OBJECTIVE: Narrow-band imaging is widely used in the diagnostic work-up of oral lesions. Different oral subsites present three epithelial types (1, 2a and 2b), each with a different structure and function. The aim of this study was to analyse and describe the different vascular patterns seen on narrow-band imaging according to oral epithelial type and histology. MATERIALS AND METHODS: The narrow-band imaging photographs of healthy, dysplastic and neoplastic oral mucosa were retrospectively reviewed and divided according to epithelial type and histology. The different narrow-band imaging patterns were analysed, related to the clinical appearance of the specific area, accurately described and drawn by a professional designer. RESULTS: The photographs of 302 patients were considered. Six patterns were identified: Normal mucosa exhibited different appearance in each type of epithelium; dysplastic mucosa presented the same pattern in type 1 and 2a epithelia, which differed from that of type 2b epithelium; in cancer, mucosal appearance was identical irrespective of epithelial type, due to complete vascular destruction. CONCLUSIONS: The proposed classification could serve as a guide for clinicians approaching narrowband imaging, especially at early stages of the learning curve, to differentiate normal mucosa from malignant lesions and possibly reduce the number of unnecessary biopsies.
