What are the manifestations of vitiligo during the spread period, and what symptoms will appear afte

First, observe the edges of the original white patches. In general, the edges of the vitiligo are blurred and tend to spread towards normal**, which is most noticeable.

Second, observe the color of the vitiligo. In general, in the early stage of vitiligo spread, the white patches will gradually darken in color, and this is often easy to be overlooked by patients, especially those who develop in unexposed areas. Generally speaking, in the early stage of vitiligo spread, the white patches will appear pale white and blurry-like changes, and the darker the white spots, the more serious the loss of black cells in the epidermis and subcutaneous tissues, and the lighter the white spots, the better the effect, so vitiligo patients must hurry up at this time, because if this development continues, the difficulty will increase.

In addition, it is necessary to observe the extent of the white patches. Another condition in which vitiligo spreads is vitiligo metastasis, which is usually white patches that have spread if the person notices new white patches in other parts of the body.

Jinan Xijing Liang Wanbing: "The degree of decolorization is light, and the boundary with the surrounding normal ** is blurred, if this situation occurs in **whiter people, it is often difficult to diagnose in time, carefully observe whether the surface of the white spots is smooth without dandruff, the white spots are pale white or milky white, and the boundaries are blurred or spread towards the normal." ”

Vitiligo can be divided into three stages according to the severity of the disease:

1. Early manifestations of vitiligo: white patches are milky white or white. The shape is nearly round, oval, or irregular. Some margins are wound with bands of pigment. Some new leukoplakia has a slightly arched inflammatory dark red strip on the margin.

2. Manifestations of vitiligo in the middle stage: vitiligo patients in the middle of the disease, the surrounding cities of the disease site, a depigmented ring, its color hand sail color is slightly darker than the white spots, lighter than the normal skin color, the dispersion ring is intact ring, the white spots on the margins of the dispersed ring are striped, and the state potato heng is scattered in the shape of rays to the surrounding skin.

3. Manifestations of advanced vitiligo: The white book spots on patients with advanced vitiligo are usually in the shape of a map. The white patches have ceased to develop, the number and area have ceased to increase, and the color of the white patches has gradually deepened, and the boundary with the surrounding skin has become clear, making it easy to identify.

The white spots appear porcelain-white in color, and the melanocytes are simply lost.

In the early stage of vitiligo patients, due to the light color of the white spots, some of which cannot even be distinguished by the naked eye, the patient will not notice too much, but the boundary with the normal ** is not obvious.

In the middle and late stages of vitiligo, the pigment at the edge of the lesion will be significantly deepened, which is in sharp contrast with the surrounding normal **, and the white patches are very obvious. When the white spots darken, they usually turn cloud-white or porcelain-white, which is a sign of worsening vitiligo symptoms.

As the damage to melanocytes in the lesion becomes more severe, the synthesis of melanin decreases, and the vitiligo will develop from pale white or milky white to a darker cloud white or porcelain white. If the symptoms of vitiligo are aggravated, the white patches on the affected area of the patient will generally be connected.

Hello, vitiligo is a common acquired localized or generalized** depigmentation disease. Caused by the loss of melanocyte function of **; It appears as a porcelain-white depigmented patch that is milky white in color, and scattered island-like pigmented areas around the pores may appear in the white patches. The initial symptoms are that the surface of the vitiligo is smooth and flakes-free, the degree of discoloration of the vitiligo is mild, the boundary between the vitiligo and the surrounding normal ** is blurred, and there is a tendency to spread towards the normal**, and there are generally no conscious symptoms.

If there is a spread, the area will become larger, the edges will become blurred, and there is a tendency to spread gradually.

1. Vitiligo develops from a single patch: vitiligo is a diffuse disease, and the spread rate is relatively fast, if the vitiligo spreads, then it means that the condition is aggravated. This is where the symptoms can also vary.

At first, there are only a few scattered white patches, and when the disease gradually worsens, the white patches in the affected area are usually connected together. Under normal circumstances, in the early stage of vitiligo, the common distribution state of white patches on the patient's body is a single existence, and in the middle and late stages of vitiligo, the white patches will gradually join one piece, and the adjacent white spots will slowly merge together, and even spread to all parts of the body.

2. The color of vitiligo is deepened and very obvious: the color of vitiligo vitiligo will be different at different stages, and the color of vitiligo will be lighter when the disease is mild, and the color of vitiligo will be darker on the contrary. This also reflects the degree of loss of melanin in the affected area at different times.

In the early stage of vitiligo, the color of vitiligo is generally light, and some white spots can not even be distinguished with the naked eye, and the boundary between normal and normal is not obvious, but in the later stage of vitiligo, the pigment on the edge of the lesion will be significantly deepened, in sharp contrast with the surrounding normal**.

3. The area of skin lesions increases, and the white spots cover many places on the body: vitiligo spreads, and it is difficult to control the white spots after the aggravation of the disease, and the area of white spots will also increase at this time. This symptom is mainly a symptom of the later stage of generalized vitiligo, and the white patches cover more than half of the total area of the body and are distributed in multiple parts of the body, which is more difficult.

Features of vitiligo diffusion:

1.The diffusion ring is a common marker during the spread of vitiligo. This ring can be further depigmented relatively quickly and completely blended into the white patches, so that the white spots will gradually expand. After that, a spreading halo continues to appear around the enlarged white patches, and the white spots continue to expand over and over again.

2.Strips of white patches with outward tips around the white patches are usually made up of thin white patches. The boundary of diffusion rays can be clear, but most of them are not very clear, Hua Hai said that the atypical ones are acutely angled triangles, and their acute angles point to normal**, the longer its radiation, the longer the speed of diffusion.

3.Around the vitiligo lesions, there is a depigmentation ring, which is slightly darker than the vitiligo and lighter than the normal skin tone, and the edge of this diffusion ring may be clear or indistinct, but it is a complete ring, and some depigmentation zones may appear around it. This diffuse halo is present in the white patches and in the middle of the normal **, slowly spreading, and this halo or diffusion band can be wide or narrow.

There are many factors that cause the onset of vitiligo, which can only be determined after a special instrument examination. If the surface of the vitiligo is smooth, does not flaky, and is not painful or itchy, it is generally considered that vitiligo is more likely. The biggest feature of vitiligo is that it is easy to develop, and it is recommended that patients should develop as soon as possible, so as not to delay the condition and miss the best time.
