I recently posted that my son had a PWS on his right arm and we weren't sure if he also had KT. I was so very happy to hear the doctor(2 opinions) say that he doesn't appear to have Klippel Trenaunay. We will do a follow-up in 6 months. The doctor said it is called a reticulate port wine stain. How does a reticulate port wine stain differ then a PWS? He suggested not to do laser at this point. Is it true that the earlier you do laser the better the results?
