Abbreviations: BL, Burkitt’s lymphoma; LNCCL, large noncleaved cell lymphoma; IBL, immunoblastic lymphoma; PCNSL, primary central nervous system lymphoma.

Minor phenotypic patterns included: BCL6/MUM1/syn1 in one systemic NHL (with LNCCL morphology) that scored negative for p27Kip1; BCL6/MUM1/syn1+ in one PCNSL (with IBL morphology) that scored negative for p27Kip1; BCL6+/MUM1+/syn1+ in two PCNSL (with LNCCL/IBL morphology) one of which scored positive for p27Kip1; and BCL6+/MUM1/syn1+ in one PCNSL (with LNCCL/IBL morphology) that scored negative for p27Kip1.
