Abstract
Introduction The aim of our study is to explore the relationship of rabbit anti-thymocyte globulin (R-ATG) on development of post-transplant lymphoproliferative disease (PTLD) and its aggressive forms (monomorphic PTLD and Hodgkin lymphoma) in renal transplant recipients. Methodology All patients diagnosed with PTLD post-renal transplant in the United States’ Organ Procurement and Transplantation Network from 2003 till 2013 and followed up till 2017 were retrospectively reviewed. Multi-variable logistic regression analysis assessed association of R-ATG to development of PTLD and its aggressive form. Results Risk of developing PTLD post renal transplant is 1.35%. In comparison to interleukin-2 blocker induction therapy, R-ATG is associated with increased risk of development of PTLD (Odds Ratio = 1.48, confidence interval ranges from 1.04 to 2.11, p = .02) and is associated with higher risk of development of aggressive PTLD (Odds Ratio = 1.83, confidence interval ranges from 1.001 to 3.34, p = .04). Conclusion We conclude that R-ATG induction is associated with a higher risk of PTLD and its aggressive form (monomorphic PTLD and Hodgkin lymphoma). Careful monitoring for development of PTLD in renal transplant recipients receiving R-ATG induction therapy is advised.

Abstract
Post‑transplant lymphoproliferative disorder (PTLD), despite its rarity, is an important mortality/morbidity event in transplant patients. The purpose of the present study was to retrospectively examine the clinical and pathologic characteristics, and outcomes of PTLD at the Portuguese Oncology Institute of Porto. A retrospective review of patient information was performed for patients that developed PTLD following allogeneic hematopoietic stem cell transplant (aHSCT) and were diagnosed between 2005 and 2012. The present study included a total of 15 patients, 8 females (53.3%) and 7 males (46.7%), with different clinicopathological characteristics. The most frequent clinical condition inducing aHSCT was acute lymphocytic leukemia (40.0%). Conditioning regimens consisted primarily in busulfan and cyclophosphamide, with anti‑thymocyte globulin, and myeloablation was the preferential treatment. Epstein‑Barr virus (EBV) was present in all patients with a median time of diagnosis following transplant of 75 days (range, 25‑485 days) and a median viral load of 4.75 log10 copies/ml (range, 3.30‑6.26 log10 copies/ml). PTLD diagnosis was mainly assessed by clinical findings, and histological confirmation was available for 5 patients: 3 monomorphic, 1 polymorphic and 1 with early lesions of PTLD. To the best of our knowledge, this is the first study to describe PTLD cases in HSCT patients in Portugal. The data reinforces the importance of performing EBV monitoring in high‑risk patients, particularly those receiving a transplant from mismatch/unrelated donors, and those with myeloablative conditioning regimen including antithymocyte globulin. The results also suggested that EBV viral load may be significant for the prediction of PTLD development.

Abstract
Renal transplant recipients exhibit an increased risk of developing plasma cell neoplasms (PCNs; comprising multiple myeloma and plasmacytoma); however, multiple myeloma manifesting with refractory extramedullary plasmacytomas associated with Epstein-Barr virus are markedly rare in these patients. In the present case report, an unusual case of refractory multiple myeloma with multiple extramedullary plasmacytoma (including liver, vertebrae, breast, muscle, skin and soft tissues) was presented. The patient exhibited mild bone marrow infiltration which was successfully treated with novel agents, including bortezomib and lenalidomide, followed by autologous stem cell transplantation (ASCT). In addition, the patient was a renal transplant recipient who achieved a partial clinical remission with controllable therapy-related toxicity effects. Therefore, the present case indicated that ASCT is an effective and safe salvage therapy for renal transplant recipients with secondary extramedullary plasmacytomas and who are resistant to traditional chemotherapy (bortezomib and lenalidomide). ASCT was well-tolerated in the renal transplant recipient.

