What are black moles and red moles?

What are black moles and red moles? There are also blue moles, which are called Qingji in traditional Chinese medicine and commonly known as Ota nevus, and many of them are present at birth. In Water Margin, Yang Zhi was called Qingmian because he had a blue mark on his face. Veterinarian Lin Gai mistakenly believed that this type of mole was formed when a person was born. When a person has congenital **, the meridians are not in harmony, resulting in poor circulation of qi and blood and obstruction of the skin. The skin is not nourished, so the birthmark is generally larger. What are the causes of red moles? 1. On the surface, there are many reasons for small red moles on the body. The occurrence of red moles is closely related to the permeability of the capillary wall. Generally, some young women will spontaneously and repeatedly develop small red moles, but most of them are distributed on the limbs and there are no obvious skin abnormalities. Over time, they will turn from red to yellow. However, these small red moles will gradually disappear and do not cause any harm to the skin. In addition, the occurrence of red moles is also related to allergic constitution. The small red moles that people see may just be some bleeding spots. They are not raised above the skin and will fade when pressed. This will not harm the body. 2. Generally, red moles are the essence of human qi and blood. They do not cause any harm to the body. They are caused by the circulation of human qi and blood, so they are congenital. However, blood moles similar to red moles are different. This kind of mole is formed after birth and has a great impact on human health. The blood mole can be as big as a wolfberry or as small as a blood bubble. They can appear on the chest, ribs, arms and lower limbs. This is mainly caused by the accumulation of fat, phlegm and dampness, which can easily lead to fatty liver, cirrhosis and cholecystitis. Some patients with fatty liver and chronic hepatitis often have such moles on their skin. 3. If small red moles appear on your body, don't panic too much. You should go to the hospital to check what caused it. At this time, you must first confirm whether it is a spider nevus, and then check the liver function to see if the small red moles are caused by chronic liver disease or cirrhosis. If it is hepatitis B, it will cause the occurrence of spider nevus. Although the small red moles do not need to be treated at this time, the liver disease must be thoroughly treated. When the liver disease recovers, the small red moles will no longer exist. 4. Red mole <br />Red mole is neither painful nor itchy. It is medically known as senile hemangioma, also known as cherry hemangioma. This disease is more common in the elderly, but it also occurs in some middle-aged people. This disease is harmless to the body. Senile hemangiomas mostly occur on the trunk and limbs, but not on the hands and feet. They are about 1-5 mm in diameter, slightly protruding from the skin, occasionally up to the size of a soybean, soft in texture, and non-tender. Generally speaking, this disease does not harm human health, but only affects the appearance. Generally no treatment is required, but some people want to treat this disease for aesthetic reasons. Laser, cryotherapy or electrotherapy can be used, and the results are usually satisfactory. Common red moles are usually bright red or cherry-colored, about the size of a sesame seed, usually occur on the trunk and proximal limbs, and increase in number with age. This is because the skin surface has atrophied and blood vessels have proliferated in the dermal papilla, so red moles grow, which is generally harmless to the body. However, not all red moles are like this. There is also a kind of blood mole, which is often considered to be an ordinary red mole because it is also bright red in color. Blood moles are generally the size of mung beans, red or brown in color, and raised on the surface of the skin. They are also called spider moles. Blood moles usually occur due to increased estrogen and excess fat in the body. If men and elderly women suddenly develop blood moles, it may indicate liver disease, such as liver cancer, chronic hepatitis or liver failure. This is because after the liver becomes diseased, it cannot normally inactivate estrogen, causing the estrogen content to rise and blood moles to appear. For some patients, the appearance of blood moles indicates that their liver function is already tending to failure. Red moles are generally distributed on the trunk, such as the chest and back. Some patients also have them on the face or front of the arms. Red moles (also called blood moles) change with the blood content in the body. If the patient suffers from anemia, severe bleeding, shock or death, the blood mole will disappear. Blood moles are not just a symbol of liver disease. Blood moles can also be seen in patients with rheumatism, rheumatoid arthritis, vitamin deficiency, lupus erythematosus and other diseases. Some pregnant women may also develop blood moles due to increased estrogen concentrations in their bodies, which usually disappear within a few months after delivery. The reasons for small red moles on the body are: 1. Related to the permeability of capillary walls: A small number of healthy women of childbearing age will spontaneously and repeatedly develop small red moles, mostly on the limbs. After a few days, they may turn into bluish-yellow pigmentation and finally disappear gradually without leaving any traces. This is medically called simple purpura, which generally has no effect on health. 