There is a saying in the industry that the flaws on the face cannot be confused because they are related to destiny. If you point the blessing, you may become bad. From a health point of view, this argument is superstitious, but it makes sense. Some crickets can't be confused. Why? This will be based on the definition and type of embarrassment.
What is what?
The medical "sputum" is a narrow sense, also known as scorpion cell nevus, pigment nevus, melanocyte nevus, or common acquired melanocyte nevus. It is the most common benign skin neoplasm in humans. It is the increase of melanocytes in the epidermis and dermis. Caused skin performance.
What are the classifications?
There are several classification methods for cockroaches, which can be classified from the size of cockroaches, the time of cockroach appearance, or from the level of their skin.
According to the size of the diameter - can be divided into small, medium-sized black cockroach, big cockroach, giant cockroach, satellite cockroach.
· Small cockroaches: Black cockroaches with a maximum diameter of 1.5 cm.
Medium-sized black storks: Black crickets with a diameter of 1.5-19.9 cm are medium-sized black otters.
· Big cockroaches: Black cockroaches larger than 20 cm in diameter are large cockroaches.
Giant cockroaches: Black cockroaches larger than 50 cm in diameter or larger.
· Satellite orbit: It is often accompanied by giant cymbals, and there are several small dragonflies around a larger diameter dome.
Divided by time - can be divided into congenital melanocytes and acquired melanocytes.
· Congenital melanocytes
Congenital melanocytes are composed of melanocytes clustered together and appear usually at birth. However, we may occasionally see that some children are not born with black shanks, but only after several years of birth appear black pimple. The reason may be that at the time of birth, the black pimple was too small to be detected. Or due to the lack of melanin contained in the black lice.
· Acquired melanocytes
As the name implies, that is, after the growth and development, there will be more than one acquired melanocytes in almost everyone. Acquired cockroaches may grow after 6 months of age, until the old age.
Its size is usually 0.1-0.6 cm in size, and it is generally divided into three types. One is the growth in the epidermis. The second is not only distributed in the epidermis, but also partially goes down into the dermis, and the third is located completely. In the dermis. The appearance is usually flat, raised, granular, or other different shapes, and the color is usually brown, black, or blue.
According to the skin level, it can be divided into three types: junction, skin, and mixed.
· Junctions
Brown or black spotted rash, slightly raised, 2-8 mm round, clear boundary, uniform color, smooth surface, hairless, can occur in any part, occurs in the palm of the palm and the external genitalia are mostly borderline ridges.
The nevus cells and nevus cell nests are mainly located at the junction of the skin's epidermis and dermis, hence the border junction. The clinical manifestations are palpebral or slightly higher than the surface of the skin, the boundary state is not clear, and the surface is smooth and hairless.
Generally, any part of the body can be seen, but it usually occurs in the palm, toe or transitional epithelial area. More common in children and youth, rare in adults. The nevus cells at the junction have proliferative and active characteristics and may turn into malignant melanoma.
· Skinner
Intradermal nevus is the most common type of pigment nevus in adults. It is named because its nevus cells are located under the epidermis and in the superficial layers of the dermis. This nevus can occur in any part of the body, but the head and neck are the most common. Occurs in the palm, tendons and genital area.
The appearance of the gills is hemispherical, ranging from a few millimeters to several centimeters, and generally does not increase. Smooth surface, neat edges, and some papilloma-like or basal pedicles. Congenital black spots can appear light brown, dark brown or black.
Its size is generally less than 1cm, the surface is flat or slightly elevated, some smooth, some rough, and some have one or a few hairs. Slow growth, common in the elderly, clinically no reports of malignant transformation of the skin.
· Mixing
Mixed ç—£ has the characteristics of both boundary enthalpy and intradermal ,, so it is named mixed ç—£. It looks like a borderline, and it is a transitional expression of the borderline to the evolution of the skin. It is more common in adolescents. The clinical manifestations are brownish to black papules or rashes with raised skin. The boundaries are clear. There is often hair growth and the pigment gradually fades around.
The mixed nevus hernia cell population is found in the dermis or in the epidermis. It is embedded in collagenous tissue and contains no or very little melanin. There is little or no inflammation in the dermis. The sputum itself has little effect on health and may not be dealt with.
After clarifying the concrete meanings and classifications of 痣, we return to the original question ↓
Which ones are best not to keep?
Although ubiquinone is common, it should not be forgotten. But don't forget that it is a kind of skin tumour. There are benign ones and naturally it will become melanoma. We must keep an eye on their changes. In general, the following types of cockroaches are more likely to undergo malignant transformation.
· Huge spasm: Diaphragm cells with a diameter of more than 6 mm, or sudden increase in the short-term, uplifted warts are more likely to undergo malignant transformation.
· Dysplastic sturgeon: The shape of the sturgeon on both sides is different, the appearance is not uniform, and the edges are irregular. This kind of sting is a stunted sturgeon, and sometimes skin lesions occur, leading to human death.
• Uneven color blemishes: Color unevenness of the same blemishes, or large changes (deepening) of colors in a short time.
· Ruptured, bleeding hemorrhoids: The skin on the surface of the hemorrhoids appears persistent itching, pain, ulceration, and the like. These are all signs of melanoma.
In the above cases, the pathological examination should be performed as soon as possible.
Tip: You can't easily
In order to save money, many people do not go to the hospital but choose remedies. For example, the most common one among the people is the "medicinal water" method. Spread a little syrup to cover the blemishes. This will remove the blemishes by eroding the skin and regenerating the skin. However, it is often not possible to remove the skeleton from its roots, and it will leave a permanent “pit mark†on the face. Seeking the United States will not be an injury to the skin. In addition to this, many ordinary blackbirds that look ordinary are likely to turn from benign to malignant. If you don't know whether it is good or evil, you can easily use a potion to erode it and make it possible to convert benign melanin into malignant melanoma. Melanoma is a malignant tumor with a low cure rate.
Therefore, if the main points are paralyzed, you must go to a regular hospital dermatologist to find a professional doctor. Laser or freezing treatment, let the doctor decide to choose the right one for you.
