How the red birthmark on the baby s body is formed

Red birthmark is vascular disease, which will grow progressively throughout life except for neonatal erythema. Birthmarks on the face and neck will not only damage the appearance, but also affect the normal development of nearby organs.

1. Causes of Red Birthmark During 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 a red birthmark.

2. The cause of red birthmark is observed to be higher in girls than in boys, and the level of estradiol is increased in the hemangioma tissue, which is a type of estrogen in the human body, indicating that it is related to the level of estrogen.

3. The cause of the formation of red birthmarks is due to the lack of nerves innervating the blood vessels at the lesion site, which makes the capillaries dilate and congested, which appear as red or pink patches at first, and then deepen with age, become bright red and purple, and can be thickened and nodular.

A red birthmark is a bright red spot nevus commonly known as a capillary hemangioma in medicine. The pigment cells that cause red birthmarks are due to the severe deficiency of trace elements such as zinc, copper, calcium, magnesium and phenylalanine and tyrosine in the serum, which affects the biochemical process of pigment synthesis, resulting in an abnormal increase in pigment secretion by pigment cells, which gradually spreads through the epidermis through nerve transmission and forms plaques. But the red birthmark with neat edges spreads more slowly.

Bright red nevi in babies, also known as wine-colored nevi and flame-colored nevi, also known as baby red birthmarks, can generally appear at birth or shortly after birth. If you don't see a trace within a few months of birth, it usually doesn't happen again.

Baby's bright red nevus is a benign congenital vascular lesion, its incidence is about, manifested as one or several clear boundaries of light red or lilac red plaques, the size of the variety, at first generally not high above the plane, if not ** to the elderly, may be nodular hyperplasia, pressure is easy to fade, most of the damage is seen in the face, the color can change to a certain extent, when crying, when straining or when the bath is hot, the color may be deepened.

Types of Birthmarks and Diagnosis Birthmarks, medically known as mother spots or moles, are abnormal growths of ** tissue as they develop.

A red birthmark is a birthmark that is often present at birth, and is generally dark red, orange, and dark purple. It has a fairly high incidence rate, and the main areas of growth are the face and neck. Generally, it does not invade the surrounding healthy tissues, mostly occurs in the surface layer and does not protrude**, and can fade when pressed.

What should I do if I have a red birthmark? "Red birthmark" is the common name of bright red nevus, also known as wine stain, which is a congenital progressive vascular malformation involving capillaries and postcapillary venules in human beings, and is also the most common**vascular malformation, the incidence in newborns is to, generally occurs in the face, neck, especially the area where the maxillary branch of the trigeminal nerve and the eye branch are located, will expand in proportion to the growth of age and **, how big the red spot will grow, and the color of the lesion will change from pink to dark red, and then to purple red, Small purplish-red nodules may grow at the site of the lesion, enlarged and prone to bleeding. The change in lesion color is due to an increase in haemoglobin due to dilation of capillaries and retrocapillary veins in the affected area.

What should I do if I have a red birthmark? According to the color of the lesion, the degree of thickening, and the formation of nodules, bright red nevi can be divided into three types: pink type: the lesion is flat and has no bulge, the same as normal**; The color is light red to deep red, and the acupressure is completely faded.

Purple-red type: the lesion is flat and without bulge, the same as normal**; The color is light purple to dark purple, and the color may or may not fade completely under acupressure. Thickened:

The lesion is thickened and higher than normal**, there is nodular hyperplasia, the color is dark purple, and the acupressure is incomplete or non-fading.

According to the color of the lesion, the degree of thickening, and the formation of nodules, bright red nevi can be divided into three types: pink type: the lesion is flat and has no bulge, the same as normal**; The color is light red to deep red, and the acupressure is completely faded. Fuchsia type:

The lesion is flat and non-bulging, the same as normal**; The color is light purple to dark purple, and the color may or may not fade completely under acupressure. Thickened type: the lesion is thickened higher than normal**, there is nodular hyperplasia, the color is dark purple, and the acupressure is incomplete or non-fading.

