Goldbloom syndrome is a rare clinical entity, of unknown etiology that happens almost exclusively in pediatric population. It is a prolonged febrile syndrome with periosteal hyperostosis and dysproteinemia, and often simulates an hematooncology or lymphoproliferative disease. The diagnosis is to rule out the different causes of bone pain associated with hypergammaglobulinemia, hypoalbuminemia, high erythrocyte sedimentation rate and periostitis at the radiographies. Symptomatology, radiology and laboratory parameters refer in a variable time, usually from 3 to 12 months...

Castleman's disease (CD) is a lymphoproliferative abnormality, also referred to as giant lymph node hyperplasia or follicular lymphoid hyperplasia. The occurrence of CD in the liver is rare. Radiological diagnosis of hepatic CD by computed tomography (CT) and magnetic resonance imaging (MRI) remains difficult. On imaging, hepatic CD is often expressed as a single, well-defined soft tissue lesion, with rare cystic degeneration and focal necrosis. The CD lesions appear as hypervascular with abundant cell proliferation on CT and MRI...

The activated phosphoinositide 3-kinase δ syndrome (APDS), also known as p110δ-activating mutation causing senescent T cells, lymphadenopathy, and immunodeficiency (PASLI), is a combined immunodeficiency syndrome caused by gain-of-function mutations in the phosphoinositide 3-kinase (PI3K) genes PIK3CD (encoding p110δ: APDS1 or PASLI-CD) and PIK3R1 (encoding p85α: APDS2 or PASLI-R1). While the disease is clinically heterogeneous, respiratory symptoms and complications are near universal and often severe...

Castleman's disease (CD) is an uncommon benign lymphoproliferative disorder which most commonly involves the mediastinum but rarely affects the pleura. We report a case of unicentric CD that presents as a pleural mass in a 45-year-old man, which was subsequently resected followed by an unexpected diagnosis on histologic examination. Although rare, CD should be included in the differential diagnosis of well-enhancing pleural mass.

In patients with end-stage renal disease, the treatment of choice for most patients is renal transplantation. Complications that occur after kidney transplant can be broadly divided into vascular and non-vascular categories. Non-vascular complications can further be divided into surgical and medical categories. When evaluating renal transplant imaging, it is helpful to consider the occurrence of complications in a timeline from time of surgery. Ultrasound is often the first modality used for evaluation of renal transplants particularly in the early postoperative period...

A 49-year-old man was admitted to our hospital with pancreatitis. He was diagnosed with systemic lupus erythematosus at 34 years of age and was being treated with oral tacrolimus (3 mg/day) and predonine (10 mg/day) for the past 15 months. The computed tomography (CT) scan showed the mass lesion had invaded the pancreatic head via thickening of the duodenal wall. Upper gastrointestinal endoscopy showed the all-round ulcerative lesion from the superior duodenal angle to the descending portion. Histological examination confirmed the diagnosis of diffuse large B cell lymphoma (DLBCL)...

Lymphomatoid granulomatosis (LYG) is a rare B-cell lymphoproliferative disorder driven by Esptein-Barr virus (EBV) that most commonly affects the lungs, although extra pulmonary sites like the central nervous system, skin, liver and kidney can also be involved. It is microscopically characterized by an angiocentric and angiodestructive growth pattern, predominantly composed by small T-cells, although a smaller population of atypical large B-cells is considered the true neoplastic component. Oral cavity involvement of LYG has rarely been described and the diagnosis of this neoplasm is very difficult...

BACKGROUND: Anti-TNF (Tumor necrosis factor) therapy is effective in treating pediatric patients with refractory rheumatic disease. There is however a concern that anti-TNF usage may increase the risk of malignancy. Reports on specific types of malignancy in this patient population have been emerging over the past decade, but there is a need for additional malignancy reports, as these events are rare. Therefore, a retrospective chart review was performed on the biologic database of pediatric rheumatology patients at The Hospital for Sick Children (SickKids) from 1997 to 2013 for neoplasms, patient demographic information and rheumatologic treatment course...

Adalimumab is a fully human chimeric tumor necrosis factor inhibitor used to treat immune-mediated disorders such as psoriatic arthritis. We present a 51-year-old woman with psoriatic arthritis on methotrexate and infliximab for 12 years. Adalimumab replaced infliximab because of worsening symptoms. Following 3 doses administered 1 week apart, rapidly enlarging cervical lymph nodes developed. Biopsy revealed Epstein-Barr virus-related polymorphic lymphoproliferative disorder. F-FDG PET/CT demonstrated widespread hypermetabolic lymphadenopathy; follow-up at 5 weeks off adalimumab revealed almost complete resolution of this adenopathy...

Epstein-Barr virus related post-transplant lymphoproliferative disorders (EBV-PTLDs) are rare but potentially fatal complications of allogeneic hematopoietic stem cell transplantation (allo-HSCT), characterized by uncontrolled proliferation of EBV-infected lymphocytes. The most frequent risk factors include T cell depletion of graft, HLA mismatch, severe graft versus host disease (GVHD), EBV sero-mismatch (recipient-/donor+) and so on. EBV-PTLDs commonly manifest as fever and lymphadenopathy and may rapidly progress to multi-organ failure and even death...

