Gastric lymphoma of the MALT with breast relapse.

The usual features of non-Hodgkin lymphomas (NHL) of the mucosa-associated lymphoid tissue (MALT) include monocytoid B-cell proliferation, and chronic inflammatory precursor lesions. Despite a reputation of being indolent, NHL of the MALT may disseminate to other MALT areas, and raise difficult therapeutic questions. We report a case of gastric NHL of the MALT whose evolution, despite an initial surgical treatment considered radical, was noticeable for a well documented breast relapse.
