Although keloids have been documented in virtually all major ethnic groups, they are most commonly seen in individuals of African, Asian, and, to a lesser degree, Hispanic and Mediterranean descent. Dark-skinned individuals form keloids 15 times more frequently than do their lighter-skinned counterparts.
Of those, the keloids rate for African Americans was 0.8 percent, while the rate for Caucasians was 0.1 percent. After adjusting for age and gender, the study showed that the odds of getting a keloid for African Americans were 7.1 times that of Caucasians.
Keloids are most common in people younger than 30. Black people, Asians, and Hispanics are more prone to developing keloids. Keloids often run in families. Sometimes, a person may not recall what injury caused a keloid to form.
They typically develop on the torso and sometimes on the face and earlobes. Although anyone can get them, keloids are more common among darker-skinned people. Keloids can be painful or itchy but aren't usually dangerous to a person's health.
They develop in people with much skin pigment, so they are found in blacks and Asians. Keloids occur because of an abnormal healing process, and the scar tissue thus formed extends beyond the boundary of the original trauma. They contain excessive quantities of collagen, fibronectin, and chondroitin sulfate.
Keloids can continue to grow for months or even years. They eventually stop growing but they do not disappear without treatment. In some cases, as mentioned above, keloids can return after they have been removed.
Keloid surgery: Your dermatologist can surgically cut out the keloid. While this may seem like a permanent solution, it's important to know that nearly 100% of keloids return after this treatment. To reduce the risk of a keloid returning after surgical removal, most patients have another treatment after surgery.
This benign skin disease can either occur sporadically, or can exhibit a familial pattern. Keloid disease is considered a genetic disease due to a strong genetic susceptibility to keloid formation as it occurs predominantly in people of African and Asian descent, runs in families, and has been found in twins.
Keloid, also known as keloid disorder and keloidal scar, is the formation of a type of scar which, depending on its maturity, is composed mainly of either type III (early) or type I (late) collagen.
Most keloids occur sporadically, but some keloid cases are familial. A hereditary component in keloid etiology has been considered, mainly based on the higher occurrence in darker-skinned races.
Spontaneous keloids are rare, so there are only a few known cases. Findings from studies suggest that these keloids may occur when: The skin injury is so minor that the person doesn't notice it. A disease causes intense inflammation inside the body.
There are no proven methods of removing keloid scars naturally. Some clinical studies have shown that onion extract used orally or on the skin might possibly be effective in improving the appearance of keloid scars and reducing itchiness and discomfort.
Keloids can take 3–12 months to develop after the original injury. They start as raised scars that can be pink, red, purple, or brown and typically become darker over time. The appearance can depend on the location of the keloid, as well as the person's skin tone. Earlobe keloid scars are likely to be round or oval.
Keloids on your ear grow slowly. They may take up to 12 months before they become noticeable, and they may continue to grow for years. They'll eventually stop growing, but they won't go away without treatment.
Protect the injured area from the sun.
After the wound heals, you won't see a keloid right away. Keloids take time to appear. To reduce your risk of developing a keloid, you need to protect the area from the sun. Covering the area with clothing can help.
Conclusion: Keloids never completely disappear to leave skin with normal texture, however they can resolve (flatten and soften) so they no longer burden patients in approximately one third of cases. Scars resolving spontaneously do so early in the disease. Those that don't may resolve after many years of treatment.
In a cohort study in Taiwan, patients with keloids were at an increased risk of developing various forms of cancer -- pancreatic cancer and skin cancer in particular -- when compared to the general population, with an adjusted odds ratio of 1.51 (95% CI 1.39-1.63), according to Kathy Chien-Hui Hong, MD, PhD, of ...
Keloid scars are usually raised, hard, smooth and shiny. They can be skin colour, pink, red, purple, brown, or darker than the skin around them. You can get keloid scars on any part of the body, but they're most common on the chest, shoulders, chin, neck, lower legs and ears.
Keloid growth might be triggered by any sort of skin injury — an insect bite, acne, an injection, body piercing, burns, hair removal, and even minor scratches and bumps. Sometimes keloids form for no obvious reason. Keloids aren't contagious or cancerous.
The growth promoting effects of increased internal stress, primarily, and growth factors released by reperfusing blood, manifest in keloid formation.
Keloids are more common in people younger than 30 years, in pregnant women, and in teenagers going through puberty. People with a family history of keloids are also more likely to get them. Certain areas of the body are more likely to scar than others.
Clinical Appearance of Keloids
They appear generally 3–9 months posttrauma, extend far beyond the area of a pustule or shaving injury, and do not spontaneously regress. They generally continue to grow over years and possibly decades.
Hypertrophic scars are contained within the site of injury and may regress over time, while keloids spread beyond the borders of the initial injury and do not regress. On histological examination, hypertrophic scars tend to have collagen in a wavy, regular pattern, whereas keloids have no distinct pattern of collagen.
Silicone treatments are effective in reducing the size of keloid in about 34% cases when used continuously for six months. Get an steroid injection in the scar, a common treatment for reducing keloid size, if creams or silicone strips are not effective.
