D.Y. Ko, K.H. Kim and K.H. Song A randomized trial comparing methyl aminolaevulinate photodynamic therapy with and without Er:YAG ablative fractional laser treatment in Asian patients with lower extremity Bowen disease: results from a 12-month follow-up British Journal of Dermatology 170
What's already known about this topic?
- Methyl aminolaevulinate (MAL) photodynamic therapy (PDT) is a promising treatment for Bowen disease.
- Use of an Er:YAG ablative fractional laser (AFL) improves the MAL penetration into deeper portions of lesions.
What does this study add?
- We show that compared with conventional MAL-PDT, Er:YAG AFL-assisted MAL-PDT provides better efficacy in treating Bowen disease and with fewer sessions.
