Mucosa-associated lymphoid tissue lymphoma

Current Opinion in Hematology, 2002
Since the first description of mucosa-associated lymphoid tissue (MALT) lymphoma in 1983 rapid advances have been made in the understanding of the pathogenesis and underlying molecular events associated with the development of this tumor. Lymphoma arises at extranodal sites in which a pre-existing inflammatory response has provoked the acquisition of ...

Mucosa-associated lymphoid tissue lymphomas

Current Opinion in Oncology, 1995
Mucosa-associated lymphoid tissue (MALT) lymphomas are a distinct subgroup of non-Hodgkin's lymphoma with a particular clinicopathologic behavior. The gastrointestinal tract is involved in two thirds of the cases, but it may be observed in lung, breast, bladder, conjunctiva, kidney, liver, skin, salivary glands, thyroid, and thymus.

Sinonasal Mucosa–Associated Lymphoid Tissue Lymphoma

Archives of Otolaryngology–Head & Neck Surgery, 1999
Mucosa-associated lymphoid tissue (MALT) is a specialized form of lymphoid tissue that may be acquired at sites in response to chronic inflammation. Most low-grade, B-cell, non-Hodgkin lymphomas that occur at extranodal sites derive from acquired MALT.

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.

Gastric Mucosa-Associated Lymphoid Tissue Lymphoma

American Journal of Gastroenterology, 2003
The connection between Helicobacter pylori and gastric mucosa-associated lymphoid tissue (MALT) lymphoma is well established. H. pylori infection causes an immunological response, leading to chronic gastritis with formation of lymphoid follicles within the stomach.

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.

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.

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 ...

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 ...
