Ingestion of household bleach is usually benign, as it is a mild esophageal irritant that rarely produces any significant mucosal injury or necrosis. Therefore most poison centers advocate a conservative home management treatment. In this report, we present a case of esophageal rupture due to ingestion of household bleach. A 90-year-old woman visited our emergency department complaining of unexplained mild dyspnea and sudden puffiness of the face. After a thorough investigation, she was found to have an esophageal rupture with subcutaneous emphysema, which was the result of a suicide attempt by ingesting household bleach at around 06:00am that morning. Emergency surgery was performed to repair the esophageal rupture. We have reviewed the literature and discuss the possible mechanisms relating to esophageal rupture.
