Recurrent pneumonia caused by a migrated esophageal foreign body.

The accidental ingestion of fish bones is common. However, the complication of migration wherein the fish bone penetrated through the esophagus and into the right upper lobe is extremely rare. In this case, we present a rare case of recurrent pneumonia caused by a migrated esophageal foreign body. The case had been misdiagnosed for 5 years. A right upper lobectomy was performed; a fish bone was found in the lung parenchyma.
