Abstract
- Copper sulfate ingestion is a rare cause of corrosive gastrointestinal injury in the Republic of Korea. In developing countries, copper sulfate is chiefly used for agricultural purposes as a pesticide and in the leather industry. It is also used in school science classes in the form of bright blue crystals. Copper sulfate is a powerful oxidizing agent that is corrosive to mucous membranes. Concentrated solutions are acidic, with a pH of 4. We report a case of corrosive gastritis and esophagitis due to accidental copper sulfate ingestion in a 12-year-old boy.
