Primary mucosa-associated lymphoid tissue (MALT) lymphoma of the lacrimal drainage system in two pediatric patients.

Eur J Ophthalmol 2019 Mar 12:1120672119837085. Epub 2019 Mar 12.

2 Department of Ophthalmology, Gazi University Medical School, Ankara, Turkey.

Primary non-Hodgkin lymphoma (NHL) of lacrimal drainage system (LDS) is quite rare in children, but it is important to expedite early diagnosis in an effort to alter possible life-threatening disease since they are usually misdiagnosed as chronic dacryocystitis. In the literature, there are few examples of tumors of LDS in children. The authors herein report two pediatric cases of extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) originating from lacrimal sac in an attempt to increase the knowledge about the clinical course of NHL of LDS.

Pre-Therapeutic Total Lesion Glycolysis on [F]FDG-PET Enables Prognostication of 2-Year Progression-Free Survival in MALT Lymphoma Patients Treated with CD20-Antibody-Based Immunotherapy.

Mol Imaging Biol 2019 Mar 7. Epub 2019 Mar 7.

Department of Medicine I, Medical University of Vienna, Vienna, Austria.

Purpose: Standardized uptake values (SUV), total metabolic tumor volumes (TMTV), and total lesion glycolysis (TLG) based on positron emission tomography with 2-deoxy-2-[F]fluoro-D-glucose ([F]FDG/positron emission tomography (PET) are established outcome predictors in FDG-avid lymphomas. We therefore investigated whether these biomarkers also have prognostic value in extranodal marginal zone B cell lymphoma of the mucosa-associated lymphoid tissue (MALT lymphoma), with a focus on patients treated with anti-CD20 antibody-based immunotherapy.

Procedures: Pre-therapeutic [F]FDG/PET scans of 61 treatment-naïve MALT lymphoma patients, including 35 scheduled for anti-CD20 antibody-based immunotherapy, were included in this retrospective study. Read More

Lymphomas complicating primary Sjögren's syndrome: from autoimmunity to lymphoma.

Rheumatology (Oxford) 2019 Mar 5. Epub 2019 Mar 5.

Department of Rheumatology, Université Paris-Sud, AP-HP, Hôpitaux Universitaires Paris-Sud, Centre for Immunology of Viral Infections and Autoimmune Diseases, INSERM UMR1184, Le Kremlin Bicêtre, France.

Lymphoma development is the most serious complication of SS and the main factor impacting on mortality rate in patients with this condition. Lymphomas in SS are most commonly extranodal non-Hodgkin B-cell lymphomas of the mucosa-associated lymphoid tissue and frequently arise in salivary glands that are the target of a chronic inflammatory autoimmune process. Extensive work on lymphomagenesis in SS has established that the progression towards B-cell lymphoma is a multistep process related to local chronic antigenic stimulation of B cells. Read More

Front-line management of indolent non-Hodgkin lymphoma in Australia. Part 2: mantle cell lymphoma and marginal zone lymphoma.

Intern Med J 2019 Feb 28. Epub 2019 Feb 28.

Division of Cancer Services, Clinical Haematology, Princess Alexandra Hospital, Brisbane, QLD.

Mantle cell lymphoma (MCL) and the marginal zone lymphoma (MZL) subtypes (nodal MZL, extra-nodal MZL of mucosa-associated lymphoid tissue (MALT lymphoma) and splenic MZL) are uncommon lymphoma subtypes, accounting for less than 5-10% of all non-Hodgkin lymphoma. The evidence base for therapy is therefore limited and enrolment into clinical trials is preferred. Outcomes for patients with MCL have been steadily improving mainly due to the adoption of more intense strategies in younger patients, the use of rituximab maintenance and the recent introduction of bendamustine in older patients.

Helicobacter pylori and nutrition: a bidirectional communication.

Minerva Gastroenterol Dietol 2019 Feb 12. Epub 2019 Feb 12.

Unit of Dietetics and Clinical Nutrition, Città della Salute e della Scienza, Turin, Italy.

Helicobacter pylori (HP) is a gram negative flagellated pathogen acid-resistant bacterium; it belongs to the order Campylobacterales that is wide spread all over the world, infecting more than 50% of the world population. HP infection is etiologically associated with non-atrophic and atrophic gastritis, peptic ulcer and with 3 to 6-fold increased relative risk for developing gastric adenocarcinoma and mucosa-associated lymphoid tissue (MA LT) lymphoma. For this reason HP is recognized by the World Health Organization as a Class I human carcinogen. Read More

Pulmonary Nodular Lymphoid Hyperplasia.

Arch Pathol Lab Med 2019 Feb 6. Epub 2019 Feb 6.

and the Department of Pathology, University of Texas Southwestern Biocenter, Dallas (Dr Rosado).

Pulmonary nodular lymphoid hyperplasia is an uncommon reactive lymphoproliferative disorder that presents as an asymptomatic lung mass. The histopathologic diagnosis of pulmonary nodular lymphoid hyperplasia may be challenging because of its morphologic overlap with other diseases, such as extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue and immunoglobulin G4-related sclerosing disease. Despite the similarities, there are distinctive morphologic and phenotypic features that allow for the correct diagnosis in the majority of cases. Read More

Spontaneous Remission of Diffuse Large B Cell Lymphoma in the Stomach and the Continuation of Remission for 10 Years.

