Correlation between the hemoporfin‐mediated photodynamic treatment response and the dermoscopy vascular pattern in patients with a port‐wine stain: a prospective study

There is a clear correlation between the efficacy of PDT and the dermoscopy pattern in patients with PWS. Dermoscopy may therefore provide very useful clinical information prior to treatment in these cases. In addition, the vascular manifestations of PWS determined by dermoscopy help to predict response to PDT and manage patient expectations.
