Epstein-Barr virus-associated peripheral T-cell lymphoma and hemophagocytic syndrome arising after liver transplantation: case report and review of the literature.

Post-transplantation lymphoproliferative disorders (PTLD) are a well-recognized complication of solid organ transplantation. The vast majority of PTLD are Epstein-Barr virus (EBV)-related infections that manifest as B-cell malignancies. We report an unusual case of an EBV-associated T-cell lymphoma in a 10-year-old boy who had previously undergone liver transplantation at age 4 years. He presented with hemophagocytic syndrome (HPS) and active EBV infection, with positive serum titers and polymerase chain reaction (PCR) for EBV in blood, colon, and antral samples.
