title: Diffuse large B-cell lymphoma arising from donor lymphoid cells after renal and pancreatic transplantation.
abstract: A patient with both a renal and pancreatic transplantation developed a diffuse large B-cell lymphoma, Epstein-Barr virus-related, 14 months after the surgical procedure. Tumor was confined to the transplanted organs: head of the pancreas and hilar lymph node of the transplanted kidney. Chimerism analysis demonstrated the tumor origin from donor lymphoid cells. Immunosuppression was discontinued and chemotherapy with cyclophosphamide, hydroxydaunomycin, vincristine, and prednisone (CHOP) was started. However, no response was observed after three courses of this regimen. Finally, a transplantectomy was carried out, followed by rituximab (anti-CD20 antibody), with the patient achieving a complete response (CR). Two years later the patient remains in CR.
