Abstract:
Marked impairment of the cellular immune system predisposes renal transplant recipients to Epstein-Barr virus (EBV) associated clinical syndromes. This can culminate in post-transplantation lymphoproliferative disorders (PTLD) and malignant lymphomas. An unusual PTLD in a 59-year-old renal transplant recipient is reported here. Sonography and CT scan revealed a hypovascular infiltrating tumor mass in the lower pole of the graft which on histopathologic examination revealed a monotonous lymphoid proliferation. T-cell receptor and immunoglobulin heavy chain gene rearrangement as well as immunohistochemical analyses demonstrated a polyclonal origin of atypical lymphatic T- and B-cells. The Epstein-Barr viral genome was detected in the mass by Southern blot analysis, and a primary EBV infection was confirmed by serologic studies. Clinical follow-up showed a tumor-free course till the patient's sudden cardiac death 14 months after the operation.
