Extranodal marginal zone B-cell lymphoma is a discrete clinicopathologic entity arising in mucosaassociated lymphoid tissue (MALT), characterised by unique pathogenic, histologic and clinical features. MALT B-cell lymphoma occurs more frequently in organs, such as stomach, salivary glands, or thyroid, which acquire lymphoid tissue only after chronic phlogistic events. This occurs in response to...

Primary mucosa-associated lymphoid tissue (MALT) lymphoma arising in the common bile duct (CBD) is extremely rare. In our case of MALT lymphoma, CT and MRI showed long, segmental, irregular wall thickening of the CBD and minimal dilatation of the upstream bile duct. A preoperative diagnosis of cholangiocarcinoma was made, but histologic evaluation confirmed MALT lymphoma of the CBD. We herein p...

Study Design Case report. Objective Most spinal lymphomas occur in the context of systematic lymphomas. Marginal zone lymphoma (MZL) is a type of B-cell lymphoma originating from the marginal zone of B-cell follicles. Mucosa-associated lymphoid tissue (MALT) lymphoma is a type of extranodal MZL and rarely occurs in the central nervous system. To date, there has been only one case report of prim...

the gastrointestinal tract is the most frequently involved extranodal location for malt* lymphomas, but malt lymphomas of the large intestine are rarely observed. a treatment for colorectal malt lymphoma has not yet been established. in colonic malt lymphomas, the literature suggests that surgical resection of localized lesion may be the best choice. in the present case, combination of multi-ag...

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...

Extranodal marginal zone B-cell lymphoma of the mucosa associated lymphoid tissue (MALT-lymphoma) is mot commonly diagnosed in stomach (30%–35%), but exceedingly rare intestinal tract (2%). Consequently, data on this special subgroup are scarce. Out 484 patients with MALt-lymphoma and treated at our institution from 1999 to 2020, 42 (11%) had involvement (24 primary 18 secondary) were restrospe...

Mucosa associated lymphoid tissue (MALT) lymphoma is a lymphoid neoplasm arising in extranodal sites with histologic features similar to those of nodal marginal zone lymphoma. Among the sites where a primary MALT lymphoma arises, the GI tract is the most common whereas the breast represents only 4%. Bilateral involvement of the breasts by a primary MALT lymphoma is exceptional with only 10 case...

Mucosa associated lymphoid tissue MALT lymphoma is a low grade malignancy that arises most commonly from the gastric mucosa. Small intestinal involvement is very rare. The causative relationship between Helicobacter pylori and the gastric MALT lymphoma is a well known issue, but recently there are several data suggesting the role of hepatitis C virus (HCV) infection in the pathogenesis of lymph...

Mucosa-associated lymphoid tissue (MALT) lymphoma of the stomach is the most common extranodal lymphoma of the gastrointestinal tract. It is usually accompanied by Helicobacter pylori infection, and eradication of H. pylori remains the mainstay of treatment for gastric MALT lymphoma. However, there is no consensus on the second-line treatment for patients with gastric MALT lymphoma who do not i...

Lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) was first described by Isaacson et al. in 1983 (Isaacson & Wright, 1984). According to the WHO lymphoma classification, the indolent B cell lymphoma of MALT type is classified as a marginal zone lymphoma, thus called because it originates from the B lymphocytes normally present in a distinct anatomical location (marginal zone) of the...
