I don’t know if you have noticed it. This interesting phenomenon -
Some newborn babies will have some blue, bruised birthmarks on their bodies. Most of these birthmarks will appear on their butts, just like they are being beaten.
There are even various sayings among the people:
Some say it was caused by the squeeze when the baby came out of the birth canal;
Some say it was a midwife who slapped the baby's butt vigorously in order to make the baby cry; some even say it was a natural mark...
Inexperienced mothers may think that the baby had skin disease as soon as they were born.
is not only the "blue green" on the baby's butt, do you think adults don't have it?
Many adults obviously didn't hit it, but found that there were a few more bruises on their bodies for no reason? Today we will talk about what "wuqing" is. What exactly is the "blue green" on
?
The "black green" on the buttocks of a newborn baby is not bruised, and this "black green" is called "Mongolian spots".
Since "green butts" are more common among Mongolians with yellow skin, they are called "Mongolian spots". They are a common and normal skin phenomenon for newborns.
Generally speaking, the color of Mongolian spots will gradually become lighter or even disappear from black green, and there will be no color change.
The bruises that appear inexplicably on adults are completely different from Mongolian spots in terms of triggers and manifestations.
This bruise is caused by subcutaneous bleeding. It is usually caused by rupture of the capillary after the skin tissue is hit by external forces, trauma, etc.
Therefore, the color will also change, and there will be a change in color system.
first turns red, red turns dark purple, and then changes from blue-green to golden yellow, and finally turns to normal skin color.
Sometimes, even though they didn’t hit, they still appear black and green. In addition to eliminating unawareness in sleep, you need to be alert to whether there is spontaneous subcutaneous bleeding caused by coagulation problems, and seek medical attention in time once discovered.
How do Mongolian spots form?
Mongolian spots are usually "special" birthmarks that babies have when they are born.
It can appear in any part of the baby's body, but it mostly appears in the buttocks, waists and backs. There are also a few that will grow on both lower limbs, trunks, shoulders and other parts.
Mongolian spots range from a few millimeters to more than ten centimeters, ranging in size.
is mostly blue-colored, does not protrude from the skin, and the touch is as smooth as normal skin.
Mongolian spots are formed due to the accumulation of melanocytes and precipitation in the dermis.
When the human body is still in an embryonic state, melanocytes move from the neural spine to the epidermis, fail to penetrate the junction of the epidermis and the dermis, trapped deep in the dermis to form Mongolian spots.
Mongolian spots are a unique genetic disorder on the skin, which is not harmful to the human body. The probability of occurrence is not gender-oriented, and the rate of occurrence is equivalent to that of men and women.
What is the difference between Mongolian spots and birthmarks?
Simply put, Mongolian spots are a type of birthmark.
Birthmark generally indicates pigmented skin abnormalities that occur shortly after birth or birth.
usually grows slowly and has no obvious discomfort such as itching. It is mostly caused by vascular malformations or abnormal pigment formation.
Its incidence rate is about 10%, which can be said to be relatively common.
can be divided into two categories: pigment type and vascular type according to the content and anatomical differences of various pigments in the skin. Mongolian spots are one of pigmented birthmarks.
Will Mongolian spots change badly?
Mongolian spots will gradually fade as the baby grows older.
Most Mongolian spots can disappear at around one year old, while some children will last until three or four years old, and it is very rare that they do not disappear.
In addition, Mongolian spots do not cause malignancy, so treatment is not required.
However, a very small number of children's Mongolian spots grow on obvious parts such as face, hands and feet, which can easily cause trouble to children, causing them to feel inferior and affect their psychological development.
If the above situation occurs, pulse laser , surgical, frozen, carbon dioxide laser and other methods can be used for treatment and intervention.
Therefore,
"blue green" on the buttocks of a newborn baby
is not pinched out by someone
most of them are naturally formed
and will slowly withdraw
Don't worry too much!
