[Lymphoproliferative disease in pediatric liver transplantation]

Post-Transplant Lymphoproliferative Disorders are due to continuous B-lymphocyte proliferation induced by Epstein-Barr Virus (EBV) infection which is recovered in 88% of transplanted patients. These disorders may present clinically as lymphadenopathic syndrome with lymphoid tissue hyperplasia, systemic as a mononucleosis-like syndrome and lymphomatous syndrome, indistinguishable from non-Hodgkin's lymphoma. We present 10 patients of PTLD classified as 7 lymphadenopathic, 1 systemic (this patient had both syndromes) and 3 lymphomatous tumours. At present, PTLD treatment consists of surgical removal of accessible masses or post-chemotherapy (ChT) tumour rests, total or partial withdrawal of immunosuppressive drugs and ChT following the Sociéte Française d'Oncologie Pédiatrique (SFOP) protocol for non-Hodgkin's lymphoma.
