The overlapping features of malignant lymphomas create a diagnostic "grey zone" , and lead to the invention of "grey zone lymphomas". There are several major grey zone lymphomas: 1) Lymphomas with overlapping features of Hodgkin lymphoma and large B-cell lymphoma; 2) Lymphomas with overlapping features of Burkitt lymphoma and diffuse large B-cell lymphoma; 3) Lymphomas with overlapping features...
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...
introduction: burkitt lymphoma (bl) is rare, but an aggressive malignancy. central nervous system burkitt lymphoma (cnsbl) is very rare. cns burkitt’s lymphoma is treated with high-dose chemotherapy and radiation. radiotherapy in children younger than three years old may cause major cns damage. case report: a three-year-old boy presented with painful proptosis of the left eye. he underwent aden...
Primary cutaneous lymphomas rank as the second most common clinical form of extranodal non-Hogdkin malignant lymphomas. Among non-Hodgkin skin T-cell lymphomas, Mycosis Fungoides (MF) is frequent occurence. The MF lymphoma originates in skin-homing helper T-cells, which express CD4 + marker, showing chronic evolution, with recurrent lesions. In advanced stages, patients may experience severe/ex...
Primary soft tissue Non-Hodgkin lymphomas are very rare and account only for 0.1 % of the cases. Generally, Non-Hodgkin lymphomas of the soft tissue present as large subcutaneous masses without evidence of nodal or skin involvement. We describe four cases of primary Non-Hodgkin lymphomas of the soft tissue in patients infected with the human immunodeficiency virus. The most common site of invol...
Connective tissue growth factor (CTGF) has a major role in development of fibrosis and in the wound-healing process. Microarray analysis of 44 classical Hodgkin lymphoma (cHL) samples showed higher CTGF messenger RNA expression in the nodular sclerosis (NS) than in the mixed cellularity (MC) subtype. When analyzed by immunohistochemical analysis, Hodgkin-Reed-Sternberg (H-RS) cells and macropha...
Lymphomas are solid tumors of immune system and Non-Hodgkin Lymphomas (NHL) is the most prevalent lymphomas; with wide ranges of histological and clinical features, it is so difficult to identify them. Herein, various bioinformatics tools (such as gene differential expressions, epigenetics and protein analysis) employed to find new treatment approach for NHL based on gene expression variation b...
Introduction & Objective: The lymphomas are a group of malignant solid tumors that involving cells of the lymphoreticular or immune system. While primary symptoms of lymphoma could involve head and neck region thus have significant value for dentists. The aim of this study was evaluation of the frequency and epidemiologic data of Lymphoma in Hamadan. Materials & Methods: In this retrospectiv...
BACKGROUND The incidence of malignant lymphomas has been increasing rapidly, but the causes of these malignancies remain poorly understood. One hypothesis holds that exposure to ultraviolet (UV) radiation increases lymphoma risk. We tested this hypothesis in a population-based case-control study in Denmark and Sweden. METHODS A total of 3740 patients diagnosed between October 1, 1999, and Aug...
Background : Hodgkin lymphoma is a type of immune system malignancies, constituting about 30% of all cases of lymphomas. It is divided into four subgroups based on histopathologic findings. Recent reports indicate that SDF1 chemokine plays a major role in the development, survival and metastasis of many cancers, including breast, prostate and pancreas. So far, its expression and especially re...
