[A case of tuberculous bronchial stenosis, diagnosed after 50 years of pulmonary and laryngeal tuberculosis].

A 82-year-old woman was referred to our department for further evaluation of her atelectasis in the left lower lobe of the lung which was found under preoperative examination for a renal pelvic tumor resection. Bronchoscopic examination was performed, and a pin-hole stenosis at the orifice of the left main bronchus was detected. Tuberculous bronchial stenosis was suspected because she had pulmonary and laryngeal tuberculosis 50 years ago. The dilatation of the stenosis was supposed to be necessary in order to prevent a pulmonary complication during the perioperative period. The stenotic area was dilated using argon plasma coagulation. Eight weeks after the procedure, a bronchoscope 6mm in external diameter could pass the dilated area. We reported a rare case with tuberculous bronchial stenosis in which the patient had never experienced a severe complication for 50 years despite the pin-hole stenosis in the left main bronchus.
