Introduction
|
A port-wine stain is a vascular malformation of developmental origin with ectasia of superficial dermal capillaries. It is occasionally associated with congenital glaucoma, the Sturge-Weber syndrome (intracranial angiomas) and the Klippel-Trenaunay-Weber syndrome (limb hypertrophy). |

History
-
A port-wine stain is almost always present at birth
-
The Sturge-Weber syndrome
- The usual cutaneous finding is a unilateral port-wine stain, involving roughly the areas served by the ophthalmic and maxillary divisions of the trigeminal nerve
- Epilepsy occurs in up to 90% of cases - once seizures start neurological deterioration with mental retardation can be rapid
- Patients without seizures fare much better
- Glaucoma and other eye complications arise in 50-60% of all cases
-
Early referral is indicated
-
The Klippel-Trenaunay syndrome
- A rare disorder with a port-wine stain extending down the limb, increased limb size, varicose veins and other soft tissue swellings
- The condition is associated with many other developmental defects and high rates of deep vein thromboses and pulmonary emboli
Clinical findings
-
Distribution
- The face is the most commonly affected site
-
The nape of the neck and upper trunk are other common sites, although any part of the body can be affected
-
Morphology
- Pink to deep red / purple patches
- Often unilateral with a distinct cut off
- Lesions tend to persist, darken and thicken with age

Management
-
Facial lesions need early referral for the following reasons:
- To consider the possibility of the Sturge-Weber syndrome
- The cosmetic impact of such lesions can be substantial - referral to a dermatology department with laser facilities is appropriate
-
Lesions on or near the eyelid can be associated with glaucoma - where the face is affected both above and below the eye the risk of glaucoma is particularly high. 40% of the cases of glaucoma arise in infancy, but glaucoma can also arise in adults and those at risk need early assessment and long-term follow up with an ophthalmologist
