    We present a patient with chemotherapy-refractory Chronic Lymphocytic
    Leukemia (CLL) in whom postmortem examination showed hepatosplenomegaly,
    with both multiple small-cellular CLL lesions and large-cellular, monoclonal
    T-cell infiltrates. Following this case, the co-incidence of T-cell malignancies and
    CLL was studied using Dutch and American cancer registry databases. Analysis
    showed an excess risk for T-cell malignancies in CLL patients, with increased
    standardized incidence ratios compared with the general population and all
    cancer survivors in the databases. We hypothesize that CLL cells interact with
    T-cells in the microenvironment, facilitating malignant transformation
