BACKGROUND: Multicentric Castleman disease (MCD) is an uncommon lymphoproliferative disease characterized by systemic inflammatory reactions associated with the dysregulated production of interleukin-6 (IL-6). In patients with MCD, renal involvement is uncommon, with only one report published regarding kidney transplantation (KTx) to treat end-stage renal disease (ESRD) secondary to MCD. Recent clinical observations have shown that IL-6 production is implicated in allograft rejection, while IL-6 receptor blockade (with tocilizumab [TCZ]) reduces alloantibody generation and thereby improves graft survival; however, the efficacy and safety of TCZ in MCD patients undergoing KTx is still unknown...

This study provides an overview of the epidemiology and secular trends of malignant lymphoma in Japan. Using data from clinics and hospitals throughout Japan, we analyzed 9426 cases of malignant lymphoma diagnosed in 2007-2014. We show that the proportion of follicular lymphoma and methotrexate-associated lymphoproliferative disorder increased during this time, as did the onset age for follicular lymphoma and diffuse large B-cell lymphoma. Significant increases in onset age for follicular lymphoma and diffuse large B-cell lymphoma were observed in both men and women (all P values <0...

An ectopic pancreas, also known as pancreatic rest or heterotopic pancreas, consists of pancreatic tissue found in a location with no continuity with the anatomic pancreas. This lesion can occasionally cause gastrointestinal obstruction, ulceration or become inflamed and cause ectopic pancreatitis. We present the case of a 29-year-old immunocompromised female patient due to a previous kidney transplant. She presented with nausea and vague abdominal discomfort and was admitted for investigation and treatment of an acute kidney injury...

POEMS syndrome (acronym consisting of: polyneuropathy, organomegaly, endocrinopathy, M protein, and skin changes) is an uncommon disorder associated with an underlying plasma cell dyscrasia. There is no single specific test for POEMS, and due to its rarity and heterogeneity, patients are often mis- or underdiagnosed. Castleman disease (CD) is a rare lymphoproliferative disorder, closely related to POEMS syndrome; ~11%-30% of POEMS patients are associated with concomitant CD. In contrast to frequently published reports on vascular events in POEMS syndrome affecting coronary arteries or lower limbs, cases of cerebrovascular events are rarely mentioned in literature...

BACKGROUND: Low-grade alimentary lymphoma (LGAL) is characterised by the infiltration of neoplastic T-lymphocytes, typically in the small intestine. The incidence of LGAL has increased over the last ten years and it is now the most frequent digestive neoplasia in cats and comprises 60 to 75% of gastrointestinal lymphoma cases. Given that LGAL shares common clinical, paraclinical and ultrasonographic features with inflammatory bowel diseases, establishing a diagnosis is challenging. A review was designed to summarise current knowledge of the pathogenesis, diagnosis, prognosis and treatment of feline LGAL...

Castleman's disease (CD) is an uncommon type of lymphoproliferative disorder. Its etiology and prevalence are unclear. The retroperitoneum is a very rare site for presentation of the unicentric variant, where it mimics malignant tumors. A 59-year-old man is referred to the urology outpatient clinic for the study of microhematuria found in a routine analysis. CT scan of the abdomen identified a solid, circumscribed mass, measuring 28 × 30 × 31 mm in the left para-aortic zone, with homogeneous contrast enhancement...

Post-transplantation lymphoproliferative disorder (PTLD) is a well-know complication after organ transplantation. We report a case of a patient who developed an extramedullary plasmacytoma-like PTLD around his transplanted kidney treated with standard multiple myeloma chemotherapy. Three years after benefiting of a deceased donor kidney transplant for an end stage kidney disease secondary to nephroangiosclerosis, our patient developed an extra-medullary plasmacytoma confined to the transplant compartment. The transplant function was unaltered, and due to the absence of reduction of the lesion after immunosuppression reduction, a chemotherapy by bortezomib-cyclophosphamide-dexamethasone (VCD) known to be efficient in multiple myeloma was initiated...

Epstein-Barr virus (EBV) has a well-known association with lymphoproliferative disorders of B and T cell origin. EBV-related B cell lymphoproliferative disorders include Hodgkin and Burkitt lymphomas, lymphomatoid granulomatosis, EBV positive diffuse large cell B cell lymphoma of the elderly, as well as B cell lymphomas associated with solid organ transplantation and methotrexate use. EBV-related T cell disorders are primarily represented by NK/T- cell lymphoma. In a subset of patients, EBV has been implicated in CD30 positive B cell lymphoproliferative disorders of the oral mucosa falling under the rubric of the mucocutaneous ulcer of the oral cavity...

Castleman's disease (CD), a heterogeneous group of lymphoproliferative disorders, is divided into unicentric CD (UCD) and multicentric CD (MCD) based on the number of regions of enlarged lymph nodes with characteristic histopathologic features. The clinical pictures and treatment differ greatly between these UCD and MCD. In MCD, cases of human herpesvirus 8-negative patients with unknown etiology are defined as idiopathic MCD (iMCD). Most cases of UCD are treatable by surgical excision. The prognosis of iMCD varies, and it may be challenging to achieve remission...

