What are the common types of vitiligo?

Vitiligo is a common disease.

There are two types of common types in clinical practice, vitiligo vulgaris and segmental vitiligo. Different types of vitiligo must be used in different ways, experts pointed out that identifying the type of vitiligo is the first step of vitiligo, and it is extremely important for vitiligo.

Vitiligo classification: Vitiligo vulgaris.

Generalized vitiligo:

Generalized vitiligo is mostly sporadic, and vitiligo mostly merges into irregular large patches that cover most of the body, sometimes leaving only small islands of normal skin color.

Localized vitiligo: Vitiligo varies in size and is isolated or distributed in groups on one part of the body.

Sporadic vitiligo: refers to vitiligo that is scattered, multiple, and often symmetrically distributed, with a total area of no more than 50% of the body surface area.

Acral vitiligo: Vitiligo initially occurs in the extremities of the human body, such as the face, hands, feet, fingers and other exposed parts, and is mainly distributed in these parts, and a few can be accompanied by generalized vitiligo of the body.

Vitiligo is classified as segmental vitiligo.

The segmental type, also known as the hemilateral type, is a relatively difficult form of vitiligo. It generally follows the distribution of one nerve and produces continuous vitiligo. It is generally believed that the pathogenesis of segmental vitiligo is mainly caused by neurological factors, and it is basically difficult to treat it in a timely manner except for early treatment.

The above is some knowledge of the common types of vitiligo. Having vitiligo is not the most terrible, the most terrible thing is that we are not able to get it right. This is the reason why many patients with vitiligo do not heal for a long time.

Jinan Xijing Thundering Answer: 1, limited type 2, sporadic type 3, widespread type 4, segmental type.

Vitiligo is clinically divided into two stages, advanced and stable. The so-called advanced stage refers to the continuous expansion of skin lesions, and there are new skin lesions, and the homomorphic reaction is positive (that is, the formation of new white spots on the basis of trauma or other ** diseases). The stable phase is when the lesion no longer expands and there are no new lesions.

One. Vulgar:

1) Sporadic type: scattered multiple leukoplakia, of different sizes, can occur in any part of the body, but multisymmetrically distributed, the total area does not exceed 50 of the body surface area. This is one of the types of vitiligo.

2) Localized type: single or cluster of vitiligo of different sizes confined to a certain site.

3) Generalized type: vitiligo exceeds more than 50 of the total area of the body surface, and even affects the whole body, with only a few or no normal pigment**, which is generally believed to be related to autoimmune abnormalities, and is mostly developed from the first two types.

4) Acral type: This is also a type of vitiligo, vitiligo is mainly distributed in the exposed parts of the hands, feet, fingers, toes, head and face at the beginning of the episode, and a few can be accompanied by generalized vitiligo on the body.

Two. Segmental type: leukoplakia is one or several patches, distributed along the ** area innervated by a certain cutaneous nerve segment, generally unilateral, more common in children.

Vitiligo is a common and frequent disease in our daily life. Based on the clinician's diagnosis over many years, vitiligo can be classified into two types: vulgar and segmental.

Among them, the main manifestation of the segmental type is one or several white patches, which are distributed along the ** area innervated by a certain cutaneous nerve segment, and are generally unilateral.

Vitiligo vulgaris is divided into four types according to the shape, location, scope and reaction of vitiligo

1. Limitations: single or cluster leukoplakia, of different sizes, confined to a certain part.

2. Sporadic: scattered and multiple leukoplakia, often symmetrically distributed, and the total area of leukoplakia does not exceed 50% of the body surface area.

3. Generalization: mostly developed from sporadic, most of the white spots are fused into irregular large patches involving more than 50% of the body surface area, and sometimes only small island-like normal skin color remains.

4. Acrality: Acral leukoplakia initially occurs in the extremities of the human body, such as the face, hands, feet, fingers and toes, and is mainly distributed in these parts, and a few can be accompanied by generalized leukoplakia on the body.

Vitiligo is divided into type II, type II, and stage II. (1) Type 2 Vulgaris and segmental type 1. Vulgar type: divided into localized, sporadic, widespread and acral.

1) Limitations: single or clusters of vitiligo of different sizes confined to a certain site. (2) Sporadic:

Scattered multiple leukoplakia that can occur anywhere around the body, with a total area of no more than 50 percent of the body surface area. 3) Generalized type: vitiligo exceeds more than 50 of the total area of the body surface, and is mostly developed from long-term diseases.

