Extraluminal esophageal coin erosion in children. Case report and review.

Coins are often reported as the most commonly ingested foreign body (FB) in children. They are felt to be benign FBs since they usually pass through the gastrointestinal tract without incident. However, when these objects become impacted within the esophageal lumen, they can perforate the esophagus and migrate extraluminally. Symptoms of the perforation itself are frequently absent, but the potential vascular and suppurative complications may be devastating. We present the 10th reported case of complete extraluminal migration of an esophageal coin, and the only case which was treated without an open surgical procedure. Because of the potential complications, we recommend aggressive surgical intervention as soon as the diagnosis is made.
