摘      要：Russell body gastritis(RBG) is an unusual type of chronic gastritis characterized by marked infiltration of Mott cells,which are plasma cells filled with spherical eosinophilic bodies referred to as Russell *** was initially thought that Helicobacter pylori(***) infection was a major cause of RBG and that the infiltrating Mott cells were polyphenotypic;however,a number of cases of RBG without *** infection or with monoclonal Mott cells have been ***,diagnostic difficulty exists in distinguishing RBG with monoclonal Mott cells from malignant ***,we report an unusual case of an 86-year-old-Japanese man with ***-positive *** the examination of melena,endoscopic evaluation confirmed a 13-mm whitish,flat lesion in the gastric *** endoscopy with narrowband imaging suggested that the lesion was most likely a poorly differentiated *** findings were consistent with chronic gastritis with many Mott cells with intranuclear inclusions referred to as Dutcher *** submucosal dissection confirmed the diagnosis of RBG with kappa-restricted monoclonal Mott *** lymphoma was unlikely given the paucity of cytological atypia and Ki-67 immunoreactivity of monoclonal Mott *** is the first reported case of RBG with endoscopic diagnosis of malignant tumor and the presence of Dutcher bodies.
