title: [Erosive petechial gastritis].
abstract: We studied 20 patients in which a variety of erosive gastritis is described. We named it petechial erosive gastritis. We have to bring up that its sequence is due to the presence of the petechiae in the center of the mucosal area. Then in degrees of higher intensity erosions occur also at the center of the area mucosa. Occasionally the erosions meet, become larger and may bleed. An endoscopic classification of petechial erosive gastritis is established it rates mild, moderate, severe and hemorrhagic degrees. Even if the histopathologic study does not keep a strict correspondence with the severity of endoscopic observation of the lesions, it is possible to separate easily a petechial stage from an erosive stage. Demonstration of these lesions at their sequence from petechial to bleeding erosion constitutes an important contribution to the study of acute gastric lesions and it might open a way to a better study of the alterations of the irrigation of the gastric mucosa and the etiology of erosive lesions and acute ulcer.
