Ms. Qian recently encountered an embarrassing and worrying thing. She has a natural mole on her left cheek, which has been with her for more than 30 years. Because it is not in the front of her face, she usually doesn’t care. The mole suddenly burst a few days ago. Ms. Qian searched the Internet and found many posts saying that this may be a sign of some kind of disease. Terrified, Ms. Qian hurried to the hospital for a pathological test and found no lesions, but the doctor told her that the sudden rupture of this mole may indeed be a sign of some lesions.

Ms. Qian was very afraid, so she came to us to remove the mole with surgical cosmetic methods. At the same time, she also asked to remove a birthmark on her stomach that was a little bigger than the mole. We have methods to remove some birthmarks, but not all birthmarks have methods to remove, and there is no need to remove some birthmarks. Through Ms. Qian’s experience, let me briefly introduce the birthmark. Knowledge about birthmarks may not be easy to see at ordinary times. Compared with some large birthmarks, there is really no need to worry too much, because some birthmarks are really eye popping.

birthmark is an abnormal hyperplasia of skin tissue during development, with abnormal shape and color on the skin surface. Birthmarks can be found at birth, or they may emerge only a few months after birth. Birthmarks can generally be divided into pigment type and vascular type. Common pigment types include OTA mother spot, congenital melanin mother spot, coffee milk spot, etc., while vascular types include wine stain, strawberry like hemangioma, etc. The incidence of

birthmarks the incidence of

birthmarks of newborns is about 10%, which can be said to be very common. Most birthmarks only affect the appearance and do not need special treatment. However, some birthmarks will be combined with abnormalities of body organs and even malignant changes, which must be actively treated. For example, some cavernous hemangiomas proliferate too fast, which will cause limb deformity, not only the appearance is not good-looking, but also the energy barrier. Even when the expansion speed of hemangioma is too fast, it will form tissue necrosis and excessive consumption of platelets, resulting in low coagulation function and continuous bleeding. Some hairy dermoid nevus may become malignant melanoma in the future and cause death after cancer cell metastasis.

salmon erythema

about 1 / 3 of newborns will have this birthmark. It is a small, reddish patch, usually laid flat on the skin. Most of them appear on the back neck, between the eyes, on the forehead and eyelids. With the continuous growth of children, most of them will gradually disappear.

port wine stain

port wine stain is also called port wine stain. It tends to occur on the head, face and neck. It is dark red and irregular spots, not higher than the skin, and easy to fade under finger pressure. It can increase with the growth of the human body. Most of it exists for life. It can be treated with drug light therapy, which generally will not cause harm to the human body.

Mongolian plaques

Mongolian plaques are the most common birthmarks of newborns. They are congenital, especially in yellow people. It often appears on the baby’s waist, hips and back. It is manifested as light gray cyan or dark cyan spots. Most of them occur in a single piece, which is round or oval, and the realm is unclear. Mongolian macula is caused by the delayed disappearance of some melanocytes in the dermis during embryonic development.

coffee milk spots

except that the palms and soles of the feet are not infringed, this birthmark can appear in any part of the body, mostly in infants before the age of five, with a probability of about 1%. If there are only a few coffee milk spots, there is generally no adverse effect, but if there are more than six spots and the diameter of each spot is greater than 1.5cm, the probability of neurofibromatosis is significantly increased. Neurofibromatosis is a genetic disease that invades the skin and nervous system at the same time, and may affect the baby’s intellectual development.

strawberry hemangioma

capillary hemangioma, also known as strawberry hemangioma, occurs at birth or in the neonatal period. It often occurs in the head, face and neck. It grows rapidly 2 ~ 6 months after birth and forms a strawberry soft mass higher than the skin. Although it will not disappear, it has no impact on health.

cavernous hemangioma

it is like light blue sponge tissue filled with blood. It usually appears under the skin of the head or neck. If it grows deeper, the skin covered on it looks no different and disappears before puberty.

venous malformation the venous dilatation caused by

venous malformation may not have obvious characteristics at birth, and it will become more and more obvious with age. Venous malformations occur in 1% to 4% of infants. It often occurs on the chin, cheeks, tongue and lips and can be treated with hardener or surgery.

congenital pigmented nevus

congenital pigmented nevus and hairy nevus are black nevus existing at the birth of the baby. They vary in size and can invade the whole back, neck or whole limbs. The small diameter is usually in the range of 0.6 ~ 2cm, mostly dark and black coarse hair. This kind of nevus will increase with the growth of the baby, and has a certain tendency of malignant transformation.
