Foreign bodies in the esophagus are common in the field of otolaryngology. They are usually due to ingestion of coin, especially in the cases of children. Almost always, coin in the esophagus can be easily removed under esophagoscope. However, untoward complications have not infrequently ensued. The authors have recently experienced an interesting case of foreign body in the mediastinum. It was found to be a 50-won coin that had remained between the tracheal bifurcation and the esophagus for 13 years without causing any serious complication. At age of 16 years, he visited E.N.T. department of our hospital, where the coin was safely removed by trans-thoracic approach under general anesthesia. So we report this case along with literature review.
