A case of an Epstein-Barr virus (EBV)-associated B lymphoproliferative disorder presented as a renal transplant obstruction is reported. The diagnosis was made from histology, immunohistochemistry, and EBV expression studies. Cytogenetic analysis showed the tumor to be of donor origin and revealed chromosomal translocation 46, XY, inv (1)(p35; q41), involving the EBV insertion site 1(1p35) and transforming growth factor beta 2(1q41) loci. |
