Post-transplant lymphoproliferative disorders (PTLD) are lymphoid or plasmacytic proliferations that develop as a consequence of immunosuppression in a recipient of a solid organ, bone marrow, or stem cell allograft. The early lesions are defined as lymphoid proliferations in an allograft recipient, characterized by architectual preservation of the involved tissue, with preservation of the nodular sinuses or tonsillar crypts, and residual or sometimes floridly reactive follicles in some cases.
