Early detection and treatment of preneoplastic lesions represents an obvious option to reduce morbidity and mortality from lung malignancies. Until now, radiological detection, sputum cytology, and autofluorescence have shown limited effectiveness as screening methods. Novel technologies such as Narrow Band Imaging (NBI) are showing promising results, but new studies are still needed to evaluate their use as screening methods. Together with early detection, adequate methods of lesion treatment, such as argon plasma coagulation, are needed. This case report concerns a 45-year-old man who was referred for bronchoscopy after his annual checkup. Using NBI technology, a preneoplastic lesion was identified, and treated using argon plasma coagulation. Our experience has shown us that both NBI screening and argon plasma coagulation are very promising, easily implemented, methods.
