Birthmarks, many people have them. There are even various theories circulating among the people. One of them is that birthmarks on different parts represent different fates and so on. However, some birthmarks may be a sign of disease.
Be sure to pay attention if you find coffee-colored patchy birthmarks in multiple places on your body, as this may be a sign of neurofibromatosis. Neurofibromatosis is an autosomal dominant neurocutaneous syndrome that begins in childhood in many people and is characterized by café-au-lait spots and neurofibromas. It often involves multiple systems, including concurrent skin, bone, Damage and dysfunction of organs and other tumors.
Coffee spots are latte-like in color and slightly darker than normal skin. Most coffee spots are uniform in color, round or oval in shape, irregular in shape or have a few jagged edges, which are easy to spot and vary in size. They range from freckles the size of a rice grain to tens of centimeters, and can be located anywhere on the body. Usually present after birth, they are often considered to be birthmarks and ignored. Café-au-lait spots will not disappear on their own as you age.
Doctors remind: If you have multiple "coffee stain" birthmarks on your body, more than 6, and the diameter is greater than 5 mm before puberty and greater than 15 mm after puberty, you should be alert to whether it is neurofibromatosis type I. If the above café-au-lait spots appear, it is necessary to check whether there are tumors in various systems of the body, whether there are abnormalities in growth and development, etc.
After some children are born, parents will find red spots on their bodies, which look like birthmarks, are thick and spongy to the touch.
The origin of this type of erythema is actually infantile hemangiomas, commonly known as "red birthmarks." Cavernous hemangiomas are caused by swelling of blood vessels deep in the skin. They may disappear on their own or they may remain permanently. If they are unsightly or if they grow in dangerous places, such as near the trachea, they may need to be surgically removed.
The timing of hemangioma treatment is also important. Although it is said that the earlier the treatment, the better the effect, but for many parents, this time is difficult to grasp, so it is best to seek medical treatment as soon as you discover that your child has hemangioma. Although most hemangiomas do not cause serious complications, the enlargement and thickening of the hemangioma during the growth period may make it difficult to resolve, take a long time to resolve, and leave defects such as incomplete regression and local depression.
What appears to be a black or dark brown birthmark is actually a pigmented nevus. Moles vary in size, and those with larger areas are called giant nevus. Pigmented nevi are accompanied by hair and may become malignant tumors. Before the malignant transformation of a pigmented nevus, there are the following signs: the area increases and the color deepens; hair loss, scab removal, surface ulceration, bleeding, and the formation of ulcers; satellite lesions the size of needle tips appear around the nevus; local inflammation, itching or pain.
