Primary extranodal lymphomas are relatively rare non-Hodgkin lymphoma presentations with either no or only "minor" nodal involvement along with a clinically "dominant" extranodal component, to which primary treatment must often be directed. Clinical presentations depend largely on the localization and are similar to those of other malignancies affecting ...

Our patient was an 86-year-old man who had worked as a lathe operator for 40 years. He had no history of tuberculosis, pyothorax, or autoimmune disease. He had not been exposed to asbestos. He was asymptomatic, but an imaging study showed gradually increasing pleural plaques. A biopsy specimen of a pleural lesion showed sclerosis of the pleura and diffuse infiltration of small- to medium-sized B ...
Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is related to Helicobacter pylori infection.

Chromosomal translocations between loci encoding MALT1 and c-IAP2 are common in MALT lymphomas. The resulting fusion proteins lack the c-IAP2 RING domain, the region responsible for its ubiquitin protein ligase (E3) activity.

The aim of this study was to investigate the Lewis antigen expression in Helicobacter pylori gastric MALT lymphoma associated strains in comparison to chronic gastritis only strains. Forty MALT strains (19 cagPAI (?) and 21 cagPAI (+)) and 39 cagPAI frequency-matched gastritis strains (17 cagPAI (?) and 22 cagPAI (+)) were included in ...
Background/AimsEndoscopic ultrasound (EUS) plays a crucial role in the assessment and treatment of low-grade gastric mucosa-associated lymphoid tissue (MALT) lymphoma; however, interobserver variation, inadequate accuracy in judging the depth of tumor invasion, and histological heterogeneity of the tumor can limit its role. Thus, we have assessed the role ...
Helicobacter pylori is predominantly involved in the etiology of digestive diseases. The aim of our study is to determine the relationship of cagA frequency with less investigated gastroduodenal disorders such as MALT (mucosal associated lymphoid tissue) lymphoma and gastric cancer. One hundred-twenty eight H. pylori-positive patients including: gastritis ...

A 85-year-old woman presented with macroscopic hematuria and miction pain. Cystoscopy revealed a wide-based submucosal mass, and biopsied specimens of the mass showed a B-cell lymphoma of the MALT type. Computed tomography (CT) showed a 7.5 x 3.0 cm solitary mass lesion situated from the anterior wall to the right lateral bladder wall, and magnetic ...
Marginal zone B-cell lymphoma (MZL) is the second most common subtype of non-Hodgkin's lymphoma in Korea (17.3%). Mucosa-associated lymphoid tissue (MALT) can develop in almost any organ as a result of exposure to a persistent stimulus, such as chronic infection or certain autoimmune processes. Under conditions of prolonged lymphoid ...
Primary presentation of intradural non-Hodgkin lymphoma is rare. Recently, B-cell lymphomas of mucosa-associated lymphoid tissue (MALT) have been recognized as an important pathologic subtype. When MALT lymphomas present in the central nervous system (CNS), they are distinguishable from primary ...

Studies from different countries showed variations of genetic changes and association with Chlamydia psittaci in ocular adnexal mucosa-associated lymphoid tissue (MALT) lymphoma. A total of 38 ocular adnexal MALT lymphoma cases from Northern China were studied. Genetic abnormalities were investigated in 28 cases by ...
The normal human stomach is devoid of any organized lymphatic tissue. Acquisition of mucosa-associated lymphatoid tissue (MALT) in the stomach is considered to be a direct consequence of chronic infection with Helicobacter pylori. Thus, MALT appears to be part of the host defense against the pathogen H. pylori. Consequently, lymphomas ...
We describe a case of bilateral conjunctival mucosa-associated lymphoid tissue (MALT) lymphoma in a 14-year-old female treated with intralesional interferon-?. Interferon-?-2b was injected three times a week for 6 weeks, then once weekly for 12 weeks. Marked tumor reduction was observed by week 5 of treatment, with complete resolution by week 8. There was ...
We herein present a quite atypical case of primary gastrointestinal mucosa-associated lymphoid tissue (MALT) lymphoma in the transverse colon.

We report a case of low-grade B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) involving the left kidney and simultaneous onset of a monoclonal gammopathy IgM kappa. No predisposing local inflammatory condition was identified. Following left nephrectomy, the renal specimen showed the centrocyte like cells and lymphoid cells in the ...
Abstract Gastric Helicobacter pylori (HP) positive extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) develops during chronic antigenic stimulation with specific T-cell help. Chemotherapy that both acts on the malignant B-cellsand on T-cells in the microenvironment, i.e. nucleoside analogs, might therefore be an attractive ...
Normal gastric mucosa is devoid of lymphoid cells. Any increase of lymphocytes suggests chronic inflammation. Infection with Helicobacter pylori (Hp) is the major cause for nonautoimmune chronic gastritis and induces a mixed cellular response resulting in an acquired lymphoid tissue, or MALT (mucosa-associated lymphoid tissue). Hp has also been implicated in the genesis of ...
BackgroundMantle cell lymphoma is a lymphoid entity characterized by adenopathy, blood and bone marrow involment which only recurrent mucosal localisation is the lymphomatoid polyposis. Few other mucosal infiltrations have been already reported.ResultsWe report here the first case of a unique tracheal localisation of mantle cell lymphoma at presentation of ...
OBJECTIVE: We evaluated the therapeutic efficacy of radical gastrectomy for primary B-cell lymphoma of the stomach and attempted to identify patients who could be adequately treated with surgery alone. SUMMARY BACKGROUND DATA: Several recent gastric lymphoma reports have discussed the therapeutic benefits of various treatment strategies for stage IE and ...
Abstract We investigated six new cases of primary thymic extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) to further characterize the clinicopathological and genetic features. The male to female ratio was 1:1. One female patient had suffered from systemic lupus erythematosus. Another female patient was diagnosed with ...
Gastric low-grade mucosa-associated lymphoid tissue (low-grade MALT) lymphomas has been associated with Helicobacter pylori (H. pylori) infection. Although infiltrating T cells with specificity for H. pylori are known to stimulate the development of MALT lymphomas, the effect of H. pylori eradication on rearranged ...
Although lymphomas have been reported in patients with acquired immunodeficiency syndrome, it has rarely been reported from the Indian subcontinent. We present three human immunodeficiency virus-infected patients (two adults and one child) who had non-Hodgkin�s lymphoma - plasmablastic variety, Hodgkin�s lymphoma - nodular ...
t(11;18)(q21;q21) is a characteristic as well as the most frequent chromosomal translocation in mucosa-associated lymphoid tissue (MALT) type lymphoma, and this translocation results in a fusion transcript, API2-MALT1. Although API2-MALT1 has been shown to enforce activation of NF-{kappa}B signaling, the ...
BackgroundTreatment of primary gastric diffuse large B-cell lymphoma is still controversial. The treatment of localized disease was based on surgery alone, or followed by chemotherapy and/or radiotherapy. High-grade gastric lymphomas are generally believed to be Helicobacter pylori (HP)-independent growing tumors. However a few cases of regression of ...

An asymptomatic 77-year-old woman was referred in 2000 because multiple nodular shadows were found on chest X-ray films on a medical checkup. Chest computed tomography (CT) showed bilateral multiple ground-glass opacities and ill-defined nodules. A transbronchial lung biopsy was performed via bronchoscopy, but the specimens did not yield any specific findings. She was then monitored without ...