How do I get rid of a red birthmark?

After understanding the pathogenesis and manifestations of bright red spots, what should I do if I have a red birthmark on my body? Earlier, the traditional method of bright red nevus was non-selective, but it was eliminated due to complications such as obvious pigment changes in scars, until the advent of pulsed dye laser in 1983, and the first of bright red nevi had a revolutionary change, but this ** is mainly suitable for**most Caucasian people's bright red nevus, and yellow people's ** compared with Caucasians, the absorption of light is stronger, and it is more likely to produce damage to the ** structures around the blood vessels.

In the 90s of the 20th century, photodynamic power was applied to bright red nevi in China, and good curative effect was achieved. Photodynamic** is a highly selective drug-device combination technique that involves two steps: drug administration (photosensitizer such as hemporfin) and illumination. Taking hemporfin photodynamics as an example, after the photosensitizing drug is injected into the human body through intravenous injection, it is quickly absorbed and enriched by the vascular endothelial cells that make up the blood vessel wall, and the cells in the epidermal layer absorb very little, and then give a specific wavelength light source that can penetrate the epidermis and can be selectively absorbed. So as to achieve the purpose of dilating the malformed capillary network by targeted destruction.

Yes, the harm of red birthmarks can be divided into four aspects.

1.The area is enlarged, which affects the aesthetics.

The red birthmark will become larger and thicker with the age of the patient, and the depth of the lesion will become deeper and deeper, and the serious can be the patient's crooked mouth and slanted face, which is extremely harmful to the patient's appearance.

2.Ulceration and infection, bleeding does not stop.

Red birthmarks, also known as microvenous malformations, often break and bleed after rubbing or scratching because they occur on the surface, and the bleeding does not stop for a long time after bleeding. Tumors that break down can easily become infected and ulcerated, which can lead to scarring.

3.Mental torture, psychological disorders.

Red birthmarks mostly occur on the face, neck and other obvious places, which will cause patients to have low self-esteem and be mentally tormented.

4.Destruction of organs, with a lifetime.

Birthmarks can occur anywhere but are more common on the face, more on one side and more often on the right side. If the red birthmark grows on more than two-thirds of the face, pay attention to the occurrence of glaucoma and epilepsy, and when the red birthmark affects both the ophthalmic nerve and the jaw nerve, there is a partial chance of refractory glaucoma.

Hello, birthmarks are generally caused by **pigment abnormalities or **vascular abnormalities, mainly including "spots", "moles", and "hemangiomas". Birthmarks can be found at birth or may not appear until a few months after birth.

The red birthmark will gradually increase in size with age, and the color will become darker and darker, and the lesion will gradually deepen. The area of the red birthmark will become larger and larger, which may not only have a serious impact on the patient's aesthetics, but also cause the patient to have a bad psychology and bring a serious psychological burden. Birthmarks can be used, there are many ways to have birthmarks, it is recommended to go to the hospital for further examination, clear diagnosis of birthmark type, according to the specific situation, symptomatic**.

It can be removed by **, the red birthmark can deepen the color of the erythema with age, the area increases, and there can be nodules or wart-like hyperplasia on the surface, and the histopathology of the red birthmark can mainly be manifested as abnormal dilation of capillaries in the dermis, weak tube wall, and hyperplasia of intradermal tissues. Red birthmarks usually appear as light red or purplish-red patches, not prominent**, with a flat surface, irregular appearance of fading pressure, mostly occurring on the face, neck, scalp, etc., and can also be found in other parts of the body such as upper and lower limbs, front chest or back of hands.

Hello, as you describe is a bright red spotted mole, about 1 in 3 newborns will have this birthmark, as the child grows older, most of them will gradually disappear. After that, there is a cavernous hemangioma, which often appears under the skin of the head or neck in Tongyou, if it grows deeper, the ** covered by the upper grinding surface looks the same, and will disappear before puberty.
