How are bright red spots caused? What should I pay attention to?

The ** formed by bright red nevus has the following points: 1. Due to the lack of nerves innervating the blood vessels at the lesion site, the red birthmark formed by telangiectasia is caused. 2. In the process of embryonic development, especially in the early stage of vascular tissue differentiation, due to the small range of misartery in its control gene segment, the local tissue differentiation is abnormally formed.

3. According to the incidence of bright red nevus in girls is higher than that in boys, the level of estradiol is found to be increased in the tissue of this bright red nevus, so estradiol can also cause bright red nevus. 4. According to the occurrence and growth trend of bright red spots, environmental pollution, and other external environment-related reasons. 5. Genetic factors, in the people who appear in bright red spots, usually occur when the baby is born, so the analysis of bright red spots is also related to genetic factors.

6. It may be related to the bad habits of pregnant women during pregnancy, especially taking drugs. Therefore, different birthmarks are formed for different reasons according to their color and growth.

The cause of the formation of bright red nevi.

According to research, the microvenous vascular malformation of bright red nevus is caused by a genetic mutation. The causes of gene mutations are related to factors such as diet, environment, and genetic inheritance.

The details are as follows. 1. In the process of embryonic development, especially in the early stage of vascular tissue differentiation, due to the small-scale misformation of its control gene segment, the tissue differentiation of specific parts of the embryo is abnormal, and it develops into bright red nevus.

2. Among the patients with bright red nevus, the incidence of girls is higher than that of boys, and doctors have detected an increase in the level of estradiol (estradiol is a kind of estrogen in the human body) in the hemangioma tissue, indicating that the level of estrogen is related to the level of bright red nevus.

3. Food pollution and environmental pollution are also the causes of bright red spots in the human body to a certain extent. Many contaminated foods contain chemicals that are harmful to humans. If people consume these things for a long time, they are prone to vascular abnormalities, which leads to the appearance of bright red spots.

Bright red spot nevus is a kind of birthmark, and there are many reasons for bright red spot nevus, the main reasons are:1Genetic causes:

It has a certain relationship with heredity, but the probability is very small, and it is very rare in clinical practice2Congenital malformations of development: due to the malformation of capillaries during development, they invade and compress adjacent parts and do not resolve on their own3

Effect of telangiectasia and congestion: due to the lack of innervation of vascular nerves, the blood vessels of the annunciation undergo a certain degree of dilation and congestion, which is pink at first, and with the increase of age, the color is aggravated, dark red, dark purple.

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.

This problem is caused by viral infections and dilated blood vessels

Bright red nevus is recommended to be observed before the age of 2, and it is better to wait for it to disappear after the age of 2.

If the bright red nevus will not disappear on its own, it is recommended to go to the local regular hemangioma specialist hospital for treatment as soon as possible to prevent gradual spread, and formulate a plan under the guidance of the doctor.

The cause of bright erythematous nevi is the lack of nerve innervating the blood vessels at the lesion site, which causes the capillaries to dilate and congest, which initially appear as red or pink patches, which can later deepen with age, become bright red and purple, and may thicken into nodules.

It may be only a small red spot after a few weeks of birth, and then the area gradually expands, highlighting the normal** surface, bright red, uneven surface, similar to strawberry, hence the name. Strawberry-like capillary hemangioma can be seen in all parts of the body, the area is different, some growth rate exceeds the growth and development of children, the surface of the hemangioma is prone to ulcers and causes more bleeding, the wound is difficult to heal, and the scar is left after healing.

Bright red nevi, also known as port-wine nevi or telangiectasia nevi, often appear at birth or shortly after birth, tend to occur on the face, neck, and scalp, and are mostly unilateral, occasionally bilateral, and sometimes involve 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. With age, the color darkens, reddens, and purple, and in 65% of patients, the lesion will gradually expand, thickening before the age of 40, nodules appear, and bleeding easily after trauma.

Experts from the Laser ** Center of the Second Hospital of the Beijing Armed Police pointed out that bright red nevi, also known as wine-like nevus or telangiectasia nevus, appear at birth and tend to occur on the face and neck, mostly unilateral, occasionally bilateral, and sometimes involve the mucosa. Hazards of bright red nevus:1

With the increase of age, the area is getting larger and larger, the color is getting darker and darker, and the depth of the lesion is getting deeper and deeper, which causes more and more difficulty to **, and there are many superstitious elderly people who say that the birthmark is the placenta and is God's will. Growing in some parts is still a symbol of promotion and wealth, which cannot be removed by artificial means, or some places have relatively backward medical conditions, and there is no good way, so that the child can only accept it when he is older, because the local ** will bring some pain to the child, and the child is worried that the child will not be able to bear it, they do not take into account the harm of the bright red nevus, and the area of the bright red nevus will become larger and larger, and they will not be promoted or made rich because of this birthmark, but because the birthmark has an impact on the appearance and makes it difficult to find employment. 2.

Bleeding we all know that bright red nevus is caused by vascular malformation, because it occurs in the epidermis and dermis, so it is often subject to friction or scratching after breaking and bleeding, especially in summer, due to the hot weather, after sweating, ** itching, bright red nevus is often scratched resulting in a lot of bleeding, not only for a long time, and the harm of bright red nevus after breaking and bleeding is easy to infect, causing trouble and burden to patients or children's parent care. The syndrome of bright red nevi that grows on more than two-thirds of the face should be associated with the occurrence of glaucoma and epilepsy. Bright erythematous nevi can occur anywhere, but are more common on the face and neck, accounting for 75% to 80%, and are more common on one side and on the right side.

Bright red nevi have a 15% chance of being associated with refractory glaucoma if both the ophthalmic nerve and maxillary nerve are involved. In 1% to 2% of patients with bright erythematous nevi, there is an ipsilateral leptomeningeal vascular malformation, called Sturge-Weber syndrome. Usually sporadic cases.

A purplish-red facial nevus in the distribution of the trigeminal nerve in the face, present at birth, is a diagnostic sign. The first neurological symptom is usually localized epilepsy on the contralateral side of the facial lesion. There may be mental decline, contralateral hemianopia, hemiparesis of the contralateral limb, atrophy, and growth lag of the unaffected limb.

There may be a bulging eye on the same side of the mole, glaucoma, bull's eye, or optic atrophy. There can also be wine-colored nevi on other parts of the body, with hemangiomas such as retina, kidney, and liver. It can also be accompanied by cryptorchidism, spina bifida, syringomyelia, etc.

Can be life-threatening due to intracranial hemorrhage or status epilepticus. Warm reminder from the Laser ** Center of the Second Academy of the Beijing Armed Police: The above is the relevant knowledge of "" is introduced here, I hope it will be helpful to you.
