Spontaneous endobronchial erosion and expectoration of a retained intrathoracic bullet: case report.

In all four previously reported cases of endobronchial erosion from retained intrathoracic foreign objects, the object eventually required surgical removal. We report the case of a patient with a bullet in the left hemithorax who developed bronchial erosion and hemoptysis 3 months after the injury, with subsequent expectoration of the bullet. Although most foreign bodies within the thorax pose no special problems, migration of the object or the development of symptoms warrants investigation and possibly subsequent surgical removal of the object.
