Hemorrhage due to retrograde prolapse of stomach. An endoscopic diagnosis

A case of recurrent hemorrhage due to localized gastric mucosal congestion from retrograde prolapse during severe retching is described. Historically, this condition may mimic the "Mallory-Weiss syndrome" and endoscopically, this lesion may be mistaken for "gastritis". This rarely recognized condition may be an explanation for some cases of cryptic hematemesis.
