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 ...

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...

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 lo...

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...

non-hodgkin lymphoma usually presents with generalized lymphadenopathy, but it can also involve any part of the human body. lymphomatous involvement of muscles is a rare presentation and has been reported to occur in only 1.1% in non-hodgkin lymphoma. here we, present a 32 year-old iranian man with primary involvement of spleen, bone, bone marrow and muscle, mimicking soft tissue sarcoma; core ...

abstract objective the incidence of childhood cancer has been increasing nearly one percent per year for the past two decades. leukemia and lymphoma are the most common types of childhood cancers. this study assessed the relation between environmental factors (hydrocarbon, agricultural toxin, insecticide) and leukemia/lymphoma in children, which was evaluated by the frequency of the parents’ ha...

  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.

conclusions the association between viral hepatitis and nhl in the area of interest might provide some degree of explanation to this finding. our data confirm that due to epidemic infection of hcv in the area of naples, a high mortality for nhl persists, moreover the adoption of standard therapeutic protocols administered in full accordance with an evidence-based approach and current guidelines...

the most frequently studied association between a hepatitis virus and non hodgkin lymphoma (nhl) has been with hepatitis c virus (hcv). association with hepatitis b virus (hbv) is less studied. in this regard mixed cryoglobulinemia (mc) is more commonly associated with hcv than hbv. still rarer is cryofibrinogenemia in these patients.   lack of symptoms in addition its rarity delays the diagnos...
