There are white patches on the skin that look like chalk dust, which is commonly known as leukoplakia, also known as vitiligo. A junior high school student had panda-like white circles under his eye sockets since elementary school. The area of the circles gradually expanded and he was diagnosed with vitiligo. Treatment is still ongoing. The area has stopped expanding and the color is gradually approaching normal. Zeng Xinglong said that vitiligo is a disease of abnormal melanin, and patients need to pay special attention to sun protection when going out. Zeng Xinglong, deputy director of the dermatology department at Shutian Clinic, said that vitiligo is a phenomenon in which abnormal skin color is caused by abnormal melanocytes. The cause of the disease is still unclear. Some clinical studies have shown that it may be related to autoimmune diseases, genetics, psychological stress, abnormal thyroid function, hematopoietic insufficiency, melanin deficiency, etc., of which about 20% are caused by genetics. Vitiligo often occurs on the head, face, limbs, eyes, nose, mouth, armpits and lower back, but it may also occur on the lips and genital mucosa. The size and number vary from person to person. In severe cases, it may even spread throughout the body. The range may gradually expand, or it may remain static. The prevalence of vitiligo is about 1-2%, and it most often occurs in young people between the ages of 10 and 30. 50% of patients develop the disease before the age of 20. Treatment methods include topical medication, light therapy, and surgical treatment to allow melanin to regrow in the white spots and improve skin color. Zeng Xinglong reminds that in terms of diet, you can eat more foods containing vitamin B group, such as black beans, milk, carrots, spinach, etc. When going out, you should pay special attention to sun protection, because the white spots lack the protection of melanin and are more likely to get sunburned due to excessive exposure to the sun, and even increase the risk of skin cancer. |
