BACKGROUND To evaluate the role of flow cytometric immunophenotyping (FCI) in diagnosis and characterization of lymphoma tissue specimens from Egyptian patients. METHODS FCI using 2 and 3 color staining approaches, was performed on 50 fresh lymph nodes specimen from Cairo NCI patients with suspected lymphoma presenting with either localized or generalized lymphadenopathy.FCI results were corr...

Secondary kidney involvement by disseminated non-Hodgkin's lymphoma (NHL) is quite common and is estimated to approach 30 - 60% in NHL patients. However, primary renal lymphoma is exceedingly rare and estimated to make up less than 1% of all kidney masses. We report a case of primary renal NHL presenting with profound hypercalcemia and renal failure recalcitrant to medical management, ultimatel...

Background: Immunophenotyping and improvement in classification system of lymphoma gains better epidemiological comparison incidence pattern. We aimed to study the spectrum clinic-epidemiological profile categorize type subtype according 2008 WHO system. Methods: This hospital-based retrospective, cross-sectional included all cases diagnosed a 5-year period from January 2012 December 2016. Demo...

Primary non-Hodgkin's lymphoma (NHL) of the gastrointestinal tract is the most common extranodal NHL and accounts for 4%-20% of all NHL . Mantle cell lymphoma (MCL) comprises 2.5%-7% of all NHL . Gastrointestinal tract involvement occurred in 20% of MCL, which is commonly manifested as numerous, small, spherical, or hemispherical polyps, termed multiple lymphomatous polyposis (MLP). Hereby we r...

Lymphomas are classified as Hodgkin’s and Non-Hodgkin’s lymphomas (HL NHL) NHL being further sub-divided into B, T and Null cell categories on the basis of WHO classification. With a few exceptions worldwide, B-NHL are more common, accounting approximately 80-85% of all cases of NHL compared to T-NHL, which accounts for about 10-15% of all NHL cases. The incidence of NHL has shown a steady incr...

OBJECTIVE HIV-infected people have greatly elevated risk of non-Hodgkin lymphoma (NHL), particularly the AIDS-defining NHL subtypes: diffuse large B-cell lymphoma, Burkitt lymphoma and primary lymphomas arising in the central nervous system. The goals of this analysis were to comprehensively describe risks of NHL subtypes, especially those not well studied, among HIV/AIDS patients; examine risk...

Among exposures presently viewed as possible etiologic factors in non-Hodgkin lymphoma (NHL), infections are close to being regarded as established causes. Infectious agents causing NHL can be classified, according to mechanism, into three broad groups. First, some viruses can directly transform lymphocytes. Lymphocyte-transforming viruses include Epstein Barr virus (linked to Burkitt's lymphom...

Non-Hodgkin lymphoma (NHL) comprises numerous biologically and clinically heterogeneous subtypes, with limited data examining the risk factors for these distinct disease entities. Many limitations exist when studying lymphoma epidemiology; therefore, until recently, little was known regarding the etiology of NHL subtypes. This review highlights the results of recent pooled analyses examining th...

INTRODUCTION The distribution of the major subtypes of non-Hodgkin's lymphoma (NHL) differs across geographic regions. This study, from the north Indian state of Punjab, has incorporated immunophenotypic findings while investigating the distribution of NHL subtypes based on World Health Organization (WHO)/ Revised European-American Classification of Lymphoid Neoplasms (REAL) system of classific...

The association between some infections and non-Hodgkin lymphomas (NHL) is well known. Human T-cell leukemia/lymphoma virus type 1 (HTLV-1) was the first oncogenic human retrovirus to be discovered and has been found to be associated with adult T-cell leukemia/lymphoma (ATLL). Epstein-Barr virus (EBV) has consistently been linked to both endemic and sporadic Burkitt lymphoma (BL), as well as...
