BACKGROUND: Primary gastrointestinal (GI) lymphomas (GIL) are uncommon diseases that can involve the whole GI tract. Considerable variation exists in the literature with respect to incidence of the various histological subtypes and sites of involvement. This study was undertaken to establish the anatomic distribution, histological subtypes and sites of GI lymphomas of patients from Western Algeria. METHODS: The case records of 58 consecutive patients with GIL diagnosed at the Pathologies Departments of Algerian west region (the Military Hospital of Oran city and the Central University Hospital of Sidi Bel Abbes city) from January 2006 to December 2013 were retrospectively evaluated for epidemiology and histopathology report...

This study aimed to assess the long-term outcomes of radiotherapy in patients with localized gastric mucosa-associated lymphoid tissue (MALT) lymphoma. Twenty-seven patients with Stage I gastric MALT lymphoma were treated with radiotherapy from 1999 to 2010. The median age was 65 years (range: 31-84). Fifteen patients were Helicobacter pylori-negative. Thirteen patients were treated with definitive radiotherapy alone. The other 14 patients who had refractory or residual disease following a prior treatment received salvage radiotherapy...

A 66-year-old man with recurrent stroke within a short period of time was referred to our department from the neurology department to rule out any malignancy. An endoscopic examination revealed a white depressed lesion in the body of the stomach, and computed tomography revealed a high-density area in the mesentery around the stomach. A mucosa-associated lymphoid tissue (MALT) lymphoma was detected from both the stomach biopsy and resected mesenteric specimen. Systemic chemotherapy was administered for the MALT lymphoma (Lugano classification stage IV)...

BACKGROUND: Transbronchial biopsy (TBB) using radial endobronchial ultrasound with a guide sheath (REBUS-GS) has improved the diagnosis of peripheral pulmonary lesions (PPLs). Because of the high cost of the GS, REBUS with distance (REBUS-D) has certain advantages. The aim of this study was to compare the diagnostic yield of the REBUS-GS and REBUS-D by thin bronchoscopy for PPLs. METHODS: Patients with PPLs were enrolled in a prospective randomized crossover study from August 2014 and July 2015...

Primary esophageal lymphoma is an extremely rare disease. We report a 76-year-old woman with esophageal lymphoma who achieved remission after Helicobacter pylori (HP) eradication. Esophagogastroduodenoscopy (EGD) revealed a mass in the lower esophagus, and she was diagnosed with stage IE mucosa-associated lymphoid tissue (MALT) lymphoma. She rejected any anti-lymphoma treatment except for HP eradication. Follow-up EGD demonstrated the disappearance of the esophageal MALT lymphoma 2 months after HP eradication, and she remained in remission for more than 3 years...

Dermal filler injection has been one of the most evolving areas of interest in the field of esthetic plastic surgery. This procedure is sometimes preferred to surgery due to shorter procedure and patient recovery times, and because it is suitable for a wide range of applications. Dermal filler injection is considered to be relatively safe, but various late complications such as infection and foreign body granuloma sometimes occur. Postprocedure development of lymphoma also occurs, but is extremely rare. The authors diagnosed extranodal marginal zone B-cell lymphoma of the mucosa associated lymphoid tissue that developed after a filler injection procedure was performed on a patient's face...

Mucosa-associated lymphatic tissue (MALT) lymphoma of the breast is an extremely rare disease; its pathogenesis is not clear because of the rarity of disease, and the best diagnostic method has yet to be established. The metabolic behavior of this lymphoma is not still clear because only a few case reports are present in literature describing the possible role of fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) in this field. This report presents 4 cases of women with histologically proven breast MALT lymphoma who underwent 7 18F-FDG PET/CT throughout the course of disease...

PURPOSE: Primary rectal lymphoma (PRL) is the third most common cause of rectal cancer following adenocarcinoma (90-95 %) and carcinoid (5 %). The most common variant of PRL is the mucosa-associated lymphoid tissue (MALT) type. To date, no study has been able to recommend an optimal treatment algorithm for this rare disease. The aim of our study was to review the English literature on primary rectal MALT lymphoma. METHODS: A review of the English literature was conducted to identify articles describing the MALT variant of PRL...

Russell bodies gastritis is a very rare disease, with few cases reported in literature, and characterized by the finding of plasma cells with eosinophilic intracytoplasmic inclusions in the gastric mucosa, called Mott cells. Although it has been partnered since its first description to Helicobacter pylori infection, it is important to considered differential diagnoses such as lymphoplasmacytic lymphoma, mucosa-associated lymphoid tissue (MALT) lymphoma, plasmacytoma and signet ring cell carcinom. In this case report, we address a patient with histologic confirmation and her follow up...

