Posttransplant lymphoproliferative disorders [PTLD] are lymphoid proliferations that develop in solid organ or allogeneic bone marrow transplant recipients. PTLD represents a spectrum, ranging from an EBV-driven polyclonal hyperplasia in an infectious mononucleosis-like picture to malignant B- and T-cell lymphomas indistinguishable from their counterpart in immunocompetent individuals. Cutaneous PTLD is rare, with only around 100 cases reported in the literature.


Cutaneous lesions may present as a violaceous papule or nodule with an erythematous border.
