PTLDs comprise a spectrum ranging from early, Epstein-Barr virus (EBV)-driven polyclonal lymphoid proliferations to EBV-positive or EBV- negative lymphomas of predominantly B-cell or less often T-cell type. (WHO, 2001) Post-Transplant Lymphoproliferative Disorder GDC Post-Transplant_Lymphoproliferative_Disorder Abnormal proliferation of B lymphocytes as a complication of immunosuppression occurring after solid organ or allogenic stem cell transplantation.

This usually happens if the patient has also been infected with Epstein-Barr virus. Post-transplant lymphoproliferative disorder may progress to non-Hodgkin lymphoma.
