Abstract
Caustic ingestions are a common cause of injuries to the upper gastrointestinal (GI) tract, most notably the esophagus and stomach. Severity of injury is affected by the nature of the substance, the amount or concentration of the substance, and the duration of direct contact with the mucosa. Typically, cases of caustic ingestion occur more frequently in pediatric patients and in those with psychiatric comorbidities and/or those attempting suicide. Currently, there are no cases in which potassium thiocyanate ingestion resulting in GI sequelae has been reported. We present the first case of caustic mucosal injury to the upper GI tract after potassium thiocyanate ingestion.
