POSTTRANSPLANTATION LYMPHOPROLIFERATIVE DISORDER IN CARDIAC TRANSPLANT ALLOGRAFTS

Posttransplantation lymphoproliferative disorder occurs in 1.5% to 13% of heart transplant recipients and rarely involves the allograft. We report a case of posttransplantation lymphoproliferative disorder rest ricted to the mitral valve in a heart transplant recipient. Thirteen c ases of cardiac allograft involvement by posttransplantation lymphopro liferative disorder are reported in the literature. None are restricte d to the allograft. Five specify sites of cardiac involvement. Valvula r masses without infection necessitate evaluation for posttransplantat ion lymphoproliferative disorder involvement of: the cardiac allograft valve.
