Lint: malt-lymphoma

"Mucosa-associated lymphoid tissue (MALT) lymphoma (MALToma), formally termed extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (ENMZL), is a type of low-grade extranodal non-Hodgkin lymphoma."

"In the 5^th edition of the WHO classification of haematolymphoid tumours, it is a mature B-cell neoplasm termed extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (EMZL). EMZL, or MALT lymphoma, is a distinct entity from nodal marginal zone lymphoma, splenic marginal zone lymphoma (SMZL), and primary cutaneous marginal zone lymphoma (PCMZL). These entities share similar histopathological features, but differ significantly in their aetiologies."

"lung and upper airways (see: BALT lymphoma)"

"MALT lymphomas arise in epithelial tissues where lymphoid cells are not usually found. Chronic infection/inflammation has been implicated in the pathogenesis, for example, Helicobacter pylori infection with gastric MALT lymphoma, and Sjögren disease with salivary gland MALT lymphoma ^1,3. Less than 10% transform from low-grade to high-grade disease ⁴."

"associated with H. pylori infection in 90% of cases ⁷"

"associated with Chlamydia psittaci ⁸"

"MALT lymphoma is considered an indolent disease with a good prognosis. Treatment should be tailored to the affected organ and may consist of surgery, chemotherapy, and/or radiation therapy ². Antibiotics can be used to treat gastric MALT lymphoma if H. pylori positive; there is a lack of evidence for their use in treating non-gastric MALT lymphoma ⁷."
