Causes of fetal mark on the face of newborn

summary

There are many newborn babies with birthmarks on their faces as soon as they are born. They look very uncomfortable, so you Baoma want to know the reason why they have birthmarks on their faces. Now I'll tell you about it.

Causes of fetal mark on the face of newborn

First, if the long birthmark on the face of the newborn is Mongolian plaque, it can disappear naturally. Mongolian plaque is the most common birthmark of the newborn, which is congenital, especially in yellow people.. Mongolian plaque is caused by the delayed disappearance of some melanocytes in the dermis during embryonic development. Although the probability of its occurrence is quite high, almost this kind of birthmark will disappear naturally as the baby grows up.

Second, if the birthmark is a coffee milk spot, it will never disappear. As the name suggests, it is because the color of the birthmark is light brown, a bit like the color of coffee and milk. The diameter is generally 0.5-5cm, oval, and the boundary between spots is clear. Except that the palms and soles of the feet are not invaded, this kind of birthmark can appear in any part of the body, most of which occur in infants before the age of five, with a probability of about 1%.

Third, nevus of Ota. Nevus of Ota is also a disease with increased melanin in the dermis. It is characterized by blue, brown, black or mixed color patches. The rash is distributed on one side of the face and occasionally occurs on both sides. It can affect the conjunctiva and sclera of the eyes. The lesions of some patients tend to increase slowly. Nevus of Ota has no genetic tendency and generally does not become malignant, but once it occurs, it will not retreat for a lifetime, seriously affecting the appearance. Q-switched laser can be used to treat the birthmark after the nevus of Ota rash is stable. This method destroys the melanocytes through selective photothermal effect. The treatment result is ideal, the success rate is high, and the side effects are relatively small.
