Children and adolescents with pre-existing conditions such as DNA repair defects or other primary immunodeficiencies have an increased risk of non-Hodgkin lymphoma. However, large-scale data on patients with non-Hodgkin lymphoma and their entire spectrum of pre-existing conditions are scarce. A retrospective multinational study was conducted by means of questionnaires sent out to the national s...

introduction: management of early relapsed or refractory lymphoma [hodgkin & non- hodgkin lymphoma (hl & nhl)] is a matter of problem, especially when hematopietic stem cell support is not available. the aim of this study was to evaluate effectiveness of iev regimen ( ifosfamide, epirubicin, vp16), in lymphoma patients who are not candidate for stem cell transplantation. because the majority of...

INTRODUCTION This study is aimed to assess the prevalence and characteristics of head and neck lymphoma in a defined group of an Iranian population. MATERIALS AND METHODS In this retrospective study, 126,450 biopsy reports from two referral Pathology Departments, (Tehran, the capital of Iran) were evaluated. In cases with head and neck lymphoma, other variables such as age, sex, specific loca...

Profound disruption of immune function is an established risk factor for non-Hodgkin lymphoma. We report here a large-scale evaluation of common genetic variants in immune genes and their role in lymphoma. We genotyped 57 single nucleotide polymorphisms (SNP) from 36 candidate immune genes in 1,172 non-Hodgkin lymphoma cases and 982 population-based controls from a US multicenter study. We calc...

Chylous pleural effusion is characterized by milky-appearing fluid with elevated triglyceride content and presence of chylomicrons in the pleural space. Even though patients with lymphoma sometimes present with malignant pleural effusion, chylous effusion is rarely encountered as a presenting feature in such patients. We present a 47-year-old woman diagnosed as follicular lymphoma who presented...

BACKGROUND The steady worldwide increase in the incidence of non-Hodgkin lymphoma during the past few decades remains mostly unexplained. Several studies suggest that there may be an association between the agricultural use of the organochlorine 1,1,1-trichloro-2,2'bis(p-chlorophenyl)ethane (DDT) and increased risk of non-Hodgkin lymphoma. We have investigated the association between risk of no...

BACKGROUND The International Lymphoma Epidemiology Consortium (InterLymph) provides an opportunity to analyze the relationship between cigarette smoking and non-Hodgkin lymphoma with sufficient statistical power to consider non-Hodgkin lymphoma subtype. The results from previous studies of this relationship have been inconsistent, likely due to the small sample sizes that arose from stratificat...

background: the clinical presentation of non-hodgkin lymphoma (nhl) varies tremendously depending upon the type of lymphoma and the areas of involvement. nhl can rarely present as an abdominal mass compressing the inferior vena cava. the clinical presentation due to obstruction of inferior vena cava has often been called the inferior vena cava syndrome (ivcs). it can present acutely or chronica...

BACKGROUND A possible connection between allergy and cancer has been suspected, but allergy-related conditions or atopy have been inconsistently associated with reduced risks of non-Hodgkin lymphoma. We investigated this association in a population-based case-control study and in a prospective study with prediagnostic blood specimens. METHODS We carried out a population-based study of 3055 ca...

In rare instances, two distinct lymphomas concurrently occur in a patient. Such composite lymphomas can be combinations of two non-Hodgkin lymphomas or a combination of a non-Hodgkin lymphoma and a Hodgkin's lymphoma. Composite lymphomas pose a particular diagnostic challenge, and there are currently no agreed standards for treatment. Combined B-cell non-Hodgkin lymphomas are often clonally unr...
