Rapidly progressive post-transplant lymphoproliferative disease following withdrawal of sirolimus.

ABSTRACT

Sirolimus, a potent inhibitor of B- and T-cell activation. is a commonly used immunosuppressant after renal transplantation. Withdrawal of sirolimus from the immunosuppression regimen may reduce B-cell surveillance. We present a case of rapidly progressive central nervous system (CNS) polymorphic Epstein-Barr virus (EBV)-related post-transplant lymphoproliferative disorder following the withdrawal of sirolimus.
