Posttransplant lymphoproliferative disorders not associated with Epstein-Barr virus: a distinct entity?

Abstract

EBV-negative PTLD may be a late serious complication of organ transplantation. Half the tumors observed after kidney transplantation in our center were not associated with EBV and emerged after more than 5 years, which suggests the number of EBV-negative PTLDs in organ recipients might increase with time.
