BACKGROUND: In several studies, dioxin exposure has been associated with increased risk from several causes of death. AIMS: To compare the mortality experience of workers exposed to dioxins during trichlorophenol (TCP) and pentachlorophenol (PCP) production to that of the general population and to examine mortality risk by estimated exposure levels. METHODS: A retrospective cohort study which followed up workers' vital status from 1940 to 2011, with serum surveys to support estimation of historical dioxin exposure levels...

INTRODUCTION: Acute liver failure (ALF) is a rare syndrome involving maximum liver dysfunction. This disease is characterized by a less than 26-week history of coagulopathy (INR ≥1.5) and hepatic encephalopathy and generally occurs in patients without any previously known disease. METHODS: We report the case of a healthy 25-year-old subject who presented with fulminant liver failure caused by a primary non-Hodgkin's lymphoma of the liver that required emergency liver transplantation...

Mantle cell lymphoma (MCL) is a rare and aggressive form of non-Hodgkin lymphoma. It is predominantly a disease of older individuals, with a median age at presentation of ∼70 years. For the majority of patients, the management revolves around immuno-chemotherapy often followed by maintenance rituximab, and at relapse, a range of options are available. For the younger patient, it is possible to be more intensive with therapy, consolidate responses with high-dose procedures, and in a few there might be the prospect of a cure...

Characteristic chromosomal translocations are found to be associated with subtypes of B-cell non-Hodgkin lymphoma (NHL), for example t(8;14)(q24;q32) and Burkitt lymphoma, t(14;18)(q32;q21) and follicular lymphoma, and t(11;14)(q13;q32) in mantle cell lymphoma. Only few recurrent cytogenetic aberrations have been identified in the T-cell NHL and the best known is the ALK gene translocation t(2;5)(p23;q35) in anaplastic large cell lymphoma. Since lymph node or other tissue is seldom submitted for conventional cytogenetics study, alternative approaches for translocation detection are polymerase chain reaction (PCR) or fluorescence in situ hybridization (FISH)...

Conventional cytogenetics is invariably one of the most important methods used in diagnostics of chronic lymphoproliferations. It complements fluorescence in situ hybridization (FISH) and molecular analysis. Presence of particular chromosomal alterations in chronic lymphocytic leukemia enables patients' stratification into appropriate cytogenetic risk groups and influences treatment decisions. In other non-Hodgkin lymphomas cytogenetic analyses are employed also in minimal residual disease assessment.As lymphocytes in chronic lymphoid malignancies are characterized by low proliferation rate in vitro, it is critical to induce their division in the culture properly...

OBJECTIVE: This is an exemplary case report underlining a relevant morbidity which could be associated to the use of autologous iliac crest bone graft (ICBG) for spine fusion. CASE REPORT: Starting from 1990, a 25-years-old woman underwent two subsequent surgical treatments for non-Hodgkin lymphoma vertebral localizations. In the second surgery, arthrodesis was obtained with autograft through right posterior iliac crest osteotomy. During the chemotherapy treatment following the surgery, the patient suffered from infection at posterior iliac crest scar, the site of previous graft, caused by methicillin-resistant Staphylococcus aureus...

BACKGROUND: Non-Hodgkin's lymphomas arising from the tissues other than primary lymphatic organs are named primary extranodal lymphoma. Most of the studies evaluated metabolic tumor parameters in different organs and histopathologic variants of this disease generally for treatment response. We aimed to evaluate the prognostic value of metabolic tumor parameters derived from initial FDG-PET/CT in patients with a medley of primary extranodal lymphoma in this study. PATIENTS AND METHODS: There were 67 patients with primary extranodal lymphoma for whom FDG-PET/CT was requested for primary staging...

Primary renal lymphoma (PRL) is a rare disease, with no more than 70 cases reported in the literature. The present study reports the case of a 70-year-old woman with PRL. The patient was asymptomatic, however, a mass on the right kidney was identified incidentally during routine physical examination. Computed tomography revealed a mass in the right kidney that was 3.6 cm in diameter. Subsequently, right nephrectomy was performed. The histological evaluation of the nephrectomy specimen showed diffuse large B-cell non-Hodgkin's lymphoma...

The tracheobronchial origin of non-Hodgkin's lymphoma (NHL) is a very rare presentation, and there are only a few case reports of primary tracheal or endobronchial NHL. We have two cases of primary tracheobronchial NHL; one case was incidentally diagnosed as anaplastic large cell lymphoma of endobronchial origin when a comprehensive workup and surgery were carried out for an endobronchial aspergilloma which was actually sitting on top of lymphoma. The second patient was a case of myelodysplastic syndrome who presented with acute respiratory distress; on thorough workup, he was found to have endotracheal B-cell lymphoma...

In this literature review, we reported autoimmune and inflammatory disorders associated with lymphoid hematological malignancies, including non-Hodgkin's lymphoma, Hodgkin's lymphoma and chronic lymphocytic leukemia. The different types of systemic involvement are classified by affected organ. We listed in this review the joint diseases, skin, neurologic, hematologic, renal, and vasculitis. We tried to determine whether there is a correlation between each autoimmune manifestation and a specific type of lymphoma or a particular feature that may support a paraneoplastic origin, if there is an impact on the prognosis of the hematological malignancy, and finally, we identified the different therapeutic strategies used in the literature...

