Unusual Foreign Bodies in the Respiratory Tract of Children.

BACKGROUND: Diagnosis of a foreign body without history of aspiration has always been a challenge to pediatricians. CASE CHARACTERISTICS: Four cases presented with non-relieving acute or chronic history of respiratory symptoms. OBSERVATIONS: All of them had unusual types of foreign bodies-plastic flower toy, button, sticker or stone in their respiratory tract. OUTCOME: All four patients improved after removal of the foreign body. MESSAGE: A differential diagnosis of foreign body should always be made in an acute or chronic presentation of respiratory cases.
