Posttransplant Lymphoproliferative Disease(PTLD) following Renal Transplantation / 대한이식학회지

ABSTRACT

Posttransplant lymphoproliferative disease(PTLD) represents a diverse lymphoproliferative disorder ranging from non-specific reactive hyperplasia to malignant immunoblastic sarcoma developed in a setting of immunosuppression following organ or cellular transplantation. It is often associated with Epstein-Barr virus infection and high dose immunosuppression. EBV detection and immunotyping including immunoglobulin clonality is crucial for prediction of prognosis and treatment modality. We report one case of PTLD developed 5 months after renal transplantation in 33 year-old man. Clinical manifestion was submandibular mass, and EBV was detected by in situ hybridization. Histology and immunotyping revealed immunoblastic lymphoma andl lambda chain monoclonality. He has been treated with reduction of immunosuppression, acyclovir and radiotherapy, and is in stable condition with normal renal function at postoperative 11months without evidence of disease reccurrence.
