BACKGROUND Lymphomas are cancers that arise from the white blood cells and have been traditionally divided into two large subtypes: Hodgkin and non-Hodgkin lymphoma. B-cell lymphoma is the most common subtype of non-Hodgkin lymphoma; almost 85% of patients with lymphoma have this variant. Lymphomas can potentially arise from any lymphoid tissue located in the body; however, primary adrenal non-...

Background: Lymphoma is a malignant proliferation of lymphoid cells. External T-cell lymphoma is very rare. Lymphomas are neoplastic growth of lymphocytes caused by organisms like EBV, HIV, etc. This malignancy is classified as Hodgkin’s lymphoma and non-Hodgkin’s lymphoma. Oral lymphomas account for a small percentage of head and neck malignancies, and intraoral lymphoma is rare and mostly see...

A 33-year-old man presented with a 1-week history of nausea, vomiting, and abdominal distension. Initial laboratory tests were significant for white blood cell count (12×109/L), creatinine (1.4mg/dL), and lactic acid dehydrogenase (2014U/L). Computed tomography scan showed severe thickening of the gastric body, ascites, and peritoneal induration (●" Fig.1a). Based on these findings the patient ...

PURPOSE The clinical success of the first-in-class proteasome inhibitor bortezomib (VELCADE) has validated the proteasome as a therapeutic target for treating human cancers. MLN9708 is an investigational proteasome inhibitor that, compared with bortezomib, has improved pharmacokinetics, pharmacodynamics, and antitumor activity in preclinical studies. Here, we focused on evaluating the in vivo a...

Background: Non-Hodgkin’s lymphoma (NHLs) is known as a heterogeneous group of malignant lymphoproliferative disorders. NHLs are classified into B cell and T cell types. Immunophenotypical assessment of the biopsy specimens can help diagnose NHLs.    Methods: In this study, 77 patients with B cell and T cell lymphoma were selected from Shahid Sadoghi hospital during 2010 to 2...

Uterine lymphoma is a rare disease therefore, information regarding histologic type, immunophenotype of tumor cells and etiologic factors are limited. although secondary involvement of the genital tract occurs in up to 40% of cases• of disseminated lymphoma, lymphoma presenting with primary female genital tract . symptomatology is very unusual. We report a case of B-cell lymphoma in the ut...

malignant lymphoma is the neoplastic transformation of cells, mostly originating from lymphoid tissues. malignant lymphoma has two major subtypes: hodgkin and non-hodgkin lymphoma. malignant lymphoma is the most common neoplasm in 3rd and 4th decades of life and more than two third of affected patients presented painless peripheral lymphadenopathy. involvement of waldeyer’s ring, epitrochlear a...

Genetic instability is a characteristic feature of the malignant Hodgkin and Reed-Sternberg (HRS) cells in classical Hodgkin's lymphoma and the lymphocytic and histiocytic (L&H) cells in lymphocyte predominant Hodgkin's lymphoma. Genetic instability can be classified into four major categories: distinct DNA mutations (microsatellite instability); numerical aberrations (chromosomal instability);...

Abstract Introduction: Extra-nodal exposition of T-cell non-hodgkin lymphoma (NHL) is extremely rare, and is frequently observed in patients with immune system dysfunction. Peripheral T-cell lymphoma does not express CD56 is rare. Malignant lymphoma of the uvula is exceedingly unusual. The current study reported a case of peripheral T-cell lymphoma of the uvula in an immunecompetent patient. ...
