Abstract: Post-transplant lymphoproliferative disease (PTLD) is a well-known late complication of organ transplantation which incidence has
increased after the introduction of more powerful immunosuppressive agents. A 58-year-old man performed ABO-incompatible living kidney
transplantation in June, 2008. At 3 years and 9 months after the transplantation, the patient complained of general fatigue and dyspnea and
was hospitalized with renal dysfunction. The clinical data in hospital showed acute rejection, but soluble IL-II exceeded 21700U/ml, and HE
staining kidney graft showed a massive infiltration of atypical lymphocytes. Atypical lymphocytes were positive for L-26 and negative for CD3
immunochemical stein, and the EBER in situ hybridization stain for EBV was negative in renal graft. We diagnosed diffuse large B-cell
lymphoma in the kidney graft. However, he died due to multiple organ failure (MOF). We described a fatal case of diffuse large B-cell lymphoma
without EBV infection occurring 3 years 9 months after ABO-incompatible kidney transplantation. Unfortunately, his biopsy after his death using
EBER-ISH stain showed whether EB virus infection was a cause.
