Port Wine Stains

The goal of this clinical trial is to learn if the use of rapamycin cream can be used as a treatment together with pulsed dyed laser in treating port wine stain birthmarks. The main question it aims to answer is: Will rapamycin cream and laser treatment show a greater improvement in appearance of port wine birthmarks, compared to treatment with placebo cream and laser? Researchers will compare two concentrations of rapamycin cream (0.6% or 1.0%) with placebo treatment to see if appearance is improved following 12 weeks of treatment. Participants will receive laser treatment of their port wine birthmark and then apply the rapamycin or placebo cream daily for 12 weeks. Patients will visit the clinic every 4 weeks for checkups and tests.

In this study the investigators aim to optimize Port-Wine-Birthmark (PBW) laser therapy in children in order to reduce the number of laser treatments required for clearance and improve outcomes for refractory cases. This approach also seeks to reduce the frequency with which children require general anesthesia for treatment.
