Posttransplant lymphoproliferative disorder presenting as a nonhealing extraction socket: a case report and review of the literature.

Posttransplant lymphoproliferative disorder (PTLD) is a well-recognized complication of long-term immunosuppression following hematopoietic or solid organ transplantation and is associated with significant morbidity and mortality. We present a unique case of PTLD that manifested with a nonhealing dental extraction socket 17 years after renal transplantation. We summarize the existing literature and present a review of an additional 25 cases. These highlight the variable clinical presentations of PTLD within the oral cavity and clear potential for delayed presentation at this anatomical subsite.
