Interphase fluorescence in-situ hybridization (FISH) was performed with a panel of probes including myc, bcl-2/IgH and bcl-6 to document related gene translocation and copy number changes.     ///    "Among 145 cases, 5 cases (3.4%) of B cell lymphomas with concurrent myc and bcl-2/IgH or bcl-6 rearrangements (double-hit lymphomas) were identified, including 2 cases involving myc and bcl-2 translocations (1 DLBCL and 1 BCLU), and 3 cases involving myc and bcl-6 translocations (all DLBCLs). "    ///    " To identify and investigate clinicopathological features of B cell lymphomas with concurrent myc and bcl-2/IgH or bcl-6 translocations (""double-hit"" lymphoma).
