OBJECTIVE: For low-grade intraepithelial neoplasia cases, pharyngolaryngeal lesions equal to or less than 5 mm in size do not generally progress to invasive carcinoma. However, micro-superficial lesions equal to or less than 5 mm that showed rapid growth have been recently encountered. This study aimed to identify the characteristics of preferential progression of lesions equal to or less than 5 mm in size.
METHOD: Gross findings, endoscopic findings and pathological results of 55 lesions measuring equal to or less than 5 mm in diameter were retrospectively reviewed to identify factors that distinguish squamous cell carcinoma or high-grade intraepithelial neoplasia from low-grade intraepithelial neoplasia or non-atypia lesions.
RESULTS: The overall sensitivity, specificity, accuracy, and positive and negative predictive value of background colouration and intrapapillary capillary loop pattern in differentiation of squamous cell carcinoma or high-grade intraepithelial neoplasia from low-grade intraepithelial neoplasia or non-atypia lesions were all 100 per cent.
CONCLUSION: Diagnosis based on background colouration and the intrapapillary capillary loop pattern on narrow-band imaging facilitates the pathological examination of lesions measuring equal to or less than 5 mm.
