Primary breast mucosa-associated lymphoid tissue (MALT) lymphomas are uncommon and restricted diagnostic criteria should be used to exclude breast involvement by systemic lymphomas. The molecular pathogenesis of primary breast MALT lymphomas is not clear because of the rarity of the disease. Generally the molecular studies of MALT lymphoma in extr...

Malt is a preferred base for fermentations that produce beer or whisky. Barley for malt is grown under diverse environments in different geographical locations. Malt provides an ecological niche for a varied range of microorganisms with both positive and negative effects on its quality for brewing. Little information exists in the literature on the microbial community structure of Australian ma...

We describe marginal zone lymphoma of the mucosa-associated lymphoid tissue (MALT) and especially MALT lymphoma occurring in the conjunctiva. Tumors of the conjunctiva and cornea are grouped into two major categories of congenital and acquired lesions. Lymphoid tumors of the conjunctiva are acquired tumors and can occur as an isolated lesion or can be a manifestation of systemic lymphoma. Prima...

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 ...

The genes of the Escherichia coli maltose regulon are controlled by MalT, the specific transcriptional activator which, together with the inducer maltotriose and ATP, is essential for mal gene transcription. Network regulation in this system affects the function of MalT and occurs on two levels. The first concerns the expression of malT. It has long been known that malT is under catabolite repr...

Mucosa-associated lymphoid tissue (MALT) lymphoma is the third most common non-Hodgkin lymphoma, and it is strongly associated with helicobacter pylori infection of the stomach. MALT lymphoma of the lacrimal gland usually presents as a localized disease process in extranodal tissues. The treatment options of MALT lymphoma of the lacrimal gland chiefly include radiation of the tumor, chemotherap...

We are reporting a case of a 62-year-old African American woman with a history of gastric MALT lymphoma successfully treated with radiation who presented with a laryngeal MALT lymphoma 4 years after her original diagnosis. She received definitive radiation with a complete response. The case presented is unique for the rare presentation of a MALT lymphoma in the larynx, especially in light of th...

Mucosa-associated lymphoid tissue (MALT) lymphoma is an extranodal indolent lymphoma with histopatholigic features similar to those of marginal zone B-cell lymphomas. Primary breast MALT lymphomas were first described by Lamovec and Jancar as a low-grade B-cell lymphoma in 1987. Herein, a case is presented of a patient with primary MALT lymphoma of the breast. Issues in diagnosis and breast-con...

Most colonic multiple mucosa-associated lymphoid tissue (MALT) lymphomas are confirmed with a histologic and immunohistochemical staining of the mucosal biopsy specimen obtained during colonoscopic examinations. Endoscopically, colonic MALT lymphomas frequently appear as protruding and/or ulcerative lesions, and there are not so many reports of colonic MALT lymphoma as compared to the frequent ...

PATIENT Female, 91 FINAL DIAGNOSIS: Low-grade gastric MALT lymphoma Symptoms: Recurrent epigastric and right upper quadrant dyscomfort Medication: Rituximab Clinical Procedure: esophagogastroduodenoscopy • gastric biopsy Specialty: Gastroenterology. OBJECTIVE Unusual or unexpected effect of treatment. BACKGROUND Mucosa associated lymphoid tissue (MALT) lymphoma can occur in any extranodal o...
