A Rare Case of Classical Hodgkin Lymphoma Diagnosed 10 Years after Liver Transplant

Abstract

Posttransplant lymphoproliferative disorders (PTLD) represent a rare and potentially life-threatening complication after liver transplantation. Classical Hodgkin lymphoma (cHL), with an incidence of approximately 1.8–3.4% of all PTLD cases, represents a minority of PTLD, mainly presenting as a late transplant complication. The main risk factors for the development of PTLD are Epstein-Barr virus (EBV) infection and intensive immunosuppression. However, other risk factors like hepatitis C virus may, together with EBV infection, contribute to the development of PTLD. Here we present a case of late-onset EBV-positive cHL that occurred 10 years after an unrelated donor liver transplantation. To our knowledge, this is the first report of cHL occurring with such a long interval after liver transplantation. Given the low incidence of cHL PTLD, there is little information regarding pathology, clinical characteristics, and management of this disease. The development of individual, risk-adapted treatments may improve the long-term outcome of cHL PTLD.
