Monomorphic Epstein-Barr virus (EBV)-associated large B-cell posttransplant lymphoproliferative disorder presenting as a tongue ulcer in a pancreatic transplant patient.

Posttransplant lymphoproliferative disorders are a group of lymphoid proliferations and lymphomas that develop as a consequence of immunosuppression in recipients of solid organ or bone marrow allografts. We describe an unusual oral presentation of posttransplant Epstein-Barr virus-associated diffuse large B-cell lymphoma in a 45-year-old woman after pancreatic transplant.
