Follicular lymphoma following liver transplantation: report of a unique case with review of the literature.

Lymphoproliferative disorders following organ transplantation are often Epstein-Barr virus-related high-grade B-cell lymphoid proliferations. Posttransplant low-grade lymphoproliferative disorders are uncommon. We report a low-grade follicular lymphoma with typical follicle center cell immunophenotype and t(14;18) translocation involving the major breakpoint region in a liver recipient.
