Posttransplant lymphoproliferative disorder (PTLD) is a serious complication of solid organ transplantation. It has several clinical manifestations, including infectious mononucleosis-like syndrome, lymphadenopathy, and other organ involvement. Soft palate ulcer is a rare manifestation of PTLD. The aim of this study is to present a 17-year-old girl with liver transplantation due to metastatic liver disease. After transplantation, she presented with a painful whitish ulcerative lesion accompanied by central necrosis in the right soft palate area measuring about 3 cm×3...

PURPOSE OF REVIEW: Post-transplant lymphoproliferative disease (PTLD) is a major complication of hematopoietic stem cell and solid organ transplantation. The incidence of transplantation in childhood has been steadily rising, making PTLD the most common form of lymphoproliferation in childhood. The purpose of this review is to summarize the role of the Epstein-Barr virus (EBV) in the pathophysiology and discuss the management of PTLD. RECENT FINDINGS: More than 90% of pediatric PTLD is EBV-positive...

Post-transplant lymphoproliferative disorder (PTLD) is associated with a variety of clinical presentations, but rarely involves the skin. We herein report a case of PTLD presenting with skin ulceration in a renal transplant recipient. A biopsy of the ulcer confirmed the diagnosis of diffuse large B-cell lymphoma. The patient was initially treated with immunosuppression reduction, but the skin ulcer persisted. He was then treated with two courses of chemotherapy, but his condition was complicated with cryptococcal infection...

INTRODUCTION: Post-transplant lymphoproliferative disease (PTLD) comprises a variety of lymphoid and plasma cell disorders arising in patients with a solid organ transplant. Monomorphic lymphomas represent the most significant part of this wide spectrum, with the overall risk rising with the aggressiveness of lymphoid proliferation in comparison to the general population. The development of Hodgkin lymphoma is very rare in transplant recipients, comprising less than 6% of all monomorphic PTLD, while cases of primary intestinal Hodgkin lymphoma in these circumstances are anecdotal...

BACKGROUND: Induction treatment with rabbit polyclonal antithymocyte globulins (ATGs) is frequent used in kidney transplant recipients with donorspecific HLA antibodies and shows acceptable outcomes. The two commonly used ATGs, Thymoglobulin and ATG-F have slightly different antigen profile and antibody concentrations. The two compounds have never been directly compared in a prospective trial in immunological high-risk recipients. Therefore we performed a prospective randomized controlled study comparing the two compounds in immunological high-risk kidney recipients in terms of safety and efficacy...

AIMS: To examine the need for minimal diagnostic criteria for post-transplant lymphoproliferative disorders (PTLD) in children, we sought to determine the rate of incidental Epstein-Barr virus (EBV)-positivity in tissues from organ transplant recipients (OTR). METHODS: EBV in situ hybridisation (ISH) was done retrospectively on tissue from 34 paediatric autopsies of OTR and paediatric tonsillectomy specimens from non-OTR (96) and OTR (6). Patients with a history of PTLD were excluded from both data sets...

Post-transplant lymphoproliferative disorder (PTLD) is a life-threatening complication of solid organ transplantation. We herein report a case of PTLD after living-donor liver re-transplantation (reLDLT) for recurrent primary sclerosing cholangitis (PSC), for which complete response was achieved by surgical resection and rituximab. A 47-year-old man, who had undergone living-donor liver transplantation (LDLT) twice at age of 43 and 45 years for end-stage liver disease firstly for PSC and secondary for recurrent PSC, suffered liver dysfunction due to an acute cellular rejection (ACR) 17 months after reLDLT...

Epstein-Barr virus (EBV) and human herpesvirus-8 (HHV-8) are γ herpesviruses associated with post-transplant malignancies in kidney transplant recipients. EBV is associated with post-transplantation lymphoproliferative disorder (PTLD), with increased risk in EBV-seronegative patients on intensified immunosuppression. Human herpesvirus-8 is associated with Kaposi's sarcoma (KS), with an increased risk in certain patient populations. Diagnosis of PTLD and KS relies on tissue biopsy. The mainstay of therapy for both PTLD and Kaposi's sarcoma is a reduction of immunosuppression, and in the case of PTLD, consideration of rituximab...

BACKGROUND: Multiple myeloma/plasmacytoma-like posttransplantation lymphoproliferative disorder (PTLD-MM) is a rare complication of solid organ transplantation. Case series have shown variable outcomes, and survival data in the modern era are lacking. PATIENTS AND METHODS: A cohort of 212 PTLD-MM patients was identified in the Scientific Registry of Transplant Recipients between 1999 and 2011. Overall survival (OS) was estimated by the Kaplan-Meier method, and the effects of treatment and patient characteristics on OS were evaluated by Cox proportional hazards models...

Plasma-cell post-transplantation lymphoproliferative disorder (PC-PTLD) is a rare monomorphic PTLD entity divided into plasma cell myeloma (PCM) and plasmacytoma-like lesion (PLL) PTLD. To date, there are no exhaustive published cytogenetic data on PC-PTLD. We report array-based comparative genomic hybridization (aCGH) of 10 cases of PCM and PLL-PTLD. Patients had received kidney (n=6), heart (n=2), lung (n=1) or bone marrow (n=1) transplantation. There were six men and median age at time of PTLD was 56.5 years (3-74)...

