  • Pathophysiology
  1. Persistent fetal vessels
  2. Dilated dermal capillaries (telangiectases)
  • Differential Diagnosis
  1. Port-Wine Stain (Nevus Flammeus)
    1. Contrast with Nevus Simplex which is typically bilateral
  • Signs
  1. Flat, pink (or salmon colored) vascular patch
  2. Blanch on compression
  3. May become more prominent with crying
  4. Distribution and Course: Often symmetric - involving the bilateral face

      1. Resolves spontaneously in 95% of cases
    2. Upper Eyelids
      1. Resolves spontaneously in 100% of cases
    3. Nape of neck ("Stork bite")

      2. Persistant lesions will usually cover with hair
  • Management
  1. No intervention typically needed as these resolve spontaneously in most cases
    1. Most lesions by 18 months (many lesions resolve while still newborns)
  2. Flash-Lamp pumped pulse dye laser (FPDL) in persistent cases