Abstract
INTRODUCTION Post-transplant lymphoproliferative disorder (PTLD) is the most common form of lymphoproliferation in childhood and is associated with significant morbidity and mortality. In this report we reviewed the case of a pediatric patient who experienced PTLD after allogeneic hematopoietic stem cell transplantation (HSCT) from a human leukocyte antigen (HLA)-identical sibling. METHODS The clinical characteristics, diagnosis, and treatment of PTLD after sibling HSCT in a 4-year-old boy with severe β-thalassemia was retrospectively reviewed. RESULTS Medical records revealed the patient developed a fever and superficial lymphadenopathy and soft palate enlargement 8 months post-HSCT. Pathologic diagnosis indicated non-Hodgkin lymphoma (B-cell type), which resulted in a reduced dose of immunosuppressant and the initiation of chemotherapy (administered according to the BFM95 protocol for 2 courses; 4 courses of rituximab therapy was also administered). Currently, the patient has been disease-free for over 3 years. There are no specific guidelines for the treatment of PTLD. The status of stem cell implantation after transplantation, and graft versus host disease should be evaluated jointly, and rituximab therapy and chemotherapy with BFM-95 may be used for treatment of pediatric PTLD after HSCT. CONCLUSION The current case represents a unique opportunity to review a pediatric patient with β-thalassemia. The successful treatment of post-transplant non-Hodgkin B lymphoma may help other physicians in the management of similar pediatric cases.

Abstract
Post-transplantation lymphoproliferative disease (PTLD) is a serious complication following hematopoietic stem cell transplantation (HSCT). The majority of the cases develop during the first year after the transplantation and are associated with reactivation of the Epstein-Barr virus (EBV); the EBV-induced lymphoproliferation usually includes donor-derived B cells. We herein describe the case of a 28-year-old female patient who developed EBV-negative PTLD, namely diffuse large B-cell lymphoma (DLBCL), 6 months after receiving a haploidentical HSCT from her father. Chimerism analysis performed with XY fluorescence in situ hybridization revealed a B-cell PTLD originating from the donor. Unfortunately, the donor also developed DLBCL 380 days after donating progenitor cells, although he was hematologically normal at the time of donation. The present case demonstrated that disease transmitted from the donor may be a possible cause of PTLD.

Abstract
BACKGROUND The incidence of posttransplant lymphoproliferative disorders (PTLD) has recently declined, but late cases are increasingly reported in lung transplant recipients. OBJECTIVES We present our experience with PTLD after lung transplantation, attempting to examine the distinguishing characteristics of early versus late cases. METHODS We have reviewed clinical and pathological data of all cases occurring in our institution between 2001 and 2014. RESULTS Patients, aged 15-63 years, were mostly (12/16) Epstein-Barr virus (EBV) seropositive at the time of transplantation. Eleven early cases, occurring 9.4 ± 5.2 months after transplantation and mostly (9/11) prior to 2010, had EBV+ diffuse large B-cell lymphomas. Lungs and/or thoracic lymph nodes were often involved (n = 8). Treatments included reduction of immune suppression (n = 11), rituximab (n = 8) and chemotherapy (n = 7). Two patients are in complete remission at 26 and 216 months. Nine patients died 8.0 ± 6.5 months after PTLD diagnosis. Of the 5 cases with late PTLD occurring 4-23 years (mean ± SD: 10.4 ± 7.7) after transplantation (and 3/5 after 2009), 1 had pulmonary lymphomatoid granulomatosis (only endothoracic case), 1 cutaneous large T-cell lymphoma, 2 had anaplastic large cell lymphomas, and 1 Hodgkin's disease. Two of the 5 cases were EBV-, including one followed by a second EBV+ PTLD after 8 years of complete remission. Two patients were alive and well (follow-up: 44 and 151 months), one having suffered from EBV-related cholestatic hepatitis 6 years after the PTLD. CONCLUSION Our small experience shows a trend toward (very) late occurrence, associated with more unusual clinicopathologic features, but not with a worse prognosis.

