Acute myeloid leukemia (AML) that occurs concurrent with a diagnosis of chronic lymphocytic leukemia (CLL) is rare, but the number of cases recognized has recently dramatically increased as a result of the application of flow cytometry. This raises a series of questions regarding the clinical characterization of mixed leukemia, whether this diagnosis possesses unique cytogenetic abnormalities, and the possible association between AML and CLL cell clones. The current study attempts to answer these questions by evaluating an 80-year-old man with concurrent diagnoses of AML-M0 and CLL. Routine G-banded chromosome, array based comparative genomic hybridization, and fluorescence in situ hybridization analyses were used to characterize complex chromosomal rearrangements in the patient's bone marrow. Novel complex translocations involving chromosomes 2, 5, and 11, as well as submicroscopic deletions and duplications, were revealed. This case study reports a t(2;5;11) in either AML-M0 or in CLL by using array based comparative genomic hybridization and fluorescence in situ hybridization analyses to facilitate the diagnosis. The study also delineates the clinical characteristics and cytogenetic changes that occur with concurrent AML and CLL.
