Mucosa-Associated Lymphoid Tissues

2017
The mucosal immune system is organized as a complex of two large pools of single immune-competent cells within the epithelium (lymphocytes: IEL) and lamina propria (lymphocytes: LPL) of the mucosa; the lymph nodes draining the mucosa; and the more or less organized lymphoid tissues associated with the mucosal epithelium.

Malignant lymphoma of mucosa‐associated lymphoid tissue

Histopathology, 1987
Lymphomas of the gastrointestinal tract, salivary glands, lung and thyroid are grouped together as tumours arising in mucosa‐associated lymphoid tissue. The great majority of them are of B‐cell origin but distinctive T‐cell lymphomas are also recognized in the gastrointestinal tract.

Mucosa‐associated lymphoid tissue (MALT) Iymphoma

Pathology International, 1995
SUMMARYIsaacson et al. defined MALT lymphoma as a neoplasm that mimics MALT lymphocytes, which are normally present in the small intestine. However, there are various problems with this definition of MALT lymphoma. First, the incidence of MALT lymphoma is not high in sites where MALT lymphocytes are normally present.

Nongastric Mucosa-Associated Lymphoid Tissue Lymphomas

Clinical Lymphoma, 2003
Nongastric mucosa-associated lymphoid tissue (MALT)-derived lymphomas arise from various extranodal locations and are usually related to a particular pathogenesis with a possible external (environmental or autoimmune) event inducing the disease. We reviewed 165 patients with nongastric MALT lymphoma among the 243 patients with MALT lymphoma in our ...

Morphology of mucosa‐associated lymphoid tissue in odontocetes

Microscopy Research and Technique, 2016
AbstractThis study describes the mucosa‐associated lymphoid tissue (MALT) in odontocetes from the Brazilian coast and freshwater systems. Seven species were evaluated and tissue samples were analyzed by light, scanning and transmission electron microscopy, and immunohistochemistry.

Mucosa-associated Lymphoid Tissue Lymphoma of the Trachea

Journal of Bronchology & Interventional Pulmonology, 2012
Primary malignant lymphoma of the trachea is rare. We report a case of a 60-year-old woman with a mucosa-associated lymphoid tissue lymphoma of the trachea and review the existing literature. This case highlights the importance of including intraluminal lesions in the differential diagnosis when a variable degree of obstruction is seen on pulmonary ...

Clinical course of duodenal mucosa‐associated lymphoid tissue lymphoma: Comparison with gastric mucosa‐associated lymphoid tissue lymphoma

Journal of Gastroenterology and Hepatology, 2020
AbstractBackground and AimThere are few cases of duodenal mucosa‐associated lymphoid tissue (MALT) lymphoma reported in the literature, and little is known about the clinical course of this disease. Here, we aimed to characterize the clinical features of duodenal MALT lymphoma by comparison with gastric MALT lymphoma.MethodsThirteen patients diagnosed ...

Mucosa-Associated Lymphoid Tissue Lymphomas

2003
Abstract Non-Hodgkin’s lymphoma (NHL) of the gastrointestinal (GI) tract accounts for 4% to 20% of all NHL, making the GI tract the most common extranodal site of NHL presentation. Most of these lymphomas arise from mucosa-associated lymphoid tissue (MALT).

MALT (»mucosa-associated lymphoid tissue«)

2016
Das mukosaassoziierte lymphatische Gewebe (MALT) in der Darmschleimhaut ist fur die Infektionsabwehr und die Ausbildung von Immunfunktionen des gesamten Organismus bedeutend. Das MALT besteht aus induktiven Regionen (Peyer’s Patches, isolierte Lymphfollikel, Appendix), der IgA-Immunantwort und Effektorstrukturen (Lamina propria, exokrine Drusen ...
