1 Although the pulsed dye laser is often considered of limited value in mature portwine stain, Tan has recently reported excellent results.

2 Conclusion:the confocal microscope is an effective and non-invasive technique to observe the efficacy of photodynamic therapy on port-wine stain.

3 Although there is clinical overlap with DDMS the characteristic port-wine stain is a distinguishing feature.

4 Eventually, most of the lesions couldn't be blanched completely. Therefore, port-wine stain is not cured satisfactorily.

5 On recent years, several techniques have been developed to measure the outcomes of port-wine stain treated with laser.
