Lymphoproliferative disorder presenting as a tumor of the renal allograft

Post-transplant lymphoproliferative diseases (PTLDs) constitute a group of potentially life-threatening complications in solid organ transplantation, occurring in 1-2% of kidney transplant recipients. The absolute number of cases occurring at each transplant center remains small, making it difficult to assess incidence, prognosis, and treatment. We report a case of post-transplant lymphoproliferative disorder that developed in the allograft renal parenchyma 2 years after renal transplantation. This case implies that partial nephrectomy may be a safe and effective treatment protocol for renal lymphoma in allograft kidneys.
