This consensus report of the EGILS (European Gastro-Intestinal Lymphoma Study) group includes recommendations on the management of gastric extranodal marginal zone B-cell lymphoma of MALT. They are based on data from the literature and on intensive discussions and votings of the experts during their annual meetings.

Typically, when one authors a commentary piece, a good template to follow is to start with some background material, review the major findings of the paper in question, and then focus on areas of controversy and unanswered questions. After reviewing the comprehensive article by Traverse-Glehen et al, we admittedly struggled to follow this template. Why is that? For starters, their review is so ...

We describe a rare case of extranodal marginal zone/low-grade B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) combined with areas of well-differentiated adenocarcinoma. In addition, the MALT lymphoma was synchronously systemic, with involvement of the lung, stomach and duodenum.

The aim of the present study was to determine the optimal dose and optimal target volume for marginal zone lymphoma of the ocular adnexa. Between January, 2008 and December, 2013, 40 patients with histologically proven primary marginal zone lymphoma of the ocular adnexa who underwent radiotherapy at the Tokyo Medical University were evaluated. The prescribed dose was 30 Gy in 15 fractions to th...

BACKGROUND Low-grade B-cell lymphomas are a very heterogeneous group of tumors, whose differential diagnosis is frequently compromised by the lack of specific cytogenetic or molecular features. Our objective was to search for genomic features that allow a better molecular identification of the different types of lymphoma studied. DESIGN AND METHODS We selected a panel of 87 low-grade B-cell l...

Acquired angioedema (AAE) due to C1-inhibitor (C1INH) deficiency is rare. Treatment options for acute attacks are variable and used off-label. Successful treatment of the associated lymphoma with rituximab seems to prevent acute attacks in subjects with AAE. The aim of this study was to describe AAE manifestations, its associated diseases, and patients' responses to treatments in a representati...

Histologic transformation (HT) refers to a biologic event leading to the development of a high-grade, aggressive non-Hodgkin lymphoma in patientswith anunderlying follicular lymphoma (FL). Transformation to diffuse large B-cell lymphoma (DLBCL) or Burkitt lymphoma is also known to take place in other subtypes of indolent lymphoma such as marginal zone lymphoma, lymphoplasmacytic lymphoma, small...

UNLABELLED PET/CT with (18)F-FDG is an important noninvasive diagnostic tool for management of patients with lymphoma, and its use may surpass current guideline recommendations. The aim of the present study is to enlarge the growing body of evidence concerning (18)F-FDG avidity of lymphoma to provide a basis for future guidelines. METHODS The reports from (18)F-FDG PET/CT studies performed in...

Regression of an HCV-associated disseminated marginal zone lymphoma under IFN-free antiviral treatment Hepatitis C virus (HCV) is prevalent in B-cell–associated lymphomas, including marginal zone and diffuse large B-cell lymphomas. 1 A step-wise model of lymphomagenesis induced by chronic antigenic stimulation and/or a direct pro-oncogenic effect of intracellular HCV proteins is a possible mech...

A 73-year-old Japanese man with synchronous follicular lymphoma and adenocarcinoma of the stomach underwent curative surgical resection. The follicular lymphoma lesion was preoperatively diagnosed as extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) according to biopsy samples. However, postoperative pathological evaluations revealed components of CD10-posit...
