BACKGROUND Mucosa-associated lymphoid tissue lymphoma (MALT lymphoma) of the lung is a relatively rare disease. As little is known about the natural clinical course if left untreated, all patients undergoing a watch-and-wait policy at our institution were investigated. PATIENTS AND METHODS A retrospective analysis identified a total of 11 patients with MALT lymphoma of the lung who did not un...
Chromosomal translocations involving the MALT1 gene are hallmarks of mucosa-associated lymphoid tissue (MALT) lymphoma. To date, targeting these translocations to mouse B cells has failed to reproduce human disease. Here, we induced MALT1 expression in mouse Sca1(+)Lin(-) hematopoietic stem/progenitor cells, which showed NF-κB activation and early lymphoid priming, being selectively skewed towa...
PURPOSE The aim of this 10-year retrospective study was to investigate prognostic clinical and laboratory factors significant for the outcome of patients with mucosa associated lymphoid tissue (MALT) lymphoma. METHODS The study involved 87 patients diagnosed with MALT lymphoma: 37 (42.5%) with gastrointestinal (GI) and 50 (57.5%) with non-GI localization. The following pretreatment laboratory...
Marginal zone B-cell lymphoma (MZBCL) including extranodal mucosa-associated lymphoid tissue (MALT)-type lymphoma, nodal, and splenic MZBCL represents a distinct subtype of B-non-Hodgkin's lymphoma. Recently, important progress in the elucidation of the genetic mechanisms underlying the pathogenesis and disease progression of these lymphomas has been made. The API2 gene, an inhibitor of apoptos...
Background. Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) is a well-characterized entity that may share clinical and morphological findings with other low-grade non-Hodgkin's lymphomas. Dissemination of MALT-type lymphoma to bone marrow and peripheral blood simultaneously with the presence of T-large granular cell leukemia (T-LGL) has rarely been reported. Case P...
AIM Extranodal mucosa-associated lymphoid tissue (MALT) arises a number of epithelial tissues, including the stomach, salivary gland, lung, small bowel, and elsewhere. Here we present a male patient with an uncommon site of extranodal MALT such as a pelvic mass diagnosed after a long period of evaluation, which initially presented with an incidental pulmonary nodule. METHOD We report a 60 yea...
BACKGROUND AND OBJECTIVES Aberrant promoter methylation targets CpG islands causing gene silencing. We explored aberrant promoter methylation of genes potentially involved in B-cell malignancies and encoding proteins implicated in DNA repair (O6-methylguanine-DNA methyltransferase, MGMT), detoxification of environmental xenobiotics (glutathione S-transferase P1, GSTP1), apoptosis regulation (de...
Purpose: To elucidate MRI features of primary hepatic mucosa-associated lymphoid tissue (MALT) lymphoma, particularly, the “speckled enhancement” on gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced MRI.
