Epstein-Barr Virus-negative posttransplant lymphoproliferative disorder with coexisting native renal cell carcinoma: PET/CT demonstration.

Compared with the general population, solid organ transplant recipients, including renal transplant patients, who are under long-term immunosuppression, present with up to a 120-fold increased risk of developing skin cancer and non-Hodgkin lymphoma. For the renal transplant population with prior long-term dialysis, there is also an enhanced potentiality of native kidney malignancy. The authors present a case with a posttransplant lymphoproliferative disorder of the duodenum and concomitant left native papillary renal cell carcinoma. The uncommon coexistence of these 2 malignant processes is demonstrated by PET/CT imaging.
