A foreign body in the nose rarely causes halitosis in childhood. Some foreign bodies like metals can stay in the nose for years without any symptoms. We report a case of 14 year old male patient followed up because of JRA (Juvenile rheumatoid arthritis) for 2 years and he had a complaint of halitosis for 10 years. A disk battery was removed from the nose in an operation. The patient was investigated because of possible chronic lead poisoning.
