Post-transplantation lymphoproliferative disorder with gastrointestinal involvement
نویسندگان
چکیده
Post-transplantation lymphoproliferative disorders (PTLDs) are lymphoid proliferations or lymphomas that are the second most common tumors in adult transplant recipients. Most cases of PTLD are attributed to Epstein-Barr virus, which induces B-cell proliferation and occurs in the setting of severe immunosuppression after solid organ or bone marrow transplantation. The disorder is seen in 1-3% of liver transplant recipients and has a variable presentation chronology. Herein, we chronicle a case of aggressive B-cell lymphoma (PTLD WHO class-3) presenting with isolated gastrointestinal involvement in an Epstein-Barr virus-negative patient with living-donor liver transplantation, 4 years after receiving the transplant. While typical symptoms may be elusive in the immunocompromised setting, clinicians should be vigilant for underlying PTLD with isolated gastrointestinal involvement. Prompt detection and characterization by endoscopic evaluation with biopsy should be particularly stressed in such patients.

Post-transplantation lymphoproliferative disorder (PTLD) is a serious complication of solid organ transplantation that occurs due to immunosuppression and other risk factors. PTLD may present with involvement of other organs and with unusual presentation. The presentation is often extranodal (e.g., in the gastrointestinal tract, lung, or the central nervous system). Herein, we report on a 1.5-y...

One well recognized and potentially serious complication of chronic immunosuppression in organ transplant recipients is post-transplantation lymphoproliferative disorders (PTLD). This accounts for 20% of all malignancies in transplant recipients, which is four times higher than the general population (1,2). The diagnosis of PTLD is often difficult, due to various manifestations resulting in lat...
