Gastric pseudopolyposis: a new clinical manifestation of XXXX .

@entity4726 @entity845 @entity75 @entity194 @entity3621
Three cases of @entity3621 associated with @entity75 of the body of the stomach are presented. The endoscopic congo-red test showed the red to black color changes of the sprayed congo-red only on the top of the polypoid lesions. The endoscopic @entity845 -blue test revealed no dye absorption on the antral mucosa or on the top of the polypoid lesions, while the dye was absorbed on the flat mucosa surrounding the top of the polypoid lesions. Histological examinations revealed well-preserved oxyntic glands on the top of the polypoid lesions. The flat mucosa showed marked @entity194 . There have been several reports of experimental models of @entity3621 , where chief and parietal cells decreased in considerable number. These findings and the experimental models suggest that the polypoid lesions resulted from @entity4726 . The top of the polypoid lesions is the residual oxyntic glands. The lesions, therefore, should be called "gastric pseudopolyposis." The spontaneous disappearance of the polypoid lesions seen in one case is thought to be a result of a further progression of the @entity4726 . A pronounced G-cell increase was noted in the antrum and lower body of the stomach. This is considered a secondary phenomenon following the marked reduction of acid secretion.
