It's also possible for a keloid to appear on uninjured skin. This keloid is called a “spontaneous keloid.” Spontaneous keloids are rare, so there are only a few known cases.
Spontaneous keloids, that is, those keloidal lesions that develop without any history of trauma or surgery, are very rare. It is generally believed that they are triggered by microtrauma or minimal cutaneous inflammation in genetically susceptible patients.
Begin as a raised pink, red, or purple scar.
A keloid is usually a raised scar with a flat surface. The color tends to darken with time. It usually ends up being darker than the person's skin, with the border being darker than the center.
Keloids often occur after damage to the skin (eg, surgeries, piercings, burns, acne, and vaccinations). Sometimes, they can occur without any known skin injury.
A keloid usually takes time to appear. After you injure your skin, months can pass before this scar appears. Once it begins, a keloid tends to grow slowly for months or years.
Appears slowly
After you injure skin, it's likely to take 3 to 12 months or longer to see the first signs of a keloid. The first sign is usually thickening skin. About 20% of keloid scars appear more than a year after the injury.
Dermatofibrosarcoma Protuberans is an extremely rare condition that can be confused with keloid, especially if growing to the size of 50 mm or not healing anyway (1, 4, 5, 7). In such cases, a detailed investigation covers core biopsy and CT-imaging to achieve an exact tissue evaluation.
Stress promotes keloid formation by causing dermal distortion and compression which subsequently stimulate proliferation and enhanced protein synthesis in wound healing fibroblastic cells.
Certain areas of the body are more likely to scar than others. Keloids usually occur on the chest, shoulders, earlobes, and cheeks.
Piercing bumps and keloids are different skin conditions that can occur following a piercing. Piercing bumps tend to appear more quickly and do not grow in size, while keloids take time to form and can continue to grow over time. A doctor or dermatologist can advise on the best way to treat keloids.
Ear keloids are a type of scar tissue, so there isn't any pus to squeeze out, like a pimple. Trying to pop a keloid on your ear can damage your skin and introduce bacteria, which can cause an infection.
After the wound heals, apply silicone gel sheets or silicone gel. You can buy both of these products without a prescription. They can help prevent a keloid. To get the best results, you apply a new sheet or gel to the area every day.
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.
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.
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.
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.
Keloids, also called keloid scars, are a type of scar tissue that usually grows at the site of an injury. They can also result from infection, inflammation, surgery, blisters, acne, and body piercings. It is not clear why keloids form, but they are harmless — they do not turn into cancer.
An estimated ten percent of all people experience some degree of keloid scarring. While keloids have the potential to develop in nearly anyone, some groups of people are at an increased risk of developing these skin features. Gender does not play any role in a person's likelihood of developing keloid scars.
Areas of the body that have increased susceptibility to keloid and hypertrophic scar formation include the earlobe, the sternum, the deltoid region of the upper arm, and the upper back. It is thought that these areas are associated with keloid formation due to the higher levels of muscle and skin tension.
Abstract. Background: Keloid is a fibrotic skin disease for which immune cell infiltration is a primary pathological hallmark. Meanwhile, in autoimmune diseases, triggering of the inflammation response can lead to tissue injury and subsequent organ fibrosis.
Shiny, hairless, lumpy, raised skin. Varied size, depending on the size of the original injury and when the keloid stops growing. Varied texture, from soft to firm and rubbery.
A keloid is an overgrowth of scar tissue. They are not cancerous, and they don't affect your physical health. However, they can be harmful to your mental health and extremely sensitive or uncomfortable.
Larger keloids can be flattened by pulsed-dye laser sessions. This method has also been useful in easing itchiness and causing keloids to fade. Pulsed-dye laser therapy is delivered over several sessions with 4 to 8 weeks between sessions. Your doctor might recommend combining laser therapy with cortisone injections.
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.
