Associations
Gastric MALT lymphoma is frequently associated (72–98%) with chronic inflammation as a result of the presence of Helicobacter pylori, potentially involving chronic inflammation, or the action of H. pylori virulence factors such as CagA.
The initial diagnosis is made by biopsy of suspicious lesions on esophagogastroduodenoscopy (EGD, upper endoscopy). Simultaneous tests for H. pylori are also done to detect the presence of this microbe.
In other sites, chronic immune stimulation is also suspected in the pathogenesis (e.g. association between chronic autoimmune diseases such as Sjögren's syndrome and Hashimoto's thyroiditis, and MALT lymphoma of the salivary gland and the thyroid).

Famous quotes containing the word associations:
“Writing prejudicial, off-putting reviews is a precise exercise in applied black magic. The reviewer can draw free- floating disagreeable associations to a book by implying that the book is completely unimportant without saying exactly why, and carefully avoiding any clear images that could capture the reader’s full attention.”
—William Burroughs (b. 1914)
“Hardly a man in the world has an opinion upon morals, politics or religion which he got otherwise than through his associations and sympathies. Broadly speaking, there are none but corn-pone opinions. And broadly speaking, Corn-Pone stands for Self- Approval. Self-approval is acquired mainly from the approval of other people. The result is Conformity.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“Wild as it was, it was hard for me to get rid of the associations of the settlements. Any steady and monotonous sound, to which I did not distinctly attend, passed for a sound of human industry.... Our minds anywhere, when left to themselves, are always thus busily drawing conclusions from false premises.”
—Henry David Thoreau (1817–1862)
