introduction: lymphomas as a group rank seventh as the most leading cause of death in cancers. stomach is the most common extra nodal site of primary lymphomas. on the other hand, new information demonstrates that malt lymphoma responds to helicobacter antibiotic therapy. we therefore decided to determine the frequency of distribution of helicobacter pylori infection in primary gastric lymphoma...

Primary cutaneous large B-cell lymphoma leg type is a rare andaggressive neoplasm as defined by the recently updated WorldHealth Organization - European Organization for Research andTreatment of Cancer. We report a case of an 80-year-old manwith multiple cutaneous lesions. Here, we review the availableliterature and summarize clinical features and management ofthis type of cutaneous B-cell lymp...

Intraocular cytokines are promising diagnostic biomarkers of vitreoretinal lymphoma. Here, we evaluate the utility of IL-10, IL-6 and IL-10/IL-6 for discriminating lymphoma from uveitis and report the effects of intraocular methotrexate and rituximab on aqueous cytokine levels in eyes with lymphoma. This is a retrospective case series including 10 patients with lymphoma and 7 patients with uvei...

  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.

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 ...

AIM To develop and assess a protocol for the treatment of intraocular lymphoma by intravitreal injection of methotrexate and thiotepa. METHODS A patient with intraocular non-Hodgkin's lymphoma which recurred after radiotherapy and repeated systemic chemotherapeutic regimens underwent repeated intravitreal injections of methotrexate and thiotepa. The patient was closely monitored by cytology, ...

BACKGROUND Primary intraocular lymphoma (PIOL) is a subset of primary central nervous system lymphoma (PCNSL) in which lymphoma cells initially invade the retina, vitreous, or optic nerve head, with or without concomitant CNS involvement. The incidence of this previously rare condition has increased dramatically. Given its nonspecific presentation and aggressive course, PIOL provides a diagnost...

INTRODUCTION Currently, the detection of pathogens or mutations associated with intraocular lymphomas heavily relies on prespecified, directed PCRs. With metagenomic deep sequencing (MDS), an unbiased high-throughput sequencing approach, all pathogens as well as all mutations present in the host's genome can be detected in the same small amount of ocular fluid. METHODS In this cross-sectional...
