What is the difference between vitiligo and insect spots?

Pityriasis alba, also known as simple pityriasis vulgaris, is commonly known as insect spots, and its ** is not clear. Some scholars believe that it is related to bacterial, viral, and parasitic infections, so some people call it insect spots. At present, it is considered to be a non-specific dermatitis, which is related to malnutrition, vitamin deficiency, dryness and sun exposure.

Insect spotting is a common disease in children, and it can also occur in young adults. There is no gender difference, it has a certain relationship with the season, and most of them start in spring and subside after summer and autumn. Lesions are single or multiple, mostly on the face but also on the upper arms, neck, and shoulders.

Hypopigmentation is round or oval, the boundary is clear, the edge is slightly raised, covered with a small number of small scales, mostly without conscious symptoms, the size of the patches is different, about 1 cm to several centimeters in diameter, the early is light red, and soon becomes light white, at this time, if you do not pay attention to identification, it is easy to be confused with vitiligo. However, incomplete depigmentation of the subtractive spots, rough surfaces, and sometimes scales are helpful in differentiating from localized vitiligo. The disease is usually asymptomatic and some patients may have mild itching that resolves spontaneously over a few months or longer, which is also different from vitiligo.

Recently, some netizens consulted: Last month, my child had a white spot on his face, he said it didn't hurt or itch, and I didn't care much, but half a month has passed, the white spots are still there, and an uncle in the neighborhood said that it may be pediatric white spots, but it also looks a bit like the symptoms of vitiligo, we don't know what the disease is, I want to ask experts what are the differences between the symptoms of vitiligo and pediatric insect spots? In fact, this kind of problem is not once or twice, many parents will have such a reaction, let the authoritative expert on vitiligo give you a detailed introduction.

The symptoms of vitiligo are characterized by the appearance of white patches, generally white patches are porcelain white, and the size and shape are different, the boundary is clear, there is increased pigmentation at the edges, there are no conscious symptoms, after sun exposure, it is easy to appear erythema, even blisters, there will be burning, inflammation, and then the white spots will be larger than the primary range, and the skin lesions can occur in any part. Leukoplakia is often symmetrical or unilateral, or even banded along the nerve. The first symptom of insect spots is manifested as hypopigmentation is round or oval, the boundary is clear, the edge is slightly raised, covered with a small number of small scales, and most of them are characterized by unconscious symptoms, the size of the patches is different, about one centimeter or several centimeters in diameter, the early stage is light red, and soon it becomes light white, at this time, if you do not pay attention to identification, it is easy to be confused with vitiligo.

Vitiligo and pediatric vitiligo are easily confused, and from the above, we cannot find that the most important difference between insect spots and pediatric vitiligo is that the subtractive spots of insect spots are incomplete depigmentation, rough surface, and sometimes scales, while vitiligo has a smooth surface without flakes. In short, it is not what kind of disease the child has, but it must be carried out in a regular hospital in time, so as not to miss the best time. In the past, vitiligo was broadly defined as an acquired hypopigmented disease, in fact, more specifically, it is due to the insufficient supply of melanin in the circulatory system of subcutaneous cells in a certain part of the body, resulting in depigmentation of the epidermis**, and depigmentation to a certain extent, it forms vitiligo.

The above is the relevant content about vitiligo explained by experts, I hope it will be helpful to patients. At the same time, experts still recommend that patients usually develop good living habits, pay attention to personal hygiene, and pay attention to the protection of the best, especially children, in the cold winter, because they are too naughty and ignore the protection of the best. I hope parents will pay more attention.

Help children get sick early and give them a good childhood.

It is recommended that you go to a regular hospital for vitiligo diagnosis and medical treatment, so that the regular hospital can confirm whether it is vitiligo and the cause of the disease. And the experts are also relatively experienced. The main differences between vitiligo and pityriasis alba are:

First, the symptoms are different. Vitiligo appears as pure white patches, even the middle hair can also turn white, the color is more obvious, the border is clear, the border is pigmented, the surface is smooth and the white patches are smooth and scale-free, and the white spots are white. Pityriasis alba typically presents as hypopigmented, round or oval patches of varying size, well-defined, slightly raised at the edges, and covered with a small number of fine scales.

There are usually no symptoms, but some patients may have mild pruritus. Second, the location of the disease is different. There is no certain area where vitiligo occurs.

White patches can occur anywhere. However, the face, neck, back of hands and other exposed parts, as well as the parts that are susceptible to compression and friction; Such as the belt and the joints of the limbs. Pityriasis alba usually occurs on the face, but can also be seen on the upper arms, neck, shoulders, etc.

Third, the pathological changes are different. Vitiligo is formed when melanocytes decrease or disappear. White is pityriasis acanthosis hypertrophy, mild edema, moderate keratotic transition and patchy parakeratosis, and decreased melanin.

Hope it helps.