REVIEW
Julia Carnevale, James L Rubenstein
Primary central nervous system (CNS) lymphoma is a challenging subtypes of aggressive non-Hodgkin lymphoma. Emerging clinical data suggest that optimized outcomes are achieved with dose-intensive CNS-penetrant chemotherapy and avoiding whole brain radiotherapy. Anti-CD20 antibody-based immunotherapy as a component of high-dose methotrexate-based induction programs may contribute to improved outcomes. An accumulation of insights into the molecular and cellular basis of disease pathogenesis is providing a foundation for the generation of molecular tools to facilitate diagnosis as well as a roadmap for integration of targeted therapy within the developing therapeutic armamentarium for this challenging brain tumor...

A small percentage of nodular lymphocytic predominant Hodgkin lymphoma (NLPHL) progresses to diffuse large B-cell lymphoma (DLBCL). There have also been rare reports of gray zone lymphoma with features intermediate between classical Hodgkin lymphoma (CHL) and DLBCL. We report a very rare case of composite lymphoma (CHL and NLPHL) progressing to DLBCL, and highlight the diagnostic difficulty faced during its fine-needle aspiration (FNA) cytology diagnosis. A 65-year-old woman presented with a right axillary swelling which was subjected to FNA cytology...

Lymphomatosis cerebri (LC) is a rare variant of a primary central nervous system non-Hodgkin's lymphoma (PCNSL) characterised by diffuse infiltration of tumour cells throughout the brain parenchyma. We present a 68-year-old immunocompetent woman with headaches, dizziness, blurred vision, localised right leg weakness and rapidly progressive dementia. A brain MRI demonstrated diffuse T2 hyperintense white matter lesions that did not enhance with contrast. The clinical differential diagnosis of these lesions included metastatic disease, infectious or inflammatory process such as sarcoidosis, lymphoma, demyelinating disease and less likely vascular aetiology, such as vasculitis or ischaemic stroke...

Interim and end-of-treatment PET/CT have become central to the evaluation of Hodgkin's and non-Hodgkin's lymphoma. This review article seeks to aid clinical decision-making by providing an overview of available data on the diagnostic and prognostic value of PET/CT imaging for response assessment and pre-transplant evaluation in lymphoma. The relative strengths and limitations of these techniques in various disease subtypes and clinical scenarios are explored, along with their current standards for reporting and latest developments...

BACKGROUND: Pediatric patients with non-Hodgkin lymphoma (NHL) in developing countries (DCs) present with greater tumor load even at lower stages and with comorbidities that impact therapy delivery. This causes toxic mortality with "standard" intensive protocols or recurrences with "gentler" treatment. OBJECTIVES: We developed and evaluated a risk stratification schema that guides intensity of therapy. DESIGN/METHODS: Sixty-nine patients were prospectively assigned to five risk groups (A-E; n = 6, 15, 16, 15, and 17) following staging and treated with protocols of risk-stratified intensity...

Since it was discovered that UV radiation was the main environmental cause of skin cancer, primary prevention programs have been started. These programs advise to avoid exposure to sunlight. However, the question arises whether sun-shunning behaviour might have an effect on general health. During the last decades new favourable associations between sunlight and disease have been discovered. There is growing observational and experimental evidence that regular exposure to sunlight contributes to the prevention of colon-, breast-, prostate cancer, non-Hodgkin lymphoma, multiple sclerosis, hypertension and diabetes...

BACKGROUND: Non-Hodgkin lymphomas (NHL) are the most frequent hemato-oncological malignancies. Despite recent major advances in treatment, a substantial proportion of patients relapses highlighting the need for new therapeutic modalities. Promissory results obtained in pre-clinical studies are usually not translated when moving into clinical trials. Pre-clinical studies are mainly conducted in animals with high tumor burden; instead patients undergo chemotherapy as first line of treatment and most likely are under remission when immunotherapies are applied...

Immunotherapy using engineered autologous T cells has been attempted for decades, but clinical trials have only recently demonstrated efficacy. The combination of enhanced manufacturing techniques, highly efficient engineering, appropriate target selection and synthetic receptors with potent T cell activating domains has led to the development of highly-active cellular therapy products. B-cell malignancies have served as the paradigmatic diseases to initially evaluate and subsequently hone engineered T cells targeting cancer...

BACKGROUND: Peripheral T-cell lymphomas, not otherwise specified (PTCL-NOS), are a rare condition characterised by specific histology, nodal presentation, and a poor prognosis. In total, 10-18% of patients present with cutaneous involvement which is regarded as a poor prognostic marker. However, cutaneous PTCL-NOS lesions have been rarely reported in the literature. OBJECTIVES: We sought to describe PTCL-NOS cases characterised by erythrodermic dissemination to the skin...
