Abstract
Post-transplant lymphoproliferative disorder (PTLD) is one of the most common malignancies affecting solid organ transplant recipients. The disease is frequently associated with Epstein-Barr virus (EBV) infection (70% of cases) and cases are often delineated by EBV positivity status. The oncogenesis of EBV-positive PTLD is well-described in the literature; however, the etiology of the EBV-negative subtype is poorly understood. This report describes a case of EBV-negative PTLD developing in a combined kidney-pancreas transplant recipient with an incidental finding of untreated chronic hepatitis C virus (HCV). Our experience suggests an association between HCV and EBV-negative PTLD. Additional well-designed studies are needed to further investigate this association.
