Organ transplantation carries a risk of disease transmission from donor to recipient, primarily infection or malignancy. Although donors are thoroughly screened, donor-related malignancies are reported to occur in 0.01% of solid organ transplants. Plasma cell neoplasm, to the best of our knowledge, has not been reported as a donor-transmitted malignancy in liver transplantation. We describe a liver transplant from a donor with unrecognized plasmacytoma requiring retransplantation. Three years after the first transplant a single peritoneal mass was detected on surveillance imaging and radically excised; HLA phenotyping confirmed the mass to be an isolated extra-medullary plasmacytoma of chimeric donor and recipient origin.
Keywords: Donor-related malignancy; liver transplant; plasmacytoma; posttransplant lymphoproliferative disorder.
