A 77 yr old male was referred for dyspnoea and recurrent infections of the lower airways for the previous five months. On the lateral chest roentgenogram a process in the tracheal area was found, and during bronchoscopy a polypoid tumour was seen about four centimetres above the main carina. It appeared to be a benign endotracheal tumour which was removed after coagulation by a Neodymium yttrium aluminium garnet (YAG) laser.
