Overview of keloids
Keloids, otherwise called keloid disorder and keloid scar, is the arrangement of a kind of scar which, contingent upon its development, is composed mainly of type III (early) or type I (late) collagen. It is the result of excessive growth of granulation tissue (collagen type 3) at the site of a healing skin injury that is slowly being replaced by type 1 collagen to a person’s skin colour or from red to dark brown.
A keloid scar is benign and not contagious, but sometimes it is accompanied by intense itching, pain, and changes in texture. In severe cases, it can affect the movement of the skin. Keloid scars are observed 15 times more often in people of sub-Saharan African descent than in people of European descent. It should not be confused with hypertrophic scars, which are raised scars that do not extend beyond the boundaries of the original wound.
Keloid comes from an overgrowth of scar tissue. In general Keloid scars will be bigger than the original wound itself. It may take weeks or months to fully develop.
- A flesh-coloured, pink, or red localized area
- A lumpy area of skin that is usually raised
- It is an area that continues to grow larger with a scar over time
- An itchy patch of skin
While keloid scars may itch, they are usually not harmful to your health. You may feel potential discomfort, tenderness, or irritation from your clothing or other forms of friction. Keloid scarring can form in large areas of the body, but this is generally rare. When this happens, the hardened, tight scar tissue may restrict movement.
These are often a cosmetic concern rather than a health problem. You might feel shy if the keloid is very large or in a very visible location, such as your earlobes or face.
What causes keloids?
Most people develop these scars after injuring their skin, such as a cut or puncture. Getting a tattoo or penetrating can likewise cause a keloid. Sometimes the surgical scar turns into a keloid. Some women who have had a cesarean section (cesarean section) or a hysterectomy develop keloids after surgery.
Some people develop keloids when serious acne clears or the chickenpox fades. It is also possible to get keloids after getting an insect bite or pollen. Wearing tightly braided hair causes keloids in a less number of people. Some men who shave their faces develop keloids in the beard area.
Keloids can also form on unaffected skin. These keloids are called “spontaneous keloids”. It usually appears on the chest and develops in people with a family history of keloids. When keloids develop spontaneously, many keloids are likely to appear.
It remains unclear why some people have scars in this way. To find why a few people create keloids, dermatologists keep on examining these scars. Finding the cause can lead to better treatment and more effective ways to prevent keloids.
Diagnosis of keloids
A specialist analyzes keloids dependent on their appearance and a past filled with tissue injury, for example, medical procedure, skin breaks out, or body penetrating. In rare cases, the doctor may remove a small piece of skin for examination under a microscope. This is called a biopsy.
The goal of treatment is to flatten the keloid, smooth it, or shrink it. It can be difficult to get rid of. Sometimes they come back after treatment. Many doctors will use a combination of treatments to achieve the best results. Treatments include the following:
- Corticosteroid injection. Medication in these shots helps shrink the scar.
- Scar freezing. Treatment is called cryotherapy, and it can be used to reduce the hardness and size. It works best on smaller walls.
- Wearing silicone strips or gel over the scar. This can help flatten the keloid.
- Laser treatment. This can help flatten the keloid. The colour may also be faded.
- Surgical removal. This involves cutting out the keloids. Most of these will return after this treatment.
- Decompression therapy. After keloid surgery, pressure on the area reduces blood flow. This can help prevent the keloids from returning.
- Different treatments work for different people. Converse with your PCP about the treatment choice that is appropriate for you.
Medicines for keloid scarring can be troublesome and not generally powerful. For this reason, it is important to try to prevent skin injuries that may lead to keloid scars. Utilizing pressure pads or silicone gel pads after an injury may also help prevent keloids.
Sun exposure or tanning may discolour the scar tissue, making it slightly darker than the skin around you. This can make the keloids stand out more. Leave the scar covered when you are in the sun to prevent discolouration.
Although it rarely causes harmful side effects, you may not like their appearance. You can treat this disease at any time, even years after they have appeared. So if the scar is bothering you, check it out.
