Topical photodynamic therapy is the first-line treatment of choice for oral erythroleukoplakia and oral verrucous hyperplasia

摘要

Oral erythroleukoplakia (OEL) and oral verrucous hyperplasia (OVH) are two relatively common oral precancerouslesions. The malignant transformation rate is reported to be18e47% (28% average) for OEL lesions and 3e17% for OVHlesions. The high malignant transformation rates of OEL andOVH lesions highlight the importance of early detection andtreatment of these two types of oral precancerous lesions.
