Why does the baby have a birthmark

summary

My cousin's son is more than three months old. My cousin's son is very cute, but my cousin is very confused about why there is a big birthmark on her son's neck, which greatly affects his face. When my cousin and I went to the hospital, the doctor told me that there were many reasons for my cousin to have a birthmark. Now I'll tell you why the baby has a birthmark.

Why does the baby have a birthmark

One of the reasons: in the process of embryonic development, especially in the early stage of vascular tissue differentiation, due to the small-scale dislocation of its control gene segment, it leads to abnormal tissue differentiation in specific parts and develops into a baby birthmark. This reason is relatively common, in the process of development, it is easy to cause abnormal embryonic development due to some external factors.

The second reason: according to the observation found that the incidence of baby birthmark girls is higher than boys, generally speaking, girls have a higher incidence of birthmark, some boys have a lower incidence of birthmark, in hemangioma tissue detection found that the level of estradiol increased, estradiol is a kind of estrogen in the human body, which is related to the level of estrogen.

The third reason: the reason for the birthmark of a long baby is due to the lack of nerves dominating the blood vessels at the lesion site, which makes the capillaries dilate and congest. At first, it appears as red or pink patches. Later, it deepens with age, turns into bright red and purple, and thickens into nodules. This kind of reason is relatively rare, if once appears, then represents the baby's blood vessel also to be able to cause the pathological change.

matters needing attention

If a child's birthmark grows in an unimportant place or is not obvious, there is no need to remove it. If I grow on my face or neck, the birthmark can often be exposed, then it needs to be removed by laser or other methods. After removing the birthmark by laser, there will be slight burning sensation and slight redness of the skin at the treatment site, which is a normal reaction. If necessary, local cold compress can be used to relieve or eliminate red heat.
