous leukemia (AML, M5b) with an acquired Robertsonian 13;15 translocation. He did not achieve complete remission after sequential intensive induction chemotherapy and he died 13 months later. We reviewed 7 patients with this translocation reported in the literature. Acquired Robertsonian translocations are rare, but could represent an important event in the tumorigenesis of hematologic malignancies.
