Newborn babies should beware of 5 kinds of moles, because there are some pigmented spots on the skin of newborns, which we call birthmarks. There are more than 40 kinds of diseases caused by birthmarks, but there are only 4-5 common ones, such as neurofibromatosis, tuberous sclerosis and pigmentary disorders. And the location of the birthmark is a prediction that the baby will be accompanied by neurological symptoms, which may develop only when he/she grows up. Congenital moles Moles are the most common among birthmarks. Moles can be large or small, smooth or hairy. About 1% of newborn babies will have this type of mole. Characteristics: Irregularly shaped, small ones are only about 2 mm in diameter, while large ones can invade the entire back, neck or entire limbs. No matter what kind of mole, especially if it begins to grow or change color, it should be promptly examined by a dermatologist. Although most moles are benign, there are a few such moles that can later become malignant and may even develop into skin cancer. If the area is large, they should be treated and should be taken seriously. Strawberry spot Usually this birthmark appears on the face, scalp, back or chest and is mostly red or purple in color. It usually starts as a pale area and then quickly turns into a deep red raised patch, much like the shiny surface of a strawberry. It is the result of capillaries that are not connected to other blood vessels in the body and rarely occurs at birth, usually forming and appearing 4-6 weeks after birth. Most strawberry spots fade on their own by the age of eight or nine and rarely require treatment. Strawberry spots should also be examined by a dermatologist if they rapidly increase in size and rise significantly above the skin’s surface, regardless of where they are growing. Dark red spots When babies are first born, they usually have discolored spots on their temples and face. At first, the baby’s skin remains smooth, and the color spots vary in shape and size with well-defined boundaries. This color spot is usually also called simple hemangioma. This kind of red spot is first peachy red, and as the baby grows older, it becomes darker and darker to lavender. Also, dark red spots are triggered by dilated capillaries and most of them become larger and larger. If they grow on the eyelids they increase the risk of glaucoma and need to be treated. ”Mongolian spots” are usually dark blue or light grayish-blue, often grow on the baby’s buttocks, but may also be scattered around the waist, back, etc., and are round, oval or square, and the boundaries are not very obvious. These spots are nothing more than pigmentation on the surface of the skin and will almost always fade away naturally before the baby starts school. Spongiform hemangioma Spongiform hemangioma is a red and purple mole caused by the swelling of blood vessels deep in the skin. It resembles a light blue sponge tissue filled with blood. They usually appear under the skin on the head or neck, and if they grow deeper, the skin overlying them looks no different. Some of them may disappear on their own before puberty, or they may remain permanently.