Kaposi's sarcoma-associated herpes virus (KSHV) is a gammaherpesvirus associated with Kaposi's sarcoma and various lymphoproliferative diseases. Epithelial-to-mesenchymal transition (EMT) is an important step in the metastasis of cancer cells. Previous studies have shown an important role for EMT markers in B-cell malignancies. In the present study, we investigated the role of the KSHV latent protein LANA in the progression of EMT. Our data suggest that expression of LANA results in an increase in the migration and invasion potential of cancer cells, which is concurrent with modulation of transcriptional regulation and protein expression of several cellular genes associated with EMT...

RATIONALE: Type I cryoglobulinemia is a rare and life-threatening condition. It occurs mainly in B-cell lymphoproliferative disorder. In almost half of the patients, type I cryoglobulinemia is characterized by severe cutaneous involvement. PATIENT CONCERNS: A 71-year-old man comes to our observation because of the onset of persistence of paresthesia and painful acrocyanosis in the fingers and toes. IgG-k multiple myeloma treated with chemotherapy and radiation therapy on the left iliac wing characterized his clinical history...

Posttransplant lymphoproliferative disease (PTLD) is an uncommon complication of immunosuppression after solid organ transplantation. Early PTLD (<1 year after transplantation) is frequently found around the allograft, whereas late PTLD (>1 year after transplantation) does not have such a preference. 18-Fluorodeoxyglucose positron emission tomography-computed tomography (18 FDG PET-CT) has clinical significance in the evaluation of PTLD. 18 FDG PET-CT scan allows precise anatomic localization of FDG-avid lesions, hence helpful in staging of disease and evaluation of response to therapy...

Posttransplant lymphoproliferative disorder (PTLD) is reported in 1%-3% among pediatric renal allograft recipients. We report the experience of PTLD among pediatric renal allograft recipients at a pediatric nephrology center in North India. Four cases of PTLD were identified from among records of 95 pediatric renal allograft recipients over a period of 21 years. Constitutional and localizing symptoms were present in three patients each. The diagnosis was suggested on positron emission tomography in three patients and confirmed by histopathology in all...

Actinomycosis is a chronic, suppurative, inflammatory granulomatous disease caused by gram positive anaerobic filamentous bacteria of the genus Actinomyces, most frequently Actinomyces israelii. We report a case of a 42-year-old male presenting with abdominal pain, a 10kg weight loss and a fixed mass in the epigastrium. Tomography revealed dilatation of the intestinal loops and thickening of the colon walls; the coexistence of these two findings suggested a lymphoproliferative process. The tumour, ileum fragment and colon were surgically removed; these were adherent to the serosal fibro-adipose tissue...

Celiac disease is a chronic inflammation of the small intestine with villous atrophy that can become refractory to a gluten-free diet. Two categories of refractory celiac disease (I and II) can be distinguished by the phenotype of intra-epithelial lymphocytes and the status of TRG genes. Their distinction is important because 30% to 50% of type II, but only 0% to 14% of type I, evolve to an aggressive enteropathy-associated T-cell lymphoma and therefore require intensive treatment. Currently, differential diagnosis integrates immunohistochemistry, immunophenotyping, and TRG clonality analyses but each have limitations...

Background Epstein-Barr virus (EBV) DNA load monitoring in blood is essential for the diagnosis of EBV-associated diseases. However, the best-suited blood compartment for detection is still under discussion. The aim of this study was to evaluate the diagnostic value of EBV-DNA load in peripheral blood mononuclear cells (PBMC), plasma and whole blood (WB) samples. Methods A total of 156 patients, including 45 patients with infectious mononucleosis (IM), 57 patients with EBV-associated hemophagocytic lymphohistiocytosis (HLH) and 54 patients with post-transplant lymphoproliferative disorders (PTLD), were enrolled in this study...

Background: The first-line treatment in cases of chylous leakage is conservative, and operation should be considered only in patients who fail to respond to this treatment. The main clinical concern is the difficulty of intraoperative localization of the site of leakage that can affect surgical outcome. Case Presentation: A 33-year-old man presented with a 4-month history of abdominal pain and weight loss. CT scan revealed enlarged retroperitoneal lymph nodes. Retroperitoneal lymph node biopsy was performed owing to the suspicion of lymphoproliferative disease, with a pathological result of nonspecific adenitis...

Autologous T cells targeting Epstein Barr virus (EBV) latent membrane proteins (LMPs) have shown safety and efficacy for the treatment of patients with type II latency EBV-associated lymphomas who have failed standard therapies, including high dose chemotherapy followed by autologous stem cell rescue. However, the safety and efficacy of allogeneic donor-derived LMP-specific T cells (LMP-Ts) have not been established for patients who have received allogeneic HSCT. Thus, we evaluated the safety and efficacy of donor-derived LMP-Ts in 26 patients who had received an allogeneic hematopoietic stem cell transplant (HSCT) for EBV-associated T/NK or B cell lymphomas (NCT00062868, NCT01956084; ClinicalTrials...
