Soft Palate Ulcer: An Unusual Presentation of a Posttransplant Lymphoproliferative Disorder

Roles of F-18-Fluoro-2-Deoxy-Glucose PET/Computed Tomography Scans in the Management of Post-Transplant Lymphoproliferative Disease in Pediatric Patient

Post-transplant lymphoproliferative disease is a well-known complication in transplant recipients. Evaluating the extent and stage of disease is important for management and follow-up. As a combination of anatomic and functional imaging, PET/CT is a sensitive and specific tool to stage and detect occult disease compared with conventional imaging. PET/CT also has a role in monitoring treatment response. Although PET/CT has been shown to be potentially useful in adults, evidence in children is insufficient. This review provides an overview of the use of PET/CT in post-transplant lymphoproliferative disease, especially in pediatric patients.

Recurrent oral ulcerations following heart transplant in a pediatric patient: A diagnostic dilemma

Oral ulceration is a non-specific clinical finding with many potential causes. The persistence of oral ulcers in the context of a patient post-SOT is concerning for PTLD. There is growing evidence that SOT recipients may also be at higher risk of autoimmune diseases. This case report describes a pediatric patient with persistent oral ulcers after heart transplant, who underwent an extensive workup for PTLD, including repeat investigations, with a subsequent diagnosis of Behçet's disease.
