background : there are only a few reports that exist regarding primary non-hodgkin lymphoma of the genital tract. in this article, one case of primary b-cell type non-hodgkin lymphoma (nhl) of the cervix is presented. case history: a 45 year-old woman presented bloody vaginal  discharge. upon vaginal examination, the cervix was found to be enlarged. cervical biopsy revealed b-cell type non-hodg...

non hodgkin lymphomas (nhl) are nodal or extra nodal monoclonal infiltrations by malignant lymphoid cells (b lymphocytes in 80% of cases), which are distinguished as indolent or aggressive forms. according to the heterogeneity of lymphoid cells and their ubiquitous anatomical distribution, these disorders can develop in any organ and have very heterogeneous clinical expressions, but they are us...

constrictive pericarditis (cp) is an uncommon post inflammatory disorder. it is described as pericardial thickening, myocardial constriction, and impaired diastolic filling. the most common etiologies are idiopathy, mediastinal radiotherapy, and prior cardiac surgery. less common etiologies include viral infections, collagen vascular disorders, renal failure, sarcoidosis, tuberculosis, and blun...

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...

background epstein-barr virus (ebv) is a dna virus which belongs to the herpesviridae family and in γ-herpesvirus subfamily, has been infected about 95% of the world’s population. ebv is transmitted through saliva and associated with different disease such as infectious mononucleosis, nasopharyngeal carcinoma, burkitt`s lymphoma, hodgkin and non-hodgkin`s lymphoma. the study proposed to determi...

background and objectives: human herpes 6 virus (hhv-6) could remain latent and chronic in the host cells after primary infection. hhv-6 genome encodes certain trans activation proteins which may results in development of malignantlymphoma. the association of human herpes six virus (hhv-6) infection and hodgkin and non-hodgkin lymphomas is strongly supported by epidemiological studies. the aim ...

conclusions a high rate of 25% and 24.13% of hbv dna was detected among patients with hodgkin and non-hodgkin lymphoma, respectively. results three out of 12 (25%) hodgkin samples and seven out of 29 (24.13%) non-hodgkin showed positive hbv dna results. the results of sequencing revealed that the d genotype was predominant among the positive hbv patients. interestingly an unpredictable amino ac...

  Background and Objectives: Classic Hodgkin lymphoma (CHL), anaplastic large cell lymphoma (ALCL) and some cases of diffuse large B cell lymphoma (DLBCL) have overlapping morphologic features. Since they all represent distinct clinico-pathologic entities, we explored the differential diagnostic impact of immunophenotyping to discriminate between them. Materials and Methods:...

  Primary non-Hodgkin lymphoma of the larynx is rare, accounting for less than 1% of all laryngeal neoplasms. Fewer than 100 cases have been reported in the literatureand to our knowledge this may be the first reported case of laryngeal non Hodgkin lymphoma presented with hoarseness, aortic aneurysm, hepatitis B and skin rashes.

background and objectives: classic hodgkin lymphoma (chl), anaplastic large cell lymphoma (alcl) and some cases of diffuse large b cell lymphoma (dlbcl) have overlapping morphologic features. since they all represent distinct clinico-pathologic entities, we explored the differential diagnostic impact of immunophenotyping to discriminate between them. materials and methods: we included 61 cases ...
