[Polypous nonchromaffin paraganglioma of the stomach]

It is reported on the unusual position of a nonchromaffin paraganglioma in the stomach, which in gastroscopy imposed as polyp and was removed. On the basis of the light-microscopic picture, its behaviour during staining and the electronmicroscopic investigations the tumour is classified in the group of the paragangliomata. Since there are no unequivocal histological criteria of malignity, on account of the well-known slow growth of these tumour only the polyp is removed.
