Syndrome of iron pill inhalation in four patients with accidental tablet aspiration: Severe airway complications are described.

Iron pill inhalation represents a uncommon cause of syntomatic endobronchial foreign bodies. Unlike foreign body, the direct contact of iron tablet onto the bronchial mucosa results in severe bronchial damage in addition to obstruction and local irritation. Four patients with Iron Pill Inhalation Syndrome are described. All but one patient developed irreversible bronchial stenosis as late post inflammatory complication. Bronchoscopic features and clinical evolution are described in order to reduce the risk of severe side-effects in patients highly suspected for iron pill aspiration.
