Abstract
The patient was a 37-month-old male. He had vomitted at table with increasing frequency for about two years. He was admitted to a local hospital for treatment of dehydration, and was pointed out esophageal stenosis due to the mediastinal mass. The mass was located in, the mediastinum between left main bronchus and aortic arch, possessed abscess cavity and calcified body arround the esophageal wall. We carried out right 4th intercostal thoracotomy and longitudinal esophagotomy, and removed the foreign body (a plastic sucking disk) buried in granulation tissue. Postoperative course was uneventful. Probably the episode "misintaking the foreign body" occured two years ago. The ingested foreign body developed perforation of the esophageal wall and inflammatory mass was formed in the mediastinal region arround the esophageal wall. The esophageal stenosis was gradually progressed.
