summary

The child told me that he had a lot of white patches on his body, which were not many before, but are becoming more and more serious now. He went to the dermatology department of the hospital to see the doctor, who said it was sweat spots or vitiligo, depending on the later changes. But we all need to take treatment. Next, I'll tell you what's the situation of white patches on your body?

What's the situation with white patches on your body

First: sweat spots, or the possibility of vitiligo, vitiligo disease is white spots or flakes, clear boundaries, smooth surface, no scales, no itching, the general naked eye is not diagnosed. Antibodies and T lymphocytes can be produced in patients with vitiligo, indicating that the immune response may lead to the destruction of melanocytes. The precursor of toxic melanin synthesized by cells themselves and some chemical substances that cause skin discoloration may also selectively destroy melanocytes.

Second: trace element deficiency theory, the level of copper or ceruloplasmin in the blood and skin of patients with vitiligo decreased, leading to the decrease of tyrosinase activity, thus affecting the metabolism of melanin. Pathogenic bacteria is a kind of lipophilic yeast, called Malassezia. This kind of fungi is saprophytic bacteria of normal skin, only in some special circumstances, such as high temperature and humidity, local fat and sweat, poor sanitary conditions, etc., the parasitic density of Pityrosporum is increased, and the saprophytic yeast can be transformed into mycelial type.

Third: the bacteria only invade the superficial stratum corneum and do not cause dermal inflammation. The disease is common in tropical and temperate regions with high relative humidity. Young people, especially young men, are more prone to pityriasis variegata due to more activities and sweating. Pityriasis macularis is also common in people who take corticosteroids for a long time. In addition, physical weakness, malnutrition, diabetes and pregnancy can induce the disease.

These two situations can not be ignored, need to go to the hospital dermatology to have a good check, under the guidance of the doctor for treatment, recovery will be faster.
