Abstract
Human herpesvirus-8 (HHV-8) remains best known as an oncogenic virus, but nonneoplastic disease manifestations, such as bone marrow failure or hemophagocytic lymphohistiocytosis (HLH) have gained greater recognition in recent years. In organ transplantation, HHV-8 infection commonly occurs with reactivation of latent virus among recipients from endemic regions of the world or due to transmission from the organ donor. We describe a case of HHV-8-associated HLH in a liver transplant recipient at increased risk for primary infection. Our case highlights the risk of non-donor-derived, posttransplant primary HHV-8 infection, and demonstrates that HLH can be a life-threatening complication of this infection.
