Gastric Mucosa-Associated Lymphoid Tissue Lymphoma
American Journal of Gastroenterology, 2003The 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 tissue lymphomas
Current Opinion in Oncology, 1995Mucosa-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.

[Mucosa-associated lymphoid tissue lymphoma].
Zhonghua bing li xue za zhi = Chinese journal of pathology, 2006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。

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 ...

Malignant lymphoma of mucosa‐associated lymphoid tissue
Histopathology, 1987Lymphomas 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.

Sinonasal Mucosa–Associated Lymphoid Tissue Lymphoma
Archives of Otolaryngology–Head & Neck Surgery, 1999Mucosa-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.

Nongastric Mucosa-Associated Lymphoid Tissue Lymphomas
Clinical Lymphoma, 2003Nongastric 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, 2012Primary 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 ...

Primary renal lymphoma of mucosa-associated lymphoid tissue
Urology, 2003Mucosa-associated lymphoid tissue-type lymphomas have recently been recognized as a distinctive form of B-cell malignant lymphoma. In contrast to other types of low-grade lymphomas, these tumors have a tendency to be localized at diagnosis and to be curable with local therapy.

Colonic mucosa-associated lymphoid tissue lymphoma: a case series
Leukemia and Lymphoma, 2019Primary colonic mucosa-associated lymphoid tissue (MALT) lymphoma accounts for less than 0.5% of all colon cancers. We report 9 cases of colonic MALT lymphomas (median follow up: 9 [IQR 1–26] years).
