K. Gao, Z. Huang, K.-H. Yuan, B. Zhang and Z.-Q. Hu Side-by-side comparison of photodynamic therapy and pulsed-dye laser treatment of port-wine stain birthmarks British Journal of Dermatology 168
What’s already known about this topic?
To date, several Chinese studies of photodynamic therapy (PDT) for port-wine stains (PWS) indicate that this therapeutic modality is effective and safe for the treatment of PWS of all colour and in all ages.
Our retrospective study suggested that PDT is as effective as pulsed-dye laser (PDL) treatment for pink PWS and more effective than PDL for purple PWS.
What does this study add?
This is the first side-by-side and quantitative comparison of PDL and PDT.
The findings reported here confirm that PDT is at least as effective and safe as PDL, if not superior to, for the treatment of red and purple flat PWS.
