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.

Morphology of mucosa-associated lymphoid tissue in odontocetes

Microscopy Research and Technique, 2016
This 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.

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 ...

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.

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 ...

在呼吸道、消化道、泌尿生殖道黏膜及黏膜下存在无结构、散在的淋巴细胞.有结构的黏膜相关淋巴组织主要存在于回肠末端及支气管黏膜下[1].其最具特征的结构为Peyer斑(Peyer′s patches,1667年首先由Peyer描述而得名).有结构的黏膜相关淋巴组织与淋巴结的淋巴组织结构相似,但无包膜.单个Peyer斑呈卵圆形,由生发中心、帽区及宽阔的边缘带B细胞构成.其外围为相邻的副皮质区样的T细胞区.边缘区的B细胞可进入覆盖Peyer斑的圆顶区上皮内(这些上皮内的B细胞与小肠其他部位上皮内的T细胞有别).此外,固有膜内的浆细胞也是黏膜相关淋巴组织的一个组成成分。

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.
