Use of Interventional Bronchoscopy to Manage Solitary Bronchial Squamous Papilloma with Malignant Change-A Case Report

We reported a 74-year-old male patient with multiple comorbidities (diabetes mellitus, hypertension and stroke) who underwent endovascular aortic replacement due to abdominal aortic aneurism. In the postoperative follow-up, a nodule in the left main bronchus was found. Bronchoscopy confirmed a polyp-like lesion in the orifice of the left upper lobe. The biopsy report revealed a squamous cell papilloma with moderate dysplasia. Following that, electrocautery was performed monthly. The 3rd biopsy report revealed papillary squamous cell carcinoma. The patient then underwent positron emission tomography-computed tomography, which showed fluorodeoxyglucose-avid lesions in the left upper lobe and pretracheal lymph node. The patient refused operation and continued to undergo electrocautery. The biopsy report before the 5th electrocautery procedure began found no malignancy. Since then, he has been followed up regularly in our clinic with autofluorescence endoscopy. (Thorac Med 2012; 27: 167-172)
