Posttransplant lymphoproliferative disorders (PTLDs) are a group of diseases that range from benign polyclonal to malignant monoclonal lymphoid proliferations. They arise secondary to treatment with immunosuppressive drugs given to prevent transplant rejection. Three main pathologic subsets/stages of evolution are recognised: early, polymorphic, and monomorphic lesions. The pathogenesis of PTLD...

Posttransplant lymphoproliferative diseases are complications that develop after solid organ transplantation. Primary EBV infection is one of the most important risk factors. After deceased kidney transplantation, we presented a young male patient diagnosed with diffuse large B-cell lymphoma.

Posttransplant lymphoproliferative disorder is a serious complication following solid organ as well as hematopoietic stem cell transplantation due to prolonged immunosuppressive therapy. Plasmablastic lymphoma, although classically associated with HIV infection, has since been described in transplant patients as a variant of posttransplant lymphoproliferative disorder with varying clinical pres...

Chronic myelocytic leukemia (CML) may display a lymphoproliferative phase (lymphoid blast crisis) that is generally of B cell phenotype. Since lymphoproliferative disorders may occur following bone marrow transplantation (BMT), it may be difficult to distinguish posttransplant relapse of CML lymphoid blast crisis from de novo lymphoproliferation. Lymphoid blast crisis cells from a patient with ...

Posttransplant lymphoproliferative disease (PTLD) is a potentially life-threatening complication of hematopoietic cell transplantation. With improvements in Epstein-Barr virus (EBV) monitoring and supportive care, PTLD incidence has decreased throughout the history bone marrow It rare to develop after first year following transplant, across all donor categories. In this case, we hope elucidate ...

BACKGROUND Cutaneous T-cell lymphoma occurring in the context of posttransplant immunosuppression is rare, with 27 cases documented to date. OBSERVATIONS We report 2 new cases of posttransplant cutaneous T-cell lymphoma in patients treated at our institution. Both were male recipients of renal transplants who had undergone transplantation a mean of 5.3 years previously and were taking various...
