Posttransplant lymphoproliferative disorders (PTLDs) are potentially fatal complications arising after solid organ or hematopoietic stem cell transplant. The most crucial factor in pathogenesis of PTLDs is either a primary infection with Epstein–Barr virus or reactivation of its latent state due to immune dysregulation. This complex pathobiology leads to a myriad of clinical manifestations due to uncontrolled lymphoproliferation that may be reactive, polymorphous or monomorphous. We report our experience at a tertiary center of six cases detected over a span of six years. All our patients were proven as high grade B-cell lymphoma on histopathology, which remains the gold standard for diagnosis. Two cases were of primary central nervous system lymphoma, two had disseminated disease, fifth showed allograft involvement, and last case presented with gastrointestinal obstruction. All the patients were managed with reduction of immunosuppression, chemotherapeutic agents, and rituximab. Five patients responded well with a follow-up period of 3–28 months since the time of treatment initiation and had preserved renal function with no episodes of disease recurrence or allograft rejection.
