MALT lymphoma (MALToma) is a form of lymphoma involving the mucosa-associated lymphoid tissue (MALT), frequently of the stomach, but virtually any mucosal site can be afflicted.
What is MALT lymphoma?
Lymphoma is divided into 2 broad groups: Hodgkin's lymphoma and non-Hodgkin's lymphoma. MALT lymphoma is a relatively uncommon type of non-Hodgkin's lymphoma. It primarily affects the B lymphocytes.
Gastric MALT lymphoma: A low-grade malignant lymphoma of the stomach associated with chronic infection by the bacterium H. pylori. Three-quarters of gastric MALT lymphomas regress after the eradication of H. pylori with antibiotics.
MALT lymphoma Mucosa-associated lymphoid tissue lymphoma. A type of cancer that arises in cells in mucosal tissue that are involved in antibody production. Also called mucosa-associated lymphoid tissue lymphoma.
MALT Lymphoma (a specific low-grade type) associated with Helicobacter pylori infection and treatment, often involves only treating the Helicobacter pylori with antibiotics, which causes the tumor to regress.
Gastric MALT lymphoma most often develops from chronic Helicobacter pylori infection and the associated inflammation. Other bacterial infections are thought to be involved in the development of MALT lymphoma in other tissues.
Definition MALT lymphomas are solid tumors that originate from cancerous growth of immune cells that are recruited to secretory tissue such as the gastrointestinal tract, salivary glands, lungs, and the thyroid gland.
Primary non-MALT lymphomas of the salivary glands may also occur and appear to have a prognosis similar to those in patients who have histologically identical nodal lymphomas.
This bacteria is also believed to be associated with stomach cancer and a rare type of lymph gland tumor called gastric MALT lymphoma.

MALT lymphoma is a type of lymphoma that sometimes affects the eyes. It is associated with the bacterium Helicobacter pylori (H. pylori), which also causes stomach ulcers.
For example, MALT lymphoma is thought to be caused by a bacterium known as Helicobacter pylori. If this lymphoma is diagnosed very early, the lymphoma will sometimes go away if the bacterium is eliminated from the stomach with antibiotics.
If you're diagnosed with stomach cancer or gastric MALT lymphoma, your doctor may prescribe a double-antibiotic treatment in addition to the options you may have for treating the cancer, such as surgery, radiation therapy or chemotherapy.

May be diagnosed in the bowel and be called a MALT lymphoma. The area most commonly involved is the stomach. Many of these are low grade tumours with minimal disabling effects and non-disabling treatments.
pylori is responsible for the majority of duodenal and stomach ulcers. There is now strong evidence that H. pylori increases the risk of stomach cancer and MALT lymphoma, a rare form of stomach cancer.
Curing the infection can be expected to cure the gastritis and decrease the risk of other gastrointestinal diseases associated with gastritis, such as peptic ulcer disease, gastric cancer, and MALT lymphoma.
which causes stomach ulcers, is associated with increased risk for mucosa-associated lymphoid tissue lymphomas (MALT). (The use of antibiotics to get rid of the bacteria may cause remission in some patients who have an early stage of MALT lymphoma.) ...
One out of every six patients with H. pylori infection will develop ulcers of the duodenum or stomach. H. pylori also is associated with stomach cancer and a rare type of lymphocytic tumor of the stomach called MALT lymphoma.
