Successful treatment of primary donor-derived human herpesvirus-8 infection and hepatic Kaposi Sarcoma in an adult liver transplant recipient.

Kaposi sarcoma (KS) may rarely occur in transplant recipients through primary human herpesvirus-8 (HHV-8) infection from a seropositive donor. This report describes a patient who developed hepatic KS after receiving a split liver transplant from an HHV-8-positive donor. The recipient was treated with liposomal doxorubicin after reduction in immunosuppression led to acute cellular rejection. This treatment achieved regression of KS while preserving allograft function, demonstrating a successful therapeutic strategy for this malignancy.
