Keloids can be considered "scars that can not stop." A keloid, sometimes referred to as "keloid scar", is a proliferation of scars, piled up on themselves and hard to the touch, which grow abruptly above the rest of the skin. The keloid usually has a smooth top and pink or purple; It is irregularly shaped and tends to progressively magnified. Unlike scars, keloids do not diminish over time.
After the skin has suffered an injury, the healing process usually leaves a scar flat. Sometimes the scar is hypertrophic, or thickened, but limited to the margin of the wound. Hypertrophic scars tend to be more red and may be impaired by the sun. Treatment with cortisone injections, can accelerate this process. Keloids, on the contrary, may begin some time after the lesion and extend beyond the wound site. This tendency to migrate into surrounding areas that have not been injured, distinguishes originally keloids from hypertrophic scars. Keloids typically appear after surgery or injury, but it can also arise spontaneously or as a result of mild inflammation, like a pimple on his chest. Other minor injuries that can trigger keloids are burns and piercings.>> Index
Keloids are raised, shiny and dome-shaped, varying in color from pink to red. Some keloids become quite large and unsightly. In addition to causing potential cosmetic problems, these scars tend to be itchy, tender and sometimes painful to the touch.>> Index
The doctors have not yet discovered exactly why keloids form in certain people or situations and not in others. Changes of cellular signals that control growth and proliferation may be related to the process of formation of keloids, but these changes have not yet been characterized scientifically.
Keloids are equally common in men and women, although women were the most affected, due to a greater number of holes in the ear lobe and Body Piercing. Keloids are less common in children and the elderly; People with darker skin are more likely to develop them, but the phenomenon can occur in people with all types of skin. In some cases, the tendency to form keloids seems to family nature.
Keloids develop most often on the chest, back, shoulders and earlobes. Rarely develop on the face.
Keloids can develop as a result of minor injuries that occur with piercings. Since doctors do not know the precise reasons why some people are more prone to develop them, it is impossible to predict whether the piercing will lead to their formation. There are some family traditions that seem prone but, for most, it is impossible to predict who will develop a keloid. A person could, for example, develop it into a lobe after having drilled, but not in the other. It makes sense, for those who suffer from a keloid, avoid any elective surgery or piercing, especially in areas of the body prone to scarring.>> Index
The goal is to not ever suffer, so better avoid to undergo surgery or elective procedures, such as piercing and cosmetic / surgical unnecessary health. When it comes to keloids, prevention is crucial because current treatments for the care still leave much to be desired.
The decision on when and whether to remove a keloid depends on the symptoms associated with its development and its anatomical position. A keloid chronically itchy and irritated can be very annoying, but also arranged in aesthetically sensitive areas, causing scarring or embarrassment, are candidates for removal treatment. It is unclear whether early intervention is important, but surely you know that the larger keloids are more difficult to treat.>> Index
The methods currently available for the treatment of keloids are:
to. Cortisone injections: are safe and not very painful. The injections are usually made once a month until you get the maximum benefit; there are great dangers because very little steroid enters the bloodstream and usually help to flatten the keloids. However, steroid injections can make them more red, stimulating the formation of blood vessels near the surface, which later may be processed with a laser. The keloid may look better, but also the best results still leave a mark that will be seen clearly very different from the surrounding skin.
b. Surgery: is risky, because the cut of a keloid can trigger the formation of a keloid similar or even greater. Some surgeons achieve good targets injecting steroids or applying pressure dressings on the wound site after cutting away the keloid. Sometimes radiation is used after surgical excision.
c. Laser: the pulsed laser can be effective to lighten keloids making them look less red. The treatment is safe and not very painful, but it can take several sessions that can be expensive, since such treatments are not generally covered by all insurance plans or the public health.
d. Bandages silicone: this is to bring a bandage made of silicone gel on the affected area for several hours per day, for weeks or months, and is a procedure difficult to sustain for a long time. The results are variable: some doctors claim, for example, to have had success with compression tools in different materials from silicone.
is. Cryotherapy: freezing with liquid nitrogen may flatten keloids but often darkens the treatment area.
f. Interferon: are proteins produced by the immune system of the body that help fight viruses, bacteria, etc. In recent studies, injections of interferon have shown promising results in reducing the size of keloids, although it is not yet certain that the effect is lasting. Current research uses a variation of this method, namely, the topical application of imiquimod, which stimulates the body to produce interferon.
g. Fluorouracil: injections of this chemotherapeutic agent, alone or together with steroids, has also been used for the treatment of keloids.
h. Radiation selective: some doctors have reported a safe and effective use of radiation for the treatment of keloids.
