Kambiz Eftekhari Department of Pediatrics, Pediatric Gastroenterology and Hepatology Research Center, Bahrami Children’s Hospital, Tehran University of Medical Sciences, Tehran, Iran. 2019 12 03 2020 02 20 Ingested Foreign Bodies (FB) frequently occur in pediatric patients. The most commonly ingested foreign bodies are coins, magnets, batteries, small toys, jewelry, buttons, and bones in decreasing order of frequency. A three-year-old boy referred to the emergency room with incidental ingestion of an ampoule of epinephrine. The radiography data demonstrated the location of the ingested ampoule in the stomach. The upper endoscopy was performed; however, the object had already passed through the pylorus. The following day, he passed the ampoule without complications. Our case was pretty unique because the most commonly ingested FBs in the pediatric population include coins followed by magnets, batteries, and so on. Asymptomatic patients having no dangerous FB could be observed until either presenting something abnormal or uneventfully passing the FB. https://crcp.tums.ac.ir/index.php/crcp/article/view/318 https://crcp.tums.ac.ir/index.php/crcp/article/download/318/351
