Purpose: To describe a patient with conjunctival posttransplantation lymphoproliferative disorder (PTLD).
Design: Interventional case report.
Methods: A 8-year-old boy, three months status post bone marrow transplantation with bilateral enlarged gelatinous bulbar conjunctiva was examined. Biopsy of the bulbar conjunctiva was performed.
Results: Conjunctival biopsy revealed a polymorphous infiltrate of lymphoid cells with large atypical immunoblastic lymphoma cells, plasmacytoid lymphocytes, and plasma cells. B-cell markers CD20 and CD79a were positive. Plasma cells exhibited restriction for kappa immunoglobulin light chain and were positive for CD79a. Most cells were positive for Epstein-Barr virus (EBV) encoded ribonucleic acid. EBV-related polymorphic PTLD was diagnosed and treated with discontinuation of cyclosporine, reduction in prednisone dosage and administration of EBV-specific cytotoxic T lymphocytes. The conjunctival lesions resolved during the next five weeks.
Conclusions: Posttransplantation lymphoproliferative disorder rarely involves the ocular structures with most cases presenting as a masquerade syndrome. This case illustrates that PTLD can involve the conjunctiva and further expands the clinical spectrum of ocular PTLD.

Post-transplant lymphoproliferative disorders (PTLD) are complications that arise from post-transplantation immunosuppressive therapy. Although Epstein-Barr virus (EBV) viremia is often seen in PTLD, it is not a definitive feature for diagnosis. We report a rare case of recurrent PTLD in a 26-year-old heart transplant recipient on high-dose tacrolimus who presented with emesis, fatigue, and bloody diarrhea.

Article Synopsis
- Letermovir (LTV) prophylaxis significantly reduces the incidence of clinically significant cytomegalovirus (CMV) infection after allogeneic hematopoietic stem cell transplantation (allo-HSCT).
- A study of 230 patients показал that those receiving LTV experienced a higher rate of Epstein-Barr virus (EBV) reactivation (27%) compared to those who did not receive LTV (13%).
- Despite the increased EBV reactivation, there were no major differences in recovery metrics, overall survival, or other complications between the LTV and control groups, suggesting a possible link between LTV use and increased EBV reactivation post-transplant.
Prevention of post-transplant lymphoproliferative disorder in pediatric kidney transplant recipients.

Article Synopsis
- Post-transplant lymphoproliferative disorder (PTLD) often occurs in patients who have undergone organ or stem cell transplants and is linked to Epstein-Barr virus (EBV) infection, which precedes PTLD in 90% of cases.
- A study involved pediatric kidney transplant recipients (PKTR) who were monitored for EBV through blood tests, and those with rising viral loads despite lowering immunosuppressive drugs were given preventive rituximab therapy.
- Results showed that rituximab was effective in clearing EBV from patients who struggled to respond to other treatments, suggesting that it may be a safe option for preventing PTLD in high-risk pediatric kidney transplant patients.

Purpose Of Review: Viral infections are important complications after allogeneic hematopoietic stem cell transplantation. New infections develop such as SARS-CoV-2 with the potential for severe consequences. In this review, newly published information regarding management of viral infections is discussed.

Chronic rejection (CR) is a progressive immunological injury that frequently leads to long-term liver allograft dysfunction and loss. Although CR remains an important indication for retransplantation, as transplant immunosuppression has evolved, its prevalence in adults undergoing liver transplantation (LT) has declined. However, the incidence and factors that lead to CR in pediatric LT are poorly defined.
