Tadi, Klippel Trenaunay Weber Syndrome, in StatPearls. Piram, M., et al., Sturge-Weber Syndrome in Patients with Facial Port-Wine Stain.Pediatric Dermatology, 2012.Pulsed-dye laser (PDL) is the most effective laser therapy. Laser therapy may be more effective during the neonatal period, so early referral is recommended. Laser therapy can be considered for treatment of port-wine stains. Children with PWSs involving their eyelids or forehead should undergo a thorough ophthalmic examination to evaluate for glaucoma. For PWSs involving the lumbar region, MRI or ultrasound should also be considered to evaluate for associated spinal dysraphism. In a child where SWS is suspected based on distribution of the PWS or presence of neurologic symptoms, an MRI is indicated to evaluate for leptomeningeal or brain abnormalities. Imaging is only indicated when evaluating for associated syndromes or abnormalities. Classic PWSs do not necessitate further work-up. The diagnosis of PWSs is generally clinical and based on classic features, timing of onset, and evolution.

Nevus simplex are generally less demarcated, pale pink to rose colored, and are more centrally located. Nevus simplex (“salmon patch”) Port-wine stains typically have a more lateralized location, are more intense in color, and have sharply demarcated borders.Features of Klippel-Trenaunay Syndrome include capillary malformation, limb hypertrophy, and venous abnormalities.Features of SWS include PWSs involving the trigeminal nerve distribution, neurologic abnormalities, eye abnormalities.Over time, lesions may darken or thicken, and can develop vascular papules and nodules.Most commonly presents as unilateral lesions on the head and neck, but can occur on any part of the body.PWSs present at birth as bright or deep red, blanchable macules or patches.While the vast majority of port-wine stains are congenital, there have been rare reports of acquired port-wine stains following trauma. Males and females are equally affected and there is equal prevalence between premature and full-term infants. The incidence of PWSs is approximately 3 of every 1000newborns. Some of these patients have PIK3CA mutations and should be monitored for rarely associated Wilms tumor with q3month abdominal ultrasounds until age 8. We now refer to such patients as capillary malformation with somatic overgrowth.

The term Kippel-Trenaunay Syndrome has gone out of favor.Pulsed-dye laser(PDL)is the most effective laser therapy for PWSs.PWSs can be associated with syndromes, such as SWS and Klippel-Trenaunay Syndrome, or other complications including glaucoma and/or spinal dysraphism.Over time, PWSs can darken in color, thicken, and develop nodularity.A mutation in GNAQ has been implicated as a cause of PWSs.

PWSs are congenital, capillary malformations that present as red macules or patches.

Both PWSs and SWS are caused by a somatic mosaic activating mutation in GNAQ, resulting in mitogen-activated protein kinase signaling causing increased cell proliferation and decreased apoptosis. PWSs involving the lower back or periocular area can also be associated with abnormalities such as spinal dysraphism or glaucoma, respectively. While PWSs are most commonly an isolated finding, they can also be associated with syndromes such as Sturge-Weber Syndrome (SWS) and Klippel-Trenaunay Syndrome. A port-wine stain(PWS), also known as nevus flammeus, is a cutaneous capillary malformation most commonly involving the head and neck.
