[A bronchial polyp and foreign body in an adolescent]

A fifteen-year-old adolescent with recurrent pneumonia in the last two years is presented. The polyp in the lobar bronchus for the right inferior lobe and a foreign body in posterobasal segmental bronchus were found on bronchoscopy. The polyp (patHohistologically confirmed granulomatous tissue) and foreign body (thorny fruit of small caltrops, Tribulus terrestris) were extracted through a rigid ventilatory bronchoscope. The polyp presumably developed from the thorn of the fruit stuck in bronchial mucosa.
