BCL6 and Burkitt lymphoma: Features that favour Burkitt’s lymphoma include morphology, an immunophenotype that is CD20+, CD10+, Bcl-6+, Bcl-2−, TdT−, and monotypic sIg+, with virtually all cells Ki67+ (proliferation), and a translocation involving c-Myc and IgH or IgL, without rearrangements involving the bcl-2 or bcl-6 genes [49].
