NCIt definition : Post-transplant lymphoproliferative disorder (PTLD) is a polyclonal (benign) or clonal
(malignant) proliferation of lymphoid cells that develops as a consequence of immunosuppression
in a recipient of a solid organ or bone marrow allograft. 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);
Alternative definition : NCI-GLOSS: A condition in which a group of B-cells grow out of control after an organ
transplant in patients with weakened immune systems. This usually happens if the patient
has also been infected with Epstein-Barr virus. Post-transplant lymphoproliferative
disorder may progress to non-Hodgkin lymphoma.; NICHD: Abnormal proliferation of B lymphocytes as a complication of immunosuppression
occurring after solid organ or allogenic stem cell transplantation.;
