The terms low-grade MALToma
and high-grade MALToma
formerly were used to describe such lesions, but, as discussed above, the diagnosis of MALT lymphoma currently is restricted to a lymphoma composed principally of small lymphocytes and should not be used to classify large B-cell lymphomas, including those associated with a MALT component or arising in a MALT site.
Ayni hastada lenfoma, MALToma ve karsinoma birlikteliginin nadir gorulmesi nedeniyle, literatur bilgileri esliginde sunmayi uygun bulduk.

We want to present this case with literature reviews, as lymphoma, MALToma and carcinoma in the same patient is extremely rare.
Retired TV camera supervisor Chas was diagnosed eight years ago with maltoma, a rare form of non-Hodgkin's lymphoma that attacked his lungs.
Research has shown that maltoma responds well to surgery so, as part of my treatment, doctors removed two thirds of my right lung with the tumour.
Primary lymphoma of the salivary glands is rare and is classified as MALT (mucosa-associated lymphoid tissue) lymphoma, or MALToma
Diffuse large B-cell lymphoma is the most common subtype of non-Hodgkin lymphoma in this site, in contrast to ocular adnexal lymphoma in which MALToma (MALT lymphoma) is the most common subtype.

6-8] Gloeckner et al recently described a large cell lymphoma with a marginal zone growth pattern presenting as multiple colonic polyps, and Schmid et al described 3 cases of colorectal MALTomas
(2 low grade and 1 mixed low and high grade) presenting as solitary polyps.
