[Stomach MALT-lymphoma with marked plasmocytic differentiation: a variant of Mott's cell tumor].
Stomach MALT-lymphomas have a specific feature of clinical behaviour and prognosis, this being reason to differentiate it from others gastric lymphoma's variants. 75 cases of gastric MALT-lymphomas having "classical" morphological features with polymorphic tumour infiltration. We described the only case of MALToma in our series characterised by a strong marker tendency of monoclonal plasmocytic differentiation (including plasmoblasts) with 'signet-ring' cells, Dutcher and Russel bodies using morphological, histochemical and immunohistochemical methods. We suppose this case to be MALT lymphoma with Mot's cell differentiation.
