title: Hodgkin lymphoma-like posttransplantation lymphoproliferative disorder.
abstract: Posttransplantation lymphoproliferative disorders (PTLD) are a heterogeneous group of monoclonal or polyclonal lymphoproliferative lesions that occur in immunosuppressed recipients following solid organ or bone marrow transplantation, including 4 categories: (1) early lesions (reactive plasmacytic hyperplasia, and infectious-mononucleosis-like PTLD), (2) polymorphic PTLD, (3) monomorphic PTLD (including B-cell neoplasms and T-cell neoplasms), and (4) Hodgkin lymphoma (HL) and HL-like PTLD in the current World Health Organization classification. Although HL-like PTLD has been grouped with classic HL PTLD, controversy remains as to whether it is truly a form of HL or whether it should be more appropriately considered as a form of B-cell PTLD. The current available literature data indicate the presence of important immunophenotypic, molecular genetic, and clinical differences between HL PTLD and HL-like PTLD, suggesting that HL-like PTLD is in fact most often a form of B-cell PTLD. Distinction from true HL may be important for clinical management and prognosis.