Abstract
Post-transplant lymphoproliferative disorder (PTLD) is a heterogeneous group of lymphoid proliferations caused by immunosuppression after solid organ or bone marrow transplantation. PTLD is categorized by early lesion, polymorphic PTLD and monomorphic PTLD. Fluorine-18 fluorodeoxyglucose-positron emission tomography/computed tomography (F-18 FDG-PET/CT) scans have clinical significance in the evaluation of PTLD following renal transplantation. We report imaging findings of a monomorphic non-Hodgkin lymphoma, post renal transplant seen on FDG PET/CT in a 32-year-old lactating woman. Whole body FDG- ET/CT demonstrated uptake in right external iliac and inguinal lymph nodes.

Abstract
OBJECTIVES To explore posttransplant lymphoproliferative disorder (PTLD) cases associated with Epstein-Barr virus (EBV). METHODS We retrospectively reviewed the EBV DNA quantitation data of 9,779 blood samples from 740 transplant patients and their associations with PTLD. RESULTS EBV viremia occurred more frequently in patients with PTLD (85.4%) in comparison with patients without PTLD (38.3%; P < .0001). Patients with PTLD demonstrated significantly higher first positive results, higher peak levels, and a higher rate of increase in EBV viral load compared with patients without PTLD (P = .002, P < .0001, and P < .0001, respectively). However, in the multivariate analysis, only the peak level was associated with the development of PTLD. In particular, within hematopoietic stem cell recipients, the peak level able to diagnose PTLD was an area under the receiver operating characteristic curve of 0.806. CONCLUSIONS We believe that pattern analysis of EBV DNA quantitation results could lead to the early diagnosis and timely treatment of PTLD.

Abstract
Posttransplant lymphoproliferative disorders (PTLDs) are a group of diseases that range from benign polyclonal to malignant monoclonal lymphoid proliferations. They arise secondary to treatment with immunosuppressive drugs given to prevent transplant rejection. Three main pathologic subsets/stages of evolution are recognised: early, polymorphic, and monomorphic lesions. The pathogenesis of PTLDs seems to be multifactorial. Among possible infective aetiologies, the role of EBV has been studied in depth, and the virus is thought to play a central role in driving the proliferation of EBV-infected B cells that leads to subsequent development of the lymphoproliferative disorder. It is apparent, however, that EBV is not solely responsible for the “neoplastic” state. Accumulated genetic alterations of oncogenes and tumour suppressor genes (deletions, mutations, rearrangements, and amplifications) and epigenetic changes (aberrant hypermethylation) that involve tumour suppressor genes are integral to the pathogenesis. Antigenic stimulation also plays an evident role in the pathogenesis of PTLDs. Plasmacytoid dendritic cells (PDCs) that are critical to fight viral infections have been thought to play a pathogenetically relevant role in PTLDs. Furthermore, regulatory T cells (Treg cells), which are modulators of immune reactions once incited, seem to have an important role in PTLDs where antigenic stimulation is key for the pathogenesis.

Abstract
A 33-year-old Chinese male patient with severe aplastic anemia received matched sibling allogeneic hematopoietic stem cell transplantation using antithymocyte globulin containing conditioning regimen after 4 months of unsuccessful treatment with cyclosporine A. Following transplantation, the patient was immunosuppressed demonstrated by intermittent infections, including a varicella 3 months after transplantation. Although DNA-STR results on day +30 confirmed complete donor engraftment, repeat DNA-STR analysis performed more than 3 months after transplantation showed a mosaic phenotype. Cyclosporine tapering commenced early, but the last DNA-STR result confirmed complete graft rejection. On day +198, the patient presented with fever, skin boil in the right temporal region, severe pancytopenia, intrabodominal lymphadenopathy and hepatosplenomegaly. Within 1 month, superficial lymphadenopathy and right exophthalmos developed. Excisional lymph node biopsy pathology confirmed Kaposi's sarcoma (KS). The patient succumbed due to intracranial bleeding as a result of thrombocytopenia. This is the first study of KS that developed following stem cell transplantation for severe aplastic anemia. The precipitating factors underlying KS development in this case and its differentiation from post-transplant lymphoproliferative disorders are analyzed.
