RT Journal Article SR Electronic T1 An airway traffic jam: a plastic traffic cone masquerading as bronchial carcinoma JF BMJ Case Reports FD BMJ Publishing Group Ltd SP bcr-2017-220514 DO 10.1136/bcr-2017-220514 VO 2017 A1 Nicholas Denny A1 Usman Maqsood A1 Stephen Fowler A1 Mohammed Munavvar YR 2017 UL http://casereports.bmj.com/content/2017/bcr-2017-220514.abstract AB Tracheobronchial foreign body (TFB) aspiration is a common occurrence in children compared with adults. Long-standing cases of TFB aspiration during childhood presenting in an adult have rarely been reported. We report the unique case of an endobronchial Playmobil traffic cone that went undetected for 40 years and presented as a suspected bronchogenic carcinoma. This was subsequently removed successfully with flexible bronchoscopy. To our knowledge this is the first case of a TFB that was overlooked this length of time.