Post-transplant lymphoproliferative disorders (PTLD) are a serious complication of transplantation with a high mortality. Most PTLD present within the first year of transplantation and are associated with Epstein-Barr virus (EBV) infection. Plasmablastic lymphoma (PBL) is a rare but aggressive disease originally described in patients with HIV, presenting most commonly in the jaw and oral mucosa. To our knowledge, this is the first case of PBL presenting as PTLD of the lung in a HIV and EBV negative patient...

Patients after lung transplantation are at risk for postoperative malignancy mainly due to postoperative immunosuppression. Skin cancer and post-transplant lymphoproliferative disorder (PTLD) are common in Western countries. We retrospectively reviewed the medical records of 120 patients undergoing lung transplantation between April 2002 and July 2015 at Kyoto University. Postoperative malignancy developed in 14 patients(11.7%):PTLD in 8, gastric cancer in 2, breast cancer in 1, glioblastoma in 1, lung cancer in 1, and adenocarcinoma of unknown primary in 1...

BACKGROUND: Epstein-Barr virus (EBV) displays oncogenic properties, particularly in the immunocompromised host. Notably, hematopoietic stem cell transplantation (HSCT) recipients with a detectable blood EBV viral load (BEBVL) are considered at higher risk of post-transplant lymphoproliferative diseases (PTLD). Therefore, BEBVL is monitored after HSCT, and preemptive rituximab may be used in patients with high values. However, little is known about post-HSCT BEBVL dynamics, and the threshold that should lead to anti-CD20 therapy is poorly defined...

Posttransplant lymphoproliferative disorders (PTLDs) are a heterogeneous group of lymphoid proliferations that occur in the setting of depressed T-cell function due to immunosuppressive therapy used following solid organ transplantation, hematopoietic stem cell transplantation, and also xenotransplantation. In the present study, 28 immunosuppressed parkinsonian Macaca fascicularis were intracerebrally injected with wild-type or CTLA4-Ig transgenic porcine xenografts to identify a suitable strategy to enable long-term cell survival, maturation, and differentiation...

Post-transplant lymphoproliferative disease (PTLD) is a severe complication after solid organ transplantation (SOT). Classical Hodgkin lymphoma-type (HL-) PTLD is a rare subtype, and systematic data on treatment and prognosis are lacking. We report on 17 pediatric patients with classical HL-PTLD. HL-PTLD developed late at a median of 8.1 years after SOT. It was commonly EBV-positive (16/17) and expressed both CD30 (all tumors) and CD20 (8/17 tumors). Patients were treated with chemotherapy +/- involved field radiotherapy (IF-RT) according to the respective GPOH-HD protocol tailored by stage and LDH...

Post-transplant lymphoproliferative disorder (PTLD) is an aggressive complication of solid organ and hematopoietic stem cell transplantation that arises in up to 20% of transplant recipients. Infection or reactivation of the Epstein-Barr virus (EBV), a ubiquitous human herpesvirus, in combination with chronic immunosuppression are considered as the main predisposing factors, however insight in PTLD biology is fragmentary. The study of PTLD is complicated by its morphological heterogeneity and the lack of prospective trials, which also impede treatment optimization...

Posttransplant lymphoproliferative disorder (PTLD) is not uncommon in pediatrics. This case report describes a case of intestinal intussusception that occurred secondary to lymphoid hyperplasia in a child with PTLD following a cardiac transplant. This case was unique in its presentation with multiple areas of intussusception and with need for surgical intervention. The diagnosis of intussusception secondary to lead points from PTLD should be strongly considered in pediatric transplant patients presenting with abdominal complaints...

The number of kidney transplant recipients (KTRs) after nonrenal solid organ transplantation (SOT) has increased to almost 5%. Knowledge on patient and allograft outcomes, infections, and alloreactivity, however, remains scarce. We studied 40 KTRs after nonrenal SOT. 720 primary KTRs and 119 repeat KTRs were used for comparison. Samples were collected pretransplantation, at +1, +2, and +3 months posttransplantation. Alloreactive and CMV-specific T-cells were measured by interferon-γ Elispot assay. Patient survival in KTRs after SOT, primary and repeat KTRs was comparable...

Voided urine is routinely collected from renal transplant patients to screen for polyomavirus. In rare cases, atypical lymphoid cells can be detected in voided urine and raise the suspicion of post-transplant lymphoproliferative disorder (PTLD). However, further immunohistochemistry of the cell block and flow cytometry is frequently limited by the low cellularity and poor preservation of voided urine. Therefore, PTLD of the renal allograft is usually diagnosed from tissue biopsy or nephrectomy specimens. Herein, we report a rare case of atypical cells in a voided urine cytology specimen from a kidney transplant recipient...

BACKGROUND: Because of the strikingly increased risk of post-transplant lymphoproliferative disorder (PTLD) in Epstein-Barr virus (EBV)-seronegative kidney transplant recipients (KTRs) from EBV-seropositive donors-EBV(D(+) R(-) ), special strategies need to be defined to prevent EBV transmission and EBV viremia. METHODS: We studied all KTRs at our center between 2008 and 2012. Seventeen of 402 KTRs (4.2%) were identified as EBV(D(+) R(-) ), among which 5 KTRs received kidneys from living donors and 12 KTRs from deceased donors...
