Kim, Shim, Jang, Lee, Huh, Kim, and Lee: Posttransplant Lymphoproliferative Disorder without Epstein-Barr Virus Presented as Small Bowel Perforation in Renal Transplant Recipient: A Case Report

Abstract

Posttransplant lymphoproliferative disorder (PTLD) is documented as one of the serious complications leading to mortality particularly in organ transplant recipients receiving immunosuppressive therapy. Extant literature confirms beyond doubt that the most common site of involvement of PTLD is lymph nodes, and rarely involved is the gastrointestinal tract. It is a well-known fact that Epstein-Barr virus (EBV) is a risk factor for PTLD development. In this study, we report a case of PTLD presented as small bowel perforation without EBV infection after long-term immunosuppressive therapy in a renal transplant recipient.

Right lung showed the posttuberculosis sequelae with fibrosis and ate-lectasis combined with pleural ef-fusion. In CT scan showed the in-traperitoneal free air (arrows), and the focus of perforation was not defined.