4) Acral: Vitiligo is mainly distributed on the hands, feet, fingers, toes, head and face. 2. Segmental type:

Leukoplakia runs along the ** region of a certain cutaneous nerve segment and is generally unilateral. (2) Class II Complete leukoplakia and incomplete leukoplakia 1. Complete leukoplakia: pure white or porcelain white, melanin disappears in the leukoplakia area, and there is no pigment regeneration.

2. Incomplete vitiligo: melanocytes are reduced in the vitiligo area, because there are still some melanocytes, and melanin spots can be seen in the vitiligo area. (3) Phase II Progression and Stability 1. Progression:

The white spots gradually increased, and the original white spots gradually migrated and expanded to normal**, and the realm was blurred. 2. Stable period: the vitiligo stops developing, the boundary is clear, and there is a deepening of melanin on the edge of the vitiligo.

Hello! Vitiligo is generally divided into vitiligo vulgaris and segmental vitiligo, and vitiligo vulgaris includes localized, generalized, sporadic, and acral types.

Vitiligo is not as terrible as the patient thinks, find a professional hospital, as long as the doctor is fully responsible for the patient, in the case of ensuring the efficacy, minimize the cost, as long as the patient is in line with the principle of active cooperation, vitiligo is not terrible. Generally, it can be effective in two months, and two to four courses of treatment can achieve the goal of clinical cure.

Stages: germination, progression, stability, **, consolidation.

Classification: localized, sporadic, generalized, localized, follicular

Color separation: pale white, milky white, cloud white, porcelain white.

Having vitiligo is not necessarily vitiligo, Nanchang Vitiligo Hospital recommends that it is best to go for examination and identification, pay more attention to rest, and do not stay up late.

1.Localized: Focal one or more leukoplakias confined to one area but not segmental; Unilateral (segmental) One or more white patches are segmental and disappear abruptly at the midline; Mucosal involves only the mucosa.

2.scattered common form extensive and scattered white patches; Facial acral type is distributed on the face and limbs; Mixed segmental, facial acral, and/or vulgar mixed distribution.

3.Generalized: total or almost total depigmentation.

More than 90% of vitiligo is scattered, and the remaining vitiligo is more localized than generalized. According to the depigmentation of the lesions, the disease can be divided into complete and incomplete types. The former has a negative response to dihydroxyphenopalanine (DOPA), the melanocytes disappear, and the response is poor.

The latter is positive for DOPA, and the melanocytes do not disappear but the number decreases, and the chances are high.

Guidance:

Vitiligo is a stubborn disease, but it is not uncontrollable. As long as you avoid exposure to environmental triggers, you can achieve good results by accepting reasonable ** as early as possible and actively cooperating with doctors to carry out correct **.

The manifestation of localized vitiligo is mainly that the white patches are confined to one place, which can be one or several patches. This type of vitiligo occurs in no fixed area, and white patches can be found anywhere on the body. If it is in the advanced stage, the leukoplakia is limited to one place, but the area will continue to expand.

The incidence of this type of vitiligo is closely related to traumatic factors, and clinical observation has found that a considerable number of localized vitiligo lesions have had different degrees of trauma, and vitiligo is very prone to isotype reactions. The manifestations of localized vitiligo cannot be ignored, and it cannot be considered that it is only confined to that one place, and if it is not properly cared for, it is likely to turn into generalized vitiligo.

This symptom of sporadic vitiligo is the main differentiator from generalized vitiligo. Many patients with vitiligo believe that the main manifestation of vitiligo is that the white patches are distributed in multiple parts that are generalized, but in fact, it is not, as long as the total area does not exceed 50%, it is sporadic vitiligo. However, as sporadic vitiligo worsens, the area of vitiligo expands, and once it exceeds 50%, it means that sporadic vitiligo has developed into generalized vitiligo.

In the early stage of vitiligo, the degree of depigmentation of vitiligo is light, and the boundary between 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 vitiligo is smooth and no dandruff, vitiligo is pale white or milky white, if the boundary is blurred or spread towards the normal **, it may be vitiligo, vitiligo often manifests mainly with the following symptoms: 1. There is no itching, even if there is a very slight feeling. 2. The number of depigmented spots is small, generally only 1-2 pieces, and most of them appear on the exposed parts.