2. Related to liver function: It is a pathological phenomenon called spider nevus, which is generally common in patients with acute or chronic hepatitis or cirrhosis. 3. Related to allergic constitution: there may be some bleeding spots that are not higher than the skin and do not fade when pressed. Patients may develop symmetrically distributed small, dense bleeding spots in batches over a few days or weeks, mainly on the lower limbs, which is medically known as allergic purpura. 4. Roseola: It may be a bright red circular macules, which is formed by the dilation of blood vessels around the lesions. The rash can be eliminated by tightening the nearby skin or pressing with fingers, and will reappear when released. It often appears on the chest and abdomen. It is a characteristic rash that has diagnostic significance for typhoid or paratyphoid. Black mole <br />Hospital doctors pointed out that moles are localized skin pigmentation abnormalities that can be present at birth or acquired later in life. A healthy person usually has 15 to 20 moles on their skin. Most of these moles are benign and do not require treatment. But some moles grow on the face and affect the appearance, and different methods can be used to remove them. What is the reason for black moles on the body? Commonly used methods for mole removal include: laser method, freezing method, electrocautery method, spot removal machine method and chemical agent method. Generally speaking, it is safe to use laser now. A mole is a benign tumor that everyone has on their body. We also call it a freckle. It is composed of a cluster of pigmented mole cells. Don’t underestimate these black spots on the body. They are common on the face and affect our appearance. More importantly, they can turn into malignant melanoma (often called malignant melanoma), a malignant tumor with extremely high malignancy and mortality rate. There are many ways to classify moles. According to the time of appearance, they can be divided into congenital moles and acquired moles; according to size, they can be divided into giant moles (larger than 2 cm in diameter) and small moles (smaller than 2 cm in diameter); medically, they are divided into intradermal moles (raised on the skin surface), junctional moles (flat surface) and mixed moles (between the two). The moles most likely to become malignant are giant congenital nevi and junctional nevi. It is not fully understood why a small black spot can turn into a deadly malignant mole. If the mole grows on the palms, feet, neck, chest, back, armpits and other parts of the body that are prone to wear and tear, repeated stimulation from external factors will increase the chance of malignant transformation. Some sisters think that the moles on their faces affect their appearance, so they go to a beauty salon to have them removed. However, this actually involves certain risks. Some moles grow deep under the skin, and laser removal will not only fail to achieve the desired effect, but will stimulate it and increase the risk of cancer. How are moles formed? Melanin, also known as nevus, mole or black mole, is the most common benign skin tumor composed of normal pigmented nevus cells and is occasionally seen on the surface of the mucous membrane. There are various types of clinical manifestations. The colors are mostly dark brown or ink-black, and there are also colorless moles without any color. Such as intradermal nevus, junctional nevus, mixed nevus, giant nevus, blue nevus, juvenile melanoma, etc. Some types may become malignant under certain conditions, which deserves attention. Pigmented nevi often occur on the face, neck, back and other parts of the body and can be seen on any normal human body. It may be present at birth or develop gradually in the early years of life. Most grow slowly or remain unchanged for many years, but spontaneous degeneration rarely occurs. What causes moles? 1. Intradermal nevus is derived from the differentiation of large nevus cells, which tend to be more mature small nevus cells and enter the dermis and its surrounding connective tissue. 2. Junctional nevus cells exist at the junction of the epidermis and dermis, in the form of multiple nests with clear boundaries and uniform distribution distances; the upper half of each nest is in the bottom layer of the epidermis, and the lower half is in the superficial layer of the dermis. These nevus cells are large and darkly pigmented. 3. In the process of nevus cells entering the dermis, compound nevus often produces intradermal nevus and residual junctional nevus at the same time, which is a mixed form of the above-mentioned vehicle-type nevus.
