Port wine stain

Introduction to Port Wine Port wine stains, also known as wine-like mites or telangiectasia, occur in birth, occur in the face, neck, mostly unilateral, occasionally bilateral, sometimes involving the mucosa. The damage starts from a small or a few reddish, dark red or purple red patches, which are irregular in shape, with clear boundaries and no higher than the leather surface. The telangiectasia can be seen, and the partial or complete fading of the pressure is smooth. As you age, the color darkens and turns purple. 40% of patients will gradually expand their lesions. They can thicken and develop nodules before the age of 40, and are prone to bleeding after trauma. Mainly surgical resection, on the one hand after the removal of lesions need skin grafting, usually choose full-thickness skin or medium-thickness skin, the effect is better, but pay attention to the authority to select the inner side of the upper arm as the donor site. On the other hand, the lesion is large, and the suture can not be directly sutured after surgical removal of the port wine stain. It is necessary to use the adjacent flap to transfer the repair, or use tissue dilator therapy, that is, implant the tissue expander around the lesion, 2 to 3 months later. Take out, the local skin expansion is ready, and then repaired. basic knowledge The proportion of illness: 0.03%--0.05% Susceptible people: no special people Mode of infection: non-infectious Complications: hemangioma pediatric hemangioma

Causes of port wine stains

Congenital factors (35%):

During the embryonic development process, especially in the early stage of vascular tissue differentiation, due to the small-scale misconfiguration of the control gene segment, the tissue differentiation of its specific part is abnormal, and it develops into port wine stain.

Estrogen levels (29%):

It has been observed that the incidence of girls with port wine stains is higher than that of boys. Estradiol levels are found in hemangiomas. Estradiol is an estrogen in the human body, indicating that it is related to estrogen levels.

Port wine stain prevention

Port wine stain complications Complications hemangioma pediatric hemangioma

1. Growing on the limb: If the limb is hypertrophy, be careful of abnormalities in the skeletal muscles.

2. Long in the upper third of the face: Be careful about whether to merge the eyes and nerve abnormalities.

3. Long in the midline of the back: Be careful to combine the abnormalities of the blood vessels inside the lower ridge.

Symptoms of port wine stains common symptoms erythema nodules vascular malformation bleeding tendency

Port wine stains are generally common:

First, the port wine stains are initially pale red, dark red or purple red spots of different sizes. It can be seen that the capillaries are dilated, the surface is smooth, the compression will fade, the age of the age will increase, and 65% of patients will expand. It can be thickened or nodules before the age, and it is easy to bleed after trauma. Port wine stains are relatively flat patches of numerous expansional capillaries. The area of the lesion increases with the growth of the body and will not last for life.

Second, port wine stains can occur in any part, mostly in the face, it also affects the ocular nerve and maxillary nerve, 15% will cause glaucoma, 1% - 2% of patients with ipsilateral pial vascular malformation, Known as the Sturge-Weber syndrome.

Third, port wine stains is a common skin lesion phenomenon, and now there are more patients, and port wine stains continue to grow with the age of patients.

Fourth, port wine stains, also known as wine-like mites or telangiectasia, often appear shortly after birth or birth, common in the neck, head, head, etc., mostly unilateral, rarely bilateral Sometimes it involves the mucous membranes.

The damage starts from a small or a few reddish, dark red or purple red patches, which are irregular in shape, with clear boundaries and no higher than the leather surface. The telangiectasia can be seen, and the partial or complete fading of the pressure is smooth. As you age, the color darkens and turns purple. In 65% of patients, the lesions will gradually expand. Before the age of 40, they can thicken and appear nodules, and they are prone to bleeding after trauma.

Diagnosis and identification of port wine stain

diagnosis:

Before the age of 40, they can thicken and appear nodules, and they are prone to bleeding after trauma.

Differential diagnosis:

1, strawberry-like port wine stains: KTP532 laser treatment, 32P application are very effective. KTP532 laser should be selected for better economic conditions. Q-switched skin laser (easy bleeding) is not available. If the economy is very difficult, 32P can be applied, but the frequency of application should not be too much, so as to avoid excessive exposure of children, or two A combination of methods. Sponge-colored port wine stains: it is not suitable for laser treatment, and can not be applied with 32P. The most effective method is to inject 32P.

2, erythematous rash: is a very common symptom of skin diseases, many skin diseases have this symptom.

3. Transient lupus erythematosus: The main clinical feature of systemic lupus erythematosus is edematous erythema on both sides of the cheek. The erythema on the bridge of the nose is often connected with the cheek erythema on both sides to form a butterfly-like rash.

4, ankle erythema: lupus nephritis systemic manifestations: intermittent fever; erythema erythema, due to the shape of a butterfly, also known as butterfly erythema; painless oral ulcers; multiple joint swelling and pain; epilepsy or mental disorders; cold hands and feet It becomes pale, turns to purple after warmth, and then returns to normal color, also known as Raynaud's phenomenon.
