[Electron microscope study of localized gastric amyloidosis].
Results of the electron microscopic examination of the local amyloidosis of the stomach are reported. In mucin producing cells of the gastric mucosa a large number of microfilaments indicating the presence of pathologic mucin secretion was revealed. Epithelial cells also exhibited signs of disturbed protein secretion. Electron microscopic features of cells occurring in amyloid deposits described in detail. It is concluded that in the development of local amyloid deposits actively secreting myofibroblasts play an important part.
