title: [Ulcerative processes of the stomach].
abstract: Ulceration of the gastric mucosa is a consequence of a pathological process and it can be subdivided into erosions and ulcers according to depth of penetration. In most cases the lesions are of peptic origin; they may however, be caused by disturbed local circulation, disintegrating tumor tissue and specific diseases like sarcoidosis, tuberculosis, Crohn's disease and syphilis. Such lesions may also be caused by acid burn. Since macroscopic findings during endoscopy may be misleading, all gastric ulcers should be investigated by biopsies, with the possible exemption of diffuse acute or chronic erosions.
