Dural extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) is a rare entity without an associated recurrent genetic abnormality. Only one case has been described in a woman with history of breast carcinoma without a known genetic predisposition. Here, we report a case of a 56-year-old woman heterozygous for XRCC2 mutation with a history of Graves' disease and bilateral breast carcinomas, who was found to have a diffusely infiltrative extra-axial mass in the high parietal convexity with infiltration into the adjacent superior sagittal sinus. The morphologic, immunophenotypic, and molecular findings were diagnostic of MALT lymphoma. Staging bone marrow demonstrated involvement by the neoplasm. Although the study was limited to only the clinically significant laboratory evaluation, it may serve as an important addition to the current knowledge of the pathogenic potential of a loss of function mutation in this rarely reported cancer predisposition gene.

Marginal zone lymphomas represent approximately 10-12% of all B-cell lymphomas. Extranodal marginal zone lymphomas (EMZL) or mucosa-associated lymphoid tissue (MALT) lymphomas are the most common subt...
To date, this is the largest cohort study on extranodal marginal zone B-cell lymphoma (EMZL) of the ocular adnexa (OA). The aim of the study was to characterise the clinical features of OA-EMZL.
Primary endometrial marginal zone lymphoma (mucosa-associated lymphoid tissue [MALT] type) is a rare histological type of non-Hodgkin lymphoma (NHL); therefore, this disease is challenging to diagnosi...
We report a case of splenic marginal zone B-cell lymphoma discovered in a 73-year-old man with cold agglutinin disease. PET/CT revealed splenomegaly with focally intense uptake of F-FDG and diffusely ...
Short responses to immunochemotherapy predict for an inferior OS in follicular lymphoma. We set out to determine whether this is also the case in marginal zone lymphoma. A group of 139 marginal zone l...
Single-arm, phase II clinical trial of patients with Extranodal Marginal Zone Lymphoma (EMZL). It is planned to recruit 130 patients. Additional patients with Splenic Marginal Zone Lympho...
Marginal zone lymphoma, one of the indolent lymphoma, is believed to be incurable with chemotherapy. Thus the investigators need a novel agent for marginal zone lymphoma. Gemcitabine has b...
This is a single arm study to evaluate the efficacy, safety and tolerability of zanubrutinib (BGB-3111) in patients with relapsed/refractory marginal zone lymphoma (R/R MZL).
The purpose of this study is to assess the efficacy and safety of Ibrutinib in predominantly Asian patients with relapsed or refractory marginal zone lymphoma.
This prospective study will test the following hypotheses in patients with stage I-II low grade marginal zone (MZ) lymphoma: - Involved Field Radiotherapy will produce a complete respo...
Extranodal lymphoma of lymphoid tissue associated with mucosa that is in contact with exogenous antigens. Many of the sites of these lymphomas, such as the stomach, salivary gland, and thyroid, are normally devoid of lymphoid tissue. They acquire mucosa-associated lymphoid tissue (MALT) type as a result of an immunologically mediated disorder.
An extranodal neoplasm, usually possessing an NK-cell phenotype and associated with EPSTEIN-BARR VIRUS. These lymphomas exhibit a broad morphologic spectrum, frequent necrosis, angioinvasion, and most commonly present in the midfacial region, but also in other extranodal sites.
B-cell lymphoid tumors that occur in association with AIDS. Patients often present with an advanced stage of disease and highly malignant subtypes including BURKITT LYMPHOMA; IMMUNOBLASTIC LARGE-CELL LYMPHOMA; PRIMARY EFFUSION LYMPHOMA; and DIFFUSE, LARGE B-CELL, LYMPHOMA. The tumors are often disseminated in unusual extranodal sites and chromosomal abnormalities are frequently present. It is likely that polyclonal B-cell lymphoproliferation in AIDS is a complex result of EBV infection, HIV antigenic stimulation, and T-cell-dependent HIV activation.
An angiocentric and angiodestructive lymphoproliferative disorder primarily involving the lungs. It is caused by an Epstein-Barr virus-induced transformation of the B-cells, in a T-cell rich environment. Clinically and pathologically it resembles EXTRANODAL NK-T-CELL LYMPHOMA.
A secondary headache disorder attributed to low CEREBROSPINAL FLUID pressure caused by SPINAL PUNCTURE, usually after dural or lumbar puncture.
