Renal Transplant Obstruction by B Cell Lymphoproliferative Disorder: Case Report and Review of the Literature

Abstract
We report a case of renal transplant ureteral obstruction caused by a cyclosporine-assocaited B cell lymhoproliferative disorder. The interaction of cyclosporine with Epstein-Barr virus infections and the predisposition towards B cell lymphoproliferative disorders are reviewed. The characterization of these tumors by deoxyribonucleic acid hybridization studies and a review of the clinical experience treating these disorders are also presented.
