Lymphoproliferative disorder in a twin female teenager post kidney transplantation.

Post-transplant lymphoproliferative disorder (PTLD) is defined as a heterogeneous group of lymphoid and plasmocytic proliferations with variable malignant potential. They often arise in immunocompromised post solid organ transplant (SOT) patients linked with Epstein-Barr virus (EBV) infection. Clinical manifestations include fever, lymphadenopathy and organ involvement. Diagnosis of PTLD requires morphopathological tissue examination. Treatment of EBV-related PTLD in SOT patients includes immunosuppressive (IS) agents' reduction, use of antiviral medication, anti-B-lymphocyte antibodies and chemotherapy for high-risk patients. We report a case of late EBV-related PTLD occurring in a young female, coming from twins, nine years after renal transplant from deceased donor. Both sisters were diagnosed at the age of 10 with chronic kidney disease (CKD) based on nephronophthisis and underwent the first simultaneous renal transplant from deceased donor in Romania. PTLD Hodgkin's-like lymphoma and EBV-positive lesions were to be found in autopsy. Routine EBV viral load testing and immune condition in SOT patients could identify PTLD risk factors therefore early treatment can be applied. Monitoring EBV serology and immunological parameters are preferred as strategy for PTLD prevention.