IgG4-related disease is a systemic disorder involving a spectrum of multiple indications, and various histopathological features are shared among different IgG4-related disease subtypes, which challenge diagnosis, although certain syndromes have organ-specific involvement. Among them, Mikulicz's disease affecting the salivary and lacrimal glands, distinguished by often elevated levels of serum IgG4, infiltration of IgG4(+) plasma cells into target tissues, and diffuse swelling, mass formation, or fibrosis of affected organs...

BACKGROUND: Approximately 95% of tumors occurring within the internal auditory canal (IAC) are vestibular schwannomas (VSs). Many undergo stereotactic radiation without definitive tissue diagnosis. Rare IAC tumors are not all radiosensitive and are poorly described. METHODS: Between 1992 and 2015, 289 consecutive patients with IAC lesions operated on were retrospectively reviewed. RESULTS: Fifteen patients (5.2%) (16 operations) had unusual histological findings, including non-vestibular schwannomas (two facial schwannomas, two cochlear schwannomas, two intermedius schwannomas), three meningiomas, three cavernous hemangiomas, a mucosa associated lymphoid tissue (MALT) lymphoma, an arachnoid cyst, and a lipochoristoma...

Helicobacter pylori infection is associated with chronic gastritis, peptic ulcers, gastric cancer and mucosa-associated lymphoid tissue lymphoma. The limitations of current therapies for Helicobacter pylori infection include poor compliance and antibiotic resistance. Therefore, an effective anti-H. pylori vaccine would be an alternative or complement to antibiotic treatment. Urease B (UreB) is considered an ideal vaccine antigen against H. pylori infection. In this study, cholera toxin B subunit (CTB), a mucosal adjuvant, was used to enhance the immunogenicity of novel Bacillus subtilis spores vaccine that express CTB-UreB along with the B...

Helicobacter pylori is the most frequent and persistent bacterial infection worldwide, and a risk factor for active gastritis, peptic ulcers, mucosa-associated lymphoid tissue lymphoma, and gastric cancer. Although combined antibiotics treatment is effective cases of antibiotic resistance are reported at an alarming rate. The H. pylori urease enzyme is essential for the bacteria establishment in the gastric mucosa, resulting urease inhibitors being sought after as effective and specific anti- H. pylori treatment...

In hematological malignancies complex interactions exist between the immune system, microorganisms and malignant cells. On one hand, microorganisms can induce cancer, as illustrated by specific infection-induced lymphoproliferative diseases such as Helicobacter pylori-associated gastric mucosa-associated lymphoid tissue lymphoma. On the other hand, malignant cells create an immunosuppressive environment for their own benefit, but this also results in an increased risk of infections. Disrupted innate immunity contributes to the neoplastic transformation of blood cells by several mechanisms, including the uncontrolled clearance of microbial and autoantigens resulting in chronic immune stimulation and proliferation, chronic inflammation, and defective immune surveillance and anti-cancer immunity...

OBJECTIVE: Helicobacter pylori is a bacterial pathogen associated with chronic gastritis, peptic ulcer disease, gastric adenocarcinoma, and gastric mucosa associated lymphoid tissue lymphoma. Current treatment guidelines support a 7- to 14-day, triple-drug protocol consisting of a proton-pump inhibitor (PPI), clarithromycin, and either amoxicillin or an imidazole. The initial eradication rates for this regimen were 80 to 90%. Nevertheless its effectiveness has declined as the antibiotic resistance to clarithromycin and metronidazole has emerged...

BACKGROUND: Mouse infection studies have shown that interferon-γ (IFN-γ), a T helper 1 (Th1) cytokine, is required for the development of severe pathology induced by chronic Helicobacter infection. This finding is largely based on studies performed using mice that have polarised Th1 responses i.e. C57BL/6 animals. The current work aims to investigate the role of IFN-γ in Helicobacter-induced inflammation in BALB/c mice which have Th2-polarised immune responses. RESULTS: At 7 months post-infection with Helicobacter felis, IFN-γ deficiency in BALB/c mice had no significant effect on H...

INTRODUCTION: Helicobacter pylori is a Gram-negative, microaerophilic bacterium that colonizes human gastric mucosa. Gastric ulcer, duodenal ulcer, chronic atrophic gastritis, mucosa-associated lymphoid tissue lymphoma, and stomach adenocarcinoma are associated with H. pylori as the etiological agent. Cytotoxin-associated gene A (cagA), which is one of the most important virulence factors of H. pylori, encodes a 120-145 kDa protein. The prevalence of cagA genes shows differences in H...
