Autoimmune Phenomenon Associated With Posttransplant Lymphoproliferative Disorder

Post-transplant lymphoproliferative disorders (PTLDs) encompass heterogeneous lymphoid or plasmacytic proliferations occurring in immunocompromised patients following both solid organ and hematopoietic stem cells transplantation.1 Among them, T- and NK-cell monomorphic PTLDs are rare entities, representing 2-15% of all PTLD that fulfil the criteria for any of the T- or NK-cell lymphomas.2