3. Except for depigmentation, the ** at the depigmented spot is the same as the surrounding **, there is no itching, desquamation or atrophy and other changes. 4. Early vitiligo should be considered first when there are no other ** diseases.

Vitiligo can be divided into two types, namely the vulgar type and the segmental type.

1. Vulgar type: Vulgar type is divided into localized, sporadic, generalized and acral facial.

Localized leukoplakia: Leukoplakia varies in size and is isolated or distributed in groups on one part of the body.

Sporadic leukoplakia: refers to the sporadic and multiple, often symmetrical distribution, which can occur anywhere on the body, and its total area does not exceed 50% of the body surface area.

Generalized leukoplakia: Generalized leukoplakia is mostly developed from the above two types, and most of the vitiligo is fused into irregular large patches with each other, covering most of the body surface, which is generally believed to be related to autoimmune abnormalities.

Acral leukoplakia: Leukoplakia initially occurs on the extremities of the human body, such as the face, hands, feet, fingers, toes, head and face and other exposed parts, and a few can be accompanied by generalized leukoplakia on the body.

2. Segmental type (also known as hemilateral type): leukoplakia is one or several patches, which are distributed along the ** area innervated by a certain cutaneous nerve segment, which is generally unilateral and is more common in children.

1. Sporadic vitiligo. The main symptom of this type of vitiligo is that a large number of white spots appear on the patient's body, and the area of white spots exceeds 50%, which has a great impact on the appearance of the patient.

2. Localized vitiligo. This type of vitiligo is mainly confined to one place, and can be one or several patches. It can occur anywhere in the body.

As the disease progresses, the area of vitiligo vitiligo vitiligo continues to expand. It can develop into generalized vitiligo, which seriously affects the patient's appearance and makes the patient miserable.

3. Generalized vitiligo. The white spots of generalized vitiligo can involve multiple parts of the patient, and are distributed in patches, irregular shape, and generally it is symmetrically distributed, generalized vitiligo often has severe damage to melanocytes, and accumulates to the eyebrows, head and other parts, resulting in gray hair, which needs to be paid attention to.

Hello, the classification of vitiligo, 1. Localized, vitiligo is only confined to a certain part. 2. Vulgar type, multi-symmetrical distribution of white spots. 3. Acral type, mainly at the end of the limbs, is easy to spread to the face.

4. Segmental type, the distribution of leukoplakia along the innervation of a certain nerve segment. 5. Hair follicle type, hair, eyebrows, beard, etc. become white.

Hello span, it is very important to find out the symptoms of vitiligo**, vitiligo ** has improper diet, insufficient trace elements, trauma, genetics, endocrine disorders, low immunity, sun exposure, lack of energy, etc. /span

Patients with vitiligo should pay attention to understanding more about vitiligo, choose the appropriate method according to the color of vitiligo, the period of the disease, the type of disease, and the combination of personal physique, do a good job of self-care, abide by the doctor's instructions, strive to control the condition, and achieve good results. /span

It is recommended that patients choose a regular vitiligo hospital**, **vitiligo is mainly for different**, symptomatic**, it is recommended that patients do not blindly use drugs**, and need to actively cooperate with doctors, which is good for vitiligo**. The above is a suggestion on what types of vitiligo can be roughly divided into, I hope it will be helpful to you, and I wish you good health!

Leukoplakia: The boundary between vitiligo and normal ** is clear, pure white or porcelain white, the hair in the vitiligo has turned white or most of it has turned white, and there is no pigment regeneration. Melanocytes disappear in the vitiligo tissue and are negative for dihydroxyphenylalanine (dopa).

1. Limitations: single or cluster leukoplakia, of different sizes, confined to a certain part.

2. Sporadic: scattered and multiple leukoplakia, often symmetrically distributed, and the total area of leukoplakia does not exceed 50% of the body surface area.

3) Generalization: It is mostly developed from sporadic, and the white spots mostly merge into irregular large patches and involve more than 50% of the body surface area, sometimes only small island-like normal skin color remains.

4) Acral disease: vitiligo initially occurs on the extremities of the human body, such as the face, hands, feet, fingers and toes, and is mainly distributed in these parts, and a few can be accompanied by generalized leukoplakia on the body.
