It is precisely because there are few people with scar constitution that some books also call people with keloids scar constitution. Keloid shows that after the wound heals, the scar grows outward, the skin surface is hard, and there may be a feeling of red pain, but it will not continue to expand after growing to a certain extent. There is a difference between scar constitution and keloid. After any part of the body is injured, people with scar constitution can have unlimited scar hyperplasia like keloids, while some parts of normal people will also have keloids, or scar healing caused by some reasons. In other words, keloids are an inevitable manifestation of scar constitution, and people with keloids do not necessarily belong to people with scar constitution.
Whether it is a person with scar constitution or a normal person with keloid after wound, the treatment methods are mostly the same.
Generally, patients with hypertrophic scars and keloids can be judged as cicatricial constitution; Generally speaking, it is a scar that protrudes from the skin after trauma and is larger than the wound area. It is not that scar constitution can't do any surgery, but it is generally not suitable for cosmetic surgery and fine surgery, such as excimer laser surgery. Although the microstructure names of skin and cornea are different, the genetic control of scar constitution is the same. For example, even if a little extra tissue grows after laser surgery, it will have a serious impact on vision, so it is still listed as a surgical taboo.
Keloid is the product of excessive proliferation of fibrous connective tissue. If the epidermis of people with scar constitution is damaged, such as trauma, mosquito bites, vaccination, burns, folliculitis, acne, etc. It is very likely to form keloids. Local factors include inflammation after trauma, foreign body stimulation, excessive tension and so on. Keloid is a kind of tumor-like hyperplasia protruding from the skin surface. The surface is smooth, red and shiny, and dilated capillaries are often seen extending outward. The skin is damaged until the edge protrudes outward and the crab's feet are deformed. Skin lesions vary in size, shape and hardness, with many symptoms, itching or tingling. Because of the intense pain, it may be the formation of nerve terminal conduction sensitivity or micro-neuroma, and even the clothes will feel pain when touched lightly. The development is slow, but it continues to increase. Some patients will occasionally become malignant (those who are repeatedly infected with ulcers), and keloids often occur in the chest, shoulders, neck, back and auricle. It can happen to men and women.
