Concomitant Kaposi sarcoma and multicentric Castleman's disease in a heart transplant recipient.

Post-transplant human herpes virus -8 (HHV-8)/Kaposi sarcoma herpes virus (KSHV) infection is associated with neoplastic and non-neoplastic diseases. Kaposi sarcoma (KS), multicentric Castleman's disease (MCD), and primary effusion lymphomas (PEL) are the most common HHV-8-associated neoplastic complications described in solid organ transplant (SOT) patients. Concurrent KS and MCD have been previously described after transplantation only twice - once after liver transplantation and once after renal transplantation. We describe a unique heart transplant patient who also developed concurrent KS and MCD. To our knowledge this is the first documented case of a heart transplant recipient presenting with these two HHV-8-mediated complications at the same time.
