Bright red spot nevus treatment, what is bright red spot nevus

Bright red nevi are more difficult. At present, laser is mainly used, and pulsed dye laser is a gold standard at present, with good effect and high safety. Photodynamic** is to inject a photosensitizer into the blood vessels to irradiate the laser, and the laser interacts with the photosensitizer to have a destructive effect on the blood vessels.

It can effectively clear the lumen of the blood vessels, so that the skin lesions will disappear, and some people can achieve no traces.

The cause of the appearance of bright erythema nevus is due to the lack of nerve innervation of the blood vessels at the lesion site, which causes the capillaries to dilate and congest, which initially appear as red or pink patches, and later deepen with age, becoming bright red and purple, and can be thickened into nodules, irregular shapes, partially or completely faded, and the surface is smooth. The current method is laser removal surgery.

Nowadays, many places have specialized hospitals for hemangioma, and hemangioma should be determined according to factors such as the type of lesion, location and age of the patient. At present, the first method has shell excision, radiation, hormone, low temperature, laser, sclerosing agent injection, etc., generally does not use surgery, surgery is a traditional method, not easy to heal, great harm to the patient, there will be various complications after the operation, so that the patient's body is a great degree of harm, and it is easy to leave scars and**. Because of the difference in blood flow of hemangioma, it is not possible to adopt a single method, and it is recommended to use a variety of minimally invasive combinations to absorb their respective advantages, and the long-term efficacy is better, especially the aesthetics and the development of local tissues in the later stage.

Bright red nevus is a microvenous malformation, generally after birth, and then with age, the lesion from pink-dark red-purple-red, gradually deepening, and the lesion can grow small purple-red nodules, which are enlarged and easy to bleed. (PWS) is a benign, congenital vascular malformation characterized histologically by enlarged and dilated vessels in the superficial dermis. The incidence rate of infants at birth is 0 3 -0 5%, and the blood vessels are mostly superficial, with an average depth of 0 46 mm, and appear as flat, pale pink spots.

It usually occurs at birth or shortly after birth, usually on the face, neck, and scalp, and is mostly unilateral and occasionally bilateral, sometimes involving mucous membranes. The lesion begins as one or more pale red, dark red, or purplish-red patches of different sizes, irregularly shaped, with clear borders, not high above the skin surface, telangiectasia can be seen, partial or complete discoloration of the pressure, smooth surface, occasionally warty or nodular. Occasionally, it resolves spontaneously in the forehead, nasal bridge, or occipital region, and is larger or more extensive, often persisting for life.

Bright red nevi can occur anywhere on the body, but mainly in the trigeminal nerve of the face, the collateral area, and the neck. With age, the blood vessels continue to expand, the bright red nevus gradually deepens in color, dark red or purplish-red, the skin lesions thicken and produce nodules, the average age of 37 years after 2 3 cases of hypertrophy of skin lesions, nodules appear after the age of 50 years, often causing spontaneous bleeding and post-traumatic bleeding, and even appear.

Pyogenic granulomas.

and other complications. At the same time, patients with bright red nevus and their families have different degrees of psychological disorders, such as inferiority complex, poor social adaptability, and even affect further education, work and normal life in severe cases.

Also known as port-wine nevi or telangiectasia nevi, they often appear at birth or shortly after birth, and tend to occur on the face, neck, and scalp, and are mostly unilateral or occasionally bilateral, sometimes involving mucous membranes. The lesion begins as several pale red, dark red or purplish-red patches of different sizes, irregularly shaped, with clear borders, not high above the skin surface, capillary dilation, partial or complete discoloration of the pressure, and a smooth surface. As the color darkens, red, and purple with age, the lesion in 65 patients will gradually expand, thickening and nodules may appear before the age of 40 years, and bleeding is prone to after trauma.

Bright red nevus is a flattened plaque with few bulging dilated capillaries and is a congenital capillary malformation. The size of the lesion increases with the growth of the body and does not resolve for life.

Bright red nevi can occur in any area, but are more common on the face and neck, accounting for 75 80 people, and are more common on one side and on the right side. When a bright red nevus involves both the ophthalmic nerve and the maxillary nerve, there is a 15% chance that it can be combined with refractory glaucoma.
