In agreement with previous studies, no immunophenotypic features (other than monocytic differentiation) predicted the presence of an 11q23 rearrangement. No abnormalities were detected for the other phenotypic markers analyzed, . Conclusion: Only 5 similar cases have been described previously. These abnormalities were related to immunophenotypic markers as detected using a consensual panel of monoclonal antibodies allowing lineage assignment and investigation of myeloid marker expression on blast cells. Chronic lymphocytic leukemia is an extremely heterogeneous disease and prognostic factors such as chromosomal abnormalities are important predictors of time to first treatment and survival.
