Posttransplant Iymphoproliferativedisorders (PTLD)are primarilyB lymphocyte tumors which are related to the Epstein-Barr virus. Recent studies have more clearly delineated neoplastic from hyperplastic forms of this disease. Factors associated with increased PTLD risk include recipient EBVseronegative status and heavy immunosuppression. The clinical presentation of PTLD is reviewed and lesser known features such as respiratory compromise or localization of tumors to skin are highlighted. The pathologic classifications of PTLD are surveyed and related to one another. Newer approaches to therapy, including the use of monoclonal antibodies and adoptive cellular immunotherapy, are discussed.
