What s the deal with the white patch on the arm?

Hello: first observe whether the surface of the vitiligo is smooth and flaky, whether it still maintains a normal structure, and then pay attention to whether there is itching and other discomfort in the affected area, if there is no itching, the surface of the vitiligo does not have any dandruff, and the structure of the vitiligo is very complete, these are the most obvious symptoms of vitiligo, then at this time it can be preliminarily determined to be vitiligo, it is recommended that you go to a regular vitiligo hospital to use the instrument to detect and accurately diagnose the condition.

The symptoms of vitiligo are not complicated at the onset of vitiligo, and there is no feeling of discomfort at the onset of vitiligo. The main symptom is to ** vitiligo. Moreover, the number of leukoplakia is indefinite, it can be confined to a certain part of the body or distributed in a certain nerve segment (or dermatome), and the leukoplakia is mostly the size of a nail to a coin, nearly round, oval or irregularly shaped.

2.Some vitiligo has punctate hypochromic spots at the onset of vitiligo, and the realm is more obvious; Some of the edges are surrounded by pigment bands, except for depigmentation, there is no atrophy or desquamation in the affected area, and the hair on the white spots can lose pigment and even turn completely white, and there are also those whose hair remains unchanged for a long time.

3.Vitiligo white patches rarely disappear on their own. In most cases, the number tends to increase and enlarge gradually, and adjacent white patches can merge with each other to form irregular large patches that spread throughout the body.

Hope it helps, hope!

White spots on the arms are usually seen in the following:

1. After the child suffers from papular urticaria, the rash of papular urticaria subsides, leaving white punctate hypopigmented spots where the rash resides. Clause.

Second, the elderly appear white hypopigmented spots on the arms and lower limbs, which are generally not needed, and there is no obvious effect of medication. Clause.

3. White depigmented patches appear on the arms or other parts of the body, often seen in vitiligo. If you have white hypopigmented spots on your arms, but you can see slight scales on the surface, you can do a fungal test, and it may be a fungal cause of tinea versicolor.

Hello. This phenomenon is generally caused by extreme dryness and cannot be **. It is also associated with vitamin A deficiency, and vitamin AD pills can be taken appropriately. Generally, no special ** is required.

Suggestions: Eat more vegetables and fruits, you can also take vitamin E to relieve, or you can apply topical ointment under the guidance of a doctor.

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 flakes-free, and the vitiligo is pale white or milky white, if the boundary is blurred or spread towards the normal**, the possibility of vitiligo is considered to be relatively large. It is recommended that patients should go to a hospital specializing in vitiligo as soon as possible to check and diagnose it, so as not to delay the condition and miss the better time.

There are many types of vitiligo, you can carefully observe whether the surface of vitiligo is smooth and no dandruff, vitiligo is not painful or itchy, vitiligo is milky white or light white, if the boundary is blurred or develops towards normal, it is more likely to be vitiligo.

Is it piece by piece, if so, just go and check it out, so it's better, and you have to observe it yourself, which is also helpful for your condition.

It is recommended to go to the hospital for a check-up to see if it will be vitiligo, if it is diagnosed, it must be early, do not delay the best time.

Vitiligo is a relatively common acquired pigmented disease that manifests as a localized or generalized** complete loss of mucosal pigment. It is caused by the loss of melanocyte function, but the mechanism is not clear. It can occur in all parts of the body, and young women are the majority.

1.The doctrine of genetics.

Vitiligo can occur in twins and families, indicating that genetics plays an important role in the pathogenesis of vitiligo. Vitiligo has been suggested to have incomplete penetrance and multiple pathogenic loci in the gene.

2.Autoimmune Theory.

Vitiligo can be combined with autoimmune diseases, such as thyroid disease, diabetes, chronic adrenal insufficiency, pernicious anemia, rheumatoid arthritis, malignant melanoma, etc. Specific antibodies to various organs can also be detected in serum, such as anti-thyroid antibodies, anti-gastric parietal cell antibodies, anti-adrenal antibodies, anti-parathyroid antibodies, anti-smooth muscle antibodies, anti-melanocyte antibodies, etc.

3.Psychiatry and Neurochemistry Doctrine.

Psychiatric factors are closely related to the onset of vitiligo, and most patients have mental trauma, excessive tension, depression or depression at the onset or development stage of the lesion. Degeneration of nerve endings at the vitiligo also supports the theory of neurochemistry.

4.The theory of self-destruction of melanocytes.

People with vitiligo can produce antibodies and T lymphocytes, suggesting that the immune response may cause the destruction of melanocytes. The toxic melanin precursors synthesized by the cells themselves and some chemicals that cause ** decolorization may also have a selective destructive effect on melanocytes.

5.Lack of doctrine of trace elements.

In patients with vitiligo, the level of copper or ceruloplasmin in the blood and ** decreases, resulting in a decrease in tyrosinase activity, which affects the metabolism of melanin.

6.Other factors.

Vitiligo can also be induced by trauma, sun exposure, and some photosensitive drugs.

There is no significant difference in the gender of vitiligo, and it can occur in all age groups, but it is more common in adolescents. The lesions are depigmented patches, often milky white or light pink, with a smooth surface and no rash. The boundaries of the vitiligo are clear, the pigment at the margins is increased compared with normal**, and the hair in the vitiligo is normal or white.

Lesions are more likely to occur in areas of sun exposure and friction injury, and the lesions are mostly symmetrically distributed. Leukoplakia is also often arranged in bands according to the distribution of nerve segments. Vitiligo is often accompanied by other autoimmune diseases, such as diabetes, thyroid disease, adrenal insufficiency, scleroderma, atopic dermatitis, alopecia areata, etc.

Prevention 1Reduce the intake of contaminated food, correct picky eating, and formulate scientific dietary recipes.

2.Reduce the inhalation of harmful gases, and choose a place with fresh air during morning exercise or exercise.

3.Pay attention to labor protection.

4.Be aware of the pollution caused by the renovation of the house.

5.Keep a good mood.

If you find vitiligo, you should go to the hospital as soon as possible to identify whether it is vitiligo.

White spots on the body are not necessarily vitiligo, and white spots are divided into many conditions: vitiligo, albinism, sweat spots, tinea versicolor, pityriasis alba, etc. Vitiligo doesn't have to be vitiligo.

Carefully observe, whether the surface of the vitiligo is smooth and scaly-free, the border is more obvious than normal, there is a pigment band on the edge, the color of the vitiligo is lighter in the early stage of the disease, generally light white, the number of vitiligo is small, it can be single or multiple, the shape is irregular, the size is generally nails or coins, the sunlight is more obvious, if the sun is exposed for a long time, the vitiligo will be red, there may be a feeling of pain, and the above symptoms indicate that you have vitiligo.
