summary

A friend not long ago found the situation of white spots on his hands, and later went to the hospital for examination, the doctor said he had vitiligo disease, then, what is the reason for white spots on his hands? Let's talk about it.

What reason is white spot on the hand

First of all, trauma is an important cause of hand vitiligo. In daily life, the hand is the main part of labor, so it is more vulnerable to trauma. The phenomenon of vitiligo caused by trauma is not uncommon in clinic, and its specific mechanism is very complex, which is also under further study. When using sharp tools, such as cutting vegetables and apples, patients should pay attention not to hurt their hands.

Secondly, UV exposure is easy to cause hand vitiligo. Excessive ultraviolet radiation will lead to excessive melanin intermediates. These toxic intermediates accumulate in the melanocytes and damage the normal function and structure of the cells. On the other hand, excessive ultraviolet radiation may make the melanocytes over excited and over consumed. Hand exposure, vulnerable to ultraviolet radiation, the risk of vitiligo is also large.

Finally, frequent hand contact with chemicals, especially phenolic compounds are prone to hand vitiligo. Frequent exposure to chemicals is one of the important causes of vitiligo in the hands, among which phenols, such as pyrocatechol, hydroquinone, p-tert-butyl phenol, phenol, butylphenol, butyric acid and so on, have obvious effects. These substances can selectively destroy melanocytes and cause depigmentation. For example, people engaged in rubber, plastic and resin manufacturing industry often contact tert butylphenol, so the risk of vitiligo is greater than ordinary people.

matters needing attention
