The actual “white spots are not vitiligo, such as white pimples, non-pigmented nevi, aging skin, lichen planus, anemic nevi, and so on.”
How to make a simple self-diagnosis for the white spots on the body? Vitiligo is a common acquired limited or generalized skin pigment loss disease, which modern medicine believes is caused by the loss of melanocyte function of the skin.
For the white spots due to pityriasis alba, children and adolescents are predominant, which are slightly rough to the touch and develop predominantly in summer, especially after swimming, and sometimes after inflammation. Pigmentless nevus mostly develops at birth or soon after birth, and its white spots can expand proportionally with body development, often distributed along the nerve stage, in the extremities mostly into strips or bands, and the trunk can be square, which is a more obvious feature. For skin aging appear white spots, mostly in people over 40 years old, generally more in the exposed parts of the skin, the diameter of the white spots is relatively small, usually green bean size, at most not more than peanut rice shape.
Vitiligo: children, adults onset is very different Since we distinguish between these shapes and sizes of white spots, what are the usual characteristics of the body white spots produced by vitiligo? The incidence of vitiligo is about 0.5-2% without gender difference, from the age of onset, more than half of the patients will have their first onset before 20 years old; from the color of the white spots, vitiligo caused by the white spots from the initial onset is white, and the degree of white is deeper; from the new and recurrence time, around the Qingming Festival is a small peak, which is related to the increase of outdoor activities and ultraviolet light enhancement.
So exactly who are prone to vitiligo? The onset of children is somewhat different from the onset of adults. For children and adolescent patients, the onset of the population has some commonality: relatives have a history of vitiligo; belong to the allergic body; has appeared baldness; have halo nevus. If a child at home has one of these conditions, parents should pay attention. For those who have vitiligo after the age of 20, doctors often ask them to do thyroid function test, this is because many patients are caused by thyroid disease, doing this test can help doctors determine whether vitiligo is related to the thyroid gland, so as to treat the symptoms. In addition, vitiligo caused by rheumatic diseases, work stress, etc. is also more common.
The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. In addition to the doctor’s look and feel this kind of diagnosis, the current use of wood lamp auxiliary examination, the effect is better.
The Wood’s lamp is a 320-400nm long-wave ultraviolet light obtained through a filter containing nickel hydride, which is currently a more advanced clinical diagnostic device in dermatology. This is a new standard instrument to identify vitiligo, can accurately detect how much melanin loss, identify is complete or incomplete vitiligo, can also check out the naked eye invisible lesions have occurred.
