Mucosa Associated Lymphoid Tissue (MALT) lymphoma, accounting for about 5% of non-Hodgkin’s lymphoma, arises in a number of epithelial tissues, mostly in the gastrointestinal tract, respiratory tract, ocular adnexa, thyroid and salivary glands. MALT lymphoma primarily arising from the kidney is extremely rare. Here we report a case that was admitted to our institution due to left hydronephrosis...

RATIONALE Mucosa-associated lymphoid tissue (MALT) lymphoma is an indolent B-cell lymphoma which occurs mainly in the organs having mucosal layer and owns a fairly good prognosis. To date, 7 cases of spinal primary MALT has been reported before. However, there is no consensus on the optimal adjuvant treatment modalities for primary spinal MALT. The aim of this study was to add a new case of MAL...

microRNAs (miRNAs) are small non-coding RNAs that can function as endogenous silencers of target genes and play critical roles in human malignancies. To investigate the molecular pathogenesis of gastric mucosa-associated lymphoid tissue (MALT) lymphoma, the miRNA expression profile was analyzed. miRNA microarray analysis with tissue specimens from gastric MALT lymphomas and surrounding non-tumo...

Although the GI tract is the most common site of low-grade B-cell lymphoma of mucosa-associated lymphoid tissue (MALT),1,2 duodenal MALT lymphoma is rare.3-10 The eradication of Helicobacter pylori is now considered the treatment of choice for gastric MALT lymphoma,11-14 yet therapeutic strategies for duodenal MALT lymphoma are still in dispute.3-10 This is a report of 2 cases of duodenal MALT ...

Mucosa-associated lymphoid tissue (MALT) lymphoma of the esophagus is a rare tumor [1–3] with varying presentations [4]. Only a few reports have described MALT lymphoma of the esophagus spanning the entire circumference and length of the esophagus [3]. Many of these cases were diagnosed surgically. Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is an established method of obtaini...

Non-Hodgkin's lymphoma very rarely involves the esophagus, occurring in less than 1% of patients with gastrointestinal lymphoma. A few cases of mucosa-associated lymphoid tissue (MALT) lymphoma of the esophagus have been reported in the English literature. To our knowledge, there has been no report of MALT lymphoma of the esophagus coexistent with bronchus-associated lymphoid tissue lymphoma (B...

Mucosa-Associated Lymphoid Tissue (MALT) lymphoma also referred to as extranodal marginal zone B-cell lymphoma, is rare in the oral soft tissue [1-8]. Primary MALT lymphomas are most commonly seen in the gastrointestinal tract [1,2,4]. Within the oral soft tissue, the salivary glands are the most affected with the parotid gland being the most common site [9] and the minor salivary glands being ...

We describe a 10 yr follow-up of a patient with a primary malignant non-Hodgkin's lymphoma of the lung, arising in mucosa-associated lymphoid tissue (MALT). Although the patient was not treated with chemotherapy or radiotherapy, no peripheral spread occurred, confirming that MALT-associated lymphomas apparently remain localized until late in the course of the disease.

In an area of lymphoma classification still being defined, marginal-zone lymphomas have distinctive immunohistochemical and cytogenetic features that distinguish them from mantle-cell and follicular lymphomas. There are three subtypes: the extranodal mucosa-associated lymphoid tissue (MALT) lymphomas, the nodal monocytoid B-cell (MBCL) lymphomas, and the splenic marginal-zone lymphomas. The MAL...

Expression of the C-type lectin-like receptor CD161 by human T cells is associated with type-17 responses, which play critical regulatory roles in immunity and inflammation at mucosal sites. However, the functions of CD161-expressing T cells in macaques, the pre-clinical model of several human diseases, remain unknown. This study examined the phenotypic and functional characteristics of CD161+ ...
