Post-transplant lymphoproliferative disorders (PTLDs) are lymphoid or plasmacytic proliferations that develop as a consequence of immunosuppression in a recipient of a solid organ, bone marrow or stem cell allograft. The development of PTLDs is usually associated with Epstein-Barr virus (EBV) and the disorder is also termed EBV-associated lymphoproliferative disorder (LPD). The development of PTLD is a rare complication in autologous bone marrow/peripheral blood stem cell transplantation. In the present study, we report a case of EBV-associated LPD which developed following autologous peripheral blood stem cell transplantation for relapsing Hodgkin's lymphoma. A 51-year-old male presented with swelling of the left cervical lymph nodes. A biopsy revealed nodular sclerosis classical Hodgkin's lymphoma. Following four courses of ABVd (adriamycin, bleomycin, vinblastine, dacarbazine) therapy, the Hodgkin's lymphoma relapsed. CHASE (cyclophosphamide, etoposide, cytarabine, dexamethasone) therapy and autologous peripheral blood stem cell transplantation were performed. In the 128 days following the transplantation, lymph node swelling was noted and a biopsy specimen demonstrated EBV-associated LPD. The serum copy number of EBV-DNA was 2.7×10(3) copies/ml. The occurrence of EBV-associated LPD may be on the rise due to the increased number of patients undergoing immunosuppression therapy. The measurement of the serum EBV-DNA copy number and the detection of EBV-infected atypical lymphocytes using in situ hybridization are significant in establishing an early accurate diagnosis and initiating the correct treatment for EBV-associated LPD in patients with immunosuppression.
