Spider nevi in children between 6 and 10 years of age are most often seen due to elevated estrogen levels and may also be caused by liver disease. If spider nevus appears in children between 6 and 10 years old, the first thing to consider is that it is caused by the increase of estrogen level in the body. When the estrogen concentration in the blood increases, it will lead to arterial capillary dilatation, which causes spider nevus, and both men and women may have this situation. In addition, it cannot be ruled out that it may be caused by liver diseases, such as acute hepatitis and chronic hepatitis, because estrogen metabolism is often carried out in the liver, and when the function of the liver is impaired, it may lead to a large amount of estrogen accumulation in the body, resulting in the formation of spider nevus. Children between 6 and 10 years of age with spider nevus should consult a doctor to find out the cause of the nevus if it is accompanied by other uncomfortable symptoms.
