In previous papers the technique of endobronchial placer mining for neoplastic cells was discussed.* In order to secure better specimens of bronchial mucus it was suggested that flexible-tip aspirating tubes be used because of the ease and accuracy with which the lumens of smaller bronchi can be explored. Suction apparatus, such as the Clerf and the Carabelli unit, were discussed.
Recently an unusual hazard was encountered during the evaluation of a patient suspected of bronchogenic carcinoma. Although it was a routine examination with no unusual circumstances, the flexible tip of the straight tube of a Carabelli aspirator-irrigator broke off while the unit was in the right lower lobe bronchus. Fortunately, the missing tip was located quite easily within reach in the lumen of the medial basal segment of the right lower lobe and removed with the foreign-body forceps. The cell-collecting unit had been in use for about one year and