Neurologic complications after solid-organ transplant reveal a great spectrum of pathologies. Intracranial hemorrhages, cerebral ischemic lesions, infarctions, lymphoproliferative disorders, and infections, including aspergillosis, have been observed after liver transplant. Fungi constitute nearly 5% of all central nervous system infections, mainly occurring in immunocompromised patients. The most common causative agent is Aspergillus species. It presents either as maxillary sinusitis or pulmonary infection...

We herein report a patient with a history of rheumatoid arthritis treated with methotrexate, which caused methotrexate-associated lymphoproliferative disorder and obstructive jaundice due to an enlarged lymph node. The obstructive jaundice was treated with endoscopic biliary stenting. A histopathological examination revealed features of Hodgkin's lymphoma, and chemotherapy with brentuximab vedotin was administered. Cholangiography and duodenoscopy after four rounds of chemotherapy revealed a choledochoduodenal fistula that developed in response to chemotherapy...

Plasma cell diseases are a class of hematologic diseases that are sometimes present as pre-existing diagnoses prior to organ transplantation, causative factors leading to a need for organ transplantation, or may occur post-transplant as part of the spectrum of post-transplant lymphoproliferative disorders. Herein, we review the most common plasma cell diseases, both as co-existing with other causes of organ failure, but also as a primary underlying cause for organ failure. In many cases, treatment of the underlying clonal disease may be indicated before proceeding with organ transplant...

The contribution of Epstein-Barr virus (EBV) to the development of specific types of benign lymphoproliferations and malignant lymphomas has been extensively studied since the discovery of the virus over the last 50 years. The importance and better understanding of the EBV-associated lymphoproliferative disorders (LPD) of B, T or natural killer (NK) cell type has resulted in the recognition of new entities like EBV+ mucocutaneous ulcer or the addition of chronic active EBV (CAEBV) infection in the revised 2016 World Health Organization (WHO) lymphoma classification...

BACKGROUND: Post-transplant lymphoproliferative disorder (PTLD) is a potentially life-threatening complication of transplantation occurring in the setting of immunosuppression and oncogenic viral infections. However, little is known about the cumulative incidence, histological subtypes, risk determinants and outcome of PTLD in solid organ transplant (SOT) recipients in Switzerland. METHODS: This retrospective observational study investigated adult SOT recipients from two sequential cohorts, the pre-SCTS (Swiss Transplant Cohort Study) series, with data collected from January 1986 to April 2008, and the STCS series, with data collected from May 2008 to December 2014 in Switzerland...

A systematic review of papers in English on Post-transplant lymphoproliferative disorder (PTLD) in lung transplant recipients (LTR) using MEDLINE, EMBASE, SCOPUS, and Cochrane databases was performed. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations were strictly adhered to. Pooled odds ratios (pOR) were calculated from a random-effects model and heterogeneity among studies was quantitated using I2 values. 14 studies published from 2005 to 2015 were included in the meta-analysis...

RATIONALE: Primary nodal CD4-positive T-cell lymophoproliferative disorder with a relatively indolent process is a rare kind of lymphoproliferative disease. Here we report the first case of a 49 year-old man developed indolent nodal CD4-positive T-cell lymophoproliferative disorder. To our knowledge, based on a careful search of PubMed, it is the first case of primary nodal CD4-positive T-cell lymophoproliferative disorder. PATIENT CONCERNS: A 49-year-old Chinese man presented to our hospital with fever, enlargement of multiple superficial lymphonodes more than 14 years and splenomegaly...

Hepatic pseudolymphoma, also known as reactive lymphoid hyperplasia or nodular lymphoid hyperplasia, is a rare benign lymphoproliferative lesion. Preoperative diagnosis of hepatic pseudolymphoma is challenging. We present 2 cases of hepatic pseudolymphoma with focal intense FDG uptake on FDG PET/CT mimicking malignancy. These 2 cases suggest that hepatic pseudolymphoma should be considered as a rare differential diagnosis in patients with focal hypermetabolic hepatic lesion.

Primary effusion lymphoma (PEL) is a rare type of extranodal lymphoma, typically of a B-cell origin, which presents as lymphomatous effusion with no nodal enlargement or tumor masses. The development PEL is universally associated with human herpes virus-8 (HHV-8) infection. Cases of HHV-8-negative primary lymphomatous effusion have recently been reported and referred to as HHV-8-unrelated PEL-like lymphoma. Some cases of this disease have been reported in iatrogenic immunocompromised patients. The mechanisms responsible for the inhibitory effects of the discontinuation of immunosuppressants other than methotrexate (MTX) against the disease, which have been demonstrated for MTX-associated lymphoproliferative disorders, have not yet been elucidated...

Theileria annulata , a tick-borne apicomplexan protozoan, causes a lymphoproliferative disease of cattle with high prevalence in tropical and sub-tropical regions. Understanding the genetic diversity and structure of local populations will provide more fundamental knowledge for the population genetics and epidemics of protozoa. In this study, 78 samples of T. annulata collected from cattle/yaks representing 6 different geographic populations in China were genotyped using eight micro- and mini-satellite markers...
