Some of them are present since birth, some disappear slowly, and some persist into adolescence and adulthood, which may cause discomfort and affect beauty and social interaction. The following is a brief description of a mole of Ota. The character “Yang Zhi, the Green-faced Beast” in “Water Margin” was isolated, ridiculed and nicknamed by children since he was a child. …… What is a mole of Ota? It is not a mole, but a large brown, greenish-gray or blue-purple spot on the eyebrows, eyes or cheeks, mostly unilateral, like Yang Zhi, and only a few people have both sides. Nearly half of the nevus of Ota are already there at birth, and the other half appear after the age of 10. Since nevus of Ota grows on the face, with large area and dark color, it has a great impact on the beauty of a person’s face, and indeed causes troubles and worries to their work and life. The effect of laser treatment is very good, and you can usually see considerable improvement after several treatments. Coffee spots are not painful or itchy, they are flush with the skin surface and can grow anywhere; most of the coffee spots are not present at birth, but more often when the child is a few months or a year or two old, parents may suddenly find out, “Hey, when did the child grow a light brown spot, and I didn’t see him hurt or scratch? The reason why it is so hard to notice is that the spot itself does not cause any abnormal sensation, it is just a spot. As we grow older, the spot may get bigger, but most of them are less than 1.5 cm in diameter. This makes many people think that having coffee spots means having a tumor, but in fact, people who have coffee spots do not necessarily have neurofibromas, but people who have neurofibromas usually have coffee spots. Most children with café au lait spots have normal health conditions, and they may just have a spot for life, and this spot can be removed with laser. However, for children with coffee spots larger than 1.5 cm in diameter and more than 6 spots, or children with multiple nodules or lumps in addition to multiple coffee spots, it is necessary to go to the hospital to improve the relevant tests to see if there is a combination of neurofibromas and whether they need to be removed surgically. Strawberry spot This is not something that grows only after eating strawberries, but is a kind of hemangioma that protrudes from the surface of the skin, which is medically called “capillary hemangioma”. It usually appears within a few weeks of birth, starts to increase in size in a few months, and grows to its maximum size around the age of 1. Most children can completely or partially disappear on their own by the age of 5-7. Therefore, just remind your child not to touch the strawberry spots too often, as this may lead to bleeding or even infection. If this is not possible, treatment can also be considered. Erythema nodosum likes to grow on forehead or back of neck, it is said to be benign tumor, in fact, it is just a pile of capillary expansion, some people have Erythema nodosum growing on eyelid, your piece is small and not protruding, Erythema nodosum will not become malignant, depending on the situation most of them can fade away, those that cannot fade away affect the beauty or can be treated by laser. Mongolian spot First of all, Mongolian spot is not a characteristic spot of Mongolian people, Mongolian spot is not good-looking, but not many parents are worried about it. Because it does not affect the growth and development, and it is not on the face, but on a part that does not need to be seen, so just ignore it! Relax, after a year or two, when you give your child a bath, look at it, eh, how smaller and lighter? In a year or two, hey, the Mongolian spot is gone! Yes, the most important feature of Mongolian spots is that they will fade away naturally within a few years, so there is no need to treat them at all.
