Explain of Gastrointestinal Pathology

24.Acute gastritis, gross

Here are some larger areas of gastric hemorrhage that could best be termed "erosions" because the superficial mucosa is eroded away. Note the rounded outlines of these erosions--perhaps very similar to the end of a nasogastric tube. Hmmm, perhaps it is best not to apply too much suction to the NG tube.
Ingestion of acids and alkalies produces severe mucosal damage.
Alkalies (lye) are worse and usually produce ulceration that extends into and through the muscular wall of esophagus and/or stomach.Here, a patient swallowed sulfuric acid. The acid charred the gastric mucosa.
