A 44-year-old woman with a 12-year history of Sjögren’s syndrome (SS) developed a low-grade mucosa-associated lymphoid tissue (MALT) lymphoma in the parotid gland. Two years later, she presented with generalized lymphadenopathy and hepatosplenomegaly and a follicular lymphoma was diagnosed. To investigate the relationship of the two histologically distinct lymphomas, we re-examined their histol...

Low grade B cell mucosa associated lymphoid tissue (MALT) lymphoma of the stomach is usually an indolent tumour that remains localised for a long time before dissemination occurs. MALT appears in the stomach in response to infection by Helicobacter pylori, which is present in 80-90% of cases. The pathogenesis of the evolution from chronic gastritis to malignant lymphoma has not yet been fully e...

Primary hepatic extranodal mucosa-associated lymphoid tissue (MALT) lymphoma is seen extremely rare compromising 0,016% among non-Hodgkin lymphomas. Association of chronic inflammatory conditions or infectious processes mostly hepatitis B virus (HBV) infection has been reported by scarce number case presentations. Whereas MALT accompanied echinococcus granulosus was described only in one primar...

A 39-year-old previously healthy woman presented with intractable progressive headache and blurred vision over 1 month. Neurologic examination had normal results. Brain neuroimaging showed multiple extra-axial masses and diffuse smooth and nodular thickening and enhancement of the dura of the posterior fossa (figure 1). Pathologic findings of the dura were diagnostic of mucosa-associated lympho...

BACKGROUND AND OBJECTIVES Small B-cell indolent lymphomas postulated to be of a post-germinal center origin include marginal zone lymphomas of the spleen (S-MZL) or lymph nodes (N-MZL) and mucosa-associated lymphoid tissue (MALT) lymphomas and lymphoplasmacytic lymphomas (LPL). The existence of rather aggressive cases stresses the need for new biological prognostic markers. DESIGN AND METHODS...

Gastric lymphomas are rare tumorsand accounts for only 3%. There two groups of lymphomas: mucosa-associated lymphoid tissue (MALT) gastric lymphoma or diffuse large B-cell lymphoma. The management this tumordepends on the histological grade and extension workup. It includes a clinical examination, radiological endoscopic work-up including total ileo-coloscopy in order to look synchronous intest...

Colonic mucosa-associated lymphoid tissue (MALT) lymphomas are rare and a definitive treatment has not been established. Solitary or multiple, elevated or polypoid lesions are the usual appearances of MALT lymphoma in the colon and sometimes the surface may reveal abnormal vascularity. In this paper we report our experience with four cases of colonic MALT lymphoma and review the relevant litera...

BACKGROUND The treatment policy and disease process of mucosa-associated lymphoid tissue (MALT) lymphomas are different from those of other gastrointestinal lymphomas. Chemotherapy has replaced curative surgery as the treatment of choice in gastric lymphomas but the optimal frontline treatment of intestinal lymphomas has yet to be defined. Hence, we attempted to identify the difference in featu...

BACKGROUND Gastric non-Hodgkin lymphoma is a rare tumour that represents approximately 7% of all stomach cancers and 2% of all lymphomas. The most frequent location of gastric MALT (mucosa associated lymphoid tissue) lymphomas is in the antrum in 41% of the cases, and 33% can be multifocal. The risk of spontaneous perforation of a gastric MALT lymphoma is 4-10%. CLINICAL CASE 24 year old male...

BACKGROUND Gastric mucosa associated lymphoid tissue (MALT) lymphoma is a low grade B cell lymphoma histologically characterised by neoplastic B cells surrounding follicles in a marginal zone pattern and selectively infiltrating epithelium to form characteristic lymphoepithelial lesions. AIMS To identify solitary epithelial cells in gastric MALT lymphoma and investigate their nature. METHOD...