Case Rep Gastroenterol 2018 Sep-Dec;12(3):699-703. Epub 2018 Nov 28.

Department of Pathology, University of Toyama, Toyama, Japan.

According to the literature, spontaneous remission of aggressive lymphomas is extremely rare; gastric non-Hodgkin lymphomas, such as mucosa-associated lymphoid tissue lymphomas, often regress due to treatment or no progression, even in a watch-and-wait strategy. Although spontaneous remission of diffuse large B cell lymphomas in the stomach was very rarely reported, the follow-up periods of the cases of spontaneous remission are within 2 years and most cases are likely to relapse after the first remission. Here, we report that a diffuse large B cell lymphoma in the stomach showed spontaneous remission within 2 months after the initial diagnosis and the remission is still continuing for 10 years without any specific treatments against this aggressive lymphoma.

The fish immune system is extremely complex and has considerable adaptive potential. In Osteichthyes, the system is formed by lymphopoietic organs which are important for the differentiation and maturation of the immune system cells. These organs include the anterior kidney (phronephros), the thymus, the spleen, the posterior kidney (mesonephros), and mucosa-associated lymphoid tissues (MALT). Read More

Mucosa-associated lymphoid tissue lymphoma with metachronous involvement of the palpebral conjunctiva and bronchus: A case report.

Respir Med Case Rep 2019 8;26:101-104. Epub 2018 Dec 8.

Department of Pulmonary Medicine, Seirei Hamamatsu General Hospital, 430-0906 2-12-12, Sumiyoshi Naka-ku, Hamamatsu-city, Shizuoka, Japan.

A 61-year-old woman with a history of palpebral conjunctival mucosa-associated lymphoid tissue (MALT) lymphoma, treated with rituximab, was referred to the authors' hospital after follow-up positron emission tomography/computed tomography revealed F-fluoro-2-deoxy-d-glucose uptake in a tumor located in the left main bronchus. The diagnosis of MALT lymphoma was made by pathological and immunohistochemical findings homologous to previous palpebral conjunctival lesion via bronchoscopic biopsy. The disease was controlled with rituximab, cyclophosphamide, oncovin, and prednisolone (i. Read More

Department of Radiation Oncology, The University of Texas MD Anderson Cancer Center, Houston, TX, USA,

Gastrointestinal stromal tumor (GIST) is an uncommon mesenchymal tumor, and has been shown to be associated with synchronous or metachronous second malignancies. Rare cases of coincident GIST and non-Hodgkin lymphomas (NHL) have been reported previously. Here, we report two cases of GIST and coincident primary breast lymphoma, an uncommon subtype of extranodal NHL. Read More

The Epstein-Barr virus induces the expression of the LPAM-1 integrin in B-cells and .

J Virol 2018 Dec 12. Epub 2018 Dec 12.

German Cancer Research Centre (DKFZ) Unit F100, Heidelberg, Germany

The Epstein-Barr virus (EBV) infects the oropharynx but surprisingly frequently induces B-cell proliferations in the gut of immunosuppressed individuals. We found that EBV infection induces the expression of the LPAM-1 integrin on tonsillar B cells and increases it on peripheral blood cells. Similarly, LPAM-1 was induced in the tonsils of patients undergoing primary infectious mononucleosis. Read More

Determination of Autoantibodies to Salivary Gland Antigens.

Methods Mol Biol 2019 ;1901:103-112

UCLA School of Dentistry, Los Angeles, CA, USA.

Primary Sjögren's syndrome (pSS) is a systemic autoimmune disease marked by dry mouth/dry eye symptoms as a result of the destruction of the salivary and lacrimal glands. Patients with pSS may be at risk for the development of mucosa-associated lymphoid tissue (MALT) lymphoma. Testing of autoantibodies in the oral fluid of patients with pSS or MALT lymphoma using immunoassays may lead to a simple and noninvasive clinical tool for diagnostic or prognostic applications.

Electronic address:

Selection for prolificacy in modern pig farming has resulted in increasing litter sizes. Since rearing large litters is challenging, artificial rearing of piglets with a milk replacer is an alternative strategy. It is hypothesized that the development of the piglets' mucosa-associated lymphoid tissues (MALT) is affected by these artificial conditions. Read More

Mepazine Inhibits RANK-Induced Osteoclastogenesis Independent of Its MALT1 Inhibitory Function.

Molecules 2018 Nov 30;23(12). Epub 2018 Nov 30.

Unit of Molecular Signal Transduction in Inflammation, VIB-UGent Center for Inflammation Research, VIB, 9052 Ghent, Belgium.

Mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT1) is an intracellular cysteine protease (paracaspase) that plays an integral role in innate and adaptive immunity. The phenothiazine mepazine has been shown to inhibit the proteolytic activity of MALT1 and is frequently used to study its biological role. MALT1 has recently been suggested as a therapeutic target in rheumatoid arthritis. Read More
