Using molecular techniques to confirm donor-derived post-transplant lymphoproliferative disorder
June 2014—Post-transplantation lymphoprolif-erative disorders (PTLD) encompass a spectrum of neoplasms, ranging from benign hyperplasia to non-Hodgkin lymphoma and Hodgkin lymphoma. Epstein-Barr virus is postulated to play a key role in the pathogenesis of PTLD in patients who were previously EBV negative. This is a case report of a 52-year-old female, status post unrelated bone marrow transplant for myelofibrosis, who developed primary central nervous system diffuse large B-cell lymphoma, post-transplantation.
