Detection of Epstein-Barr virus in posttransplantation T cell lymphoma in a kidney transplant recipient: case report and review.
Posttransplantation T cell lymphomas (PTTLs) are rather unusual, and their etiology remains unclear. We describe a case of Epstein-Barr virus (EBV)-associated small bowel T cell lymphoma in a patient 5 years after kidney transplantation. EBV was detected in a biopsy sample by in situ hybridization, immunohistochemical staining, and polymerase chain reaction analysis. Eight previously reported cases of EBV-associated PTTL are reviewed, in which special attention is paid to the methods used for assessing EBV. This case of EBV-associated PTTL is believed to be the most completely studied from the point of view of the methods used for detection of EBV. The prognosis of PTTL is poor, but it has been reported that therapeutic approaches can be successful if they are given early in the course of the illness. Therefore, it is necessary to improve the diagnosis PTTL and to assess the precise involvement of EBV in posttransplantation lymphoproliferative disorders.
