Keloid scars

What are keloid scars? Why do so many people fear them? Well, these types of scar can include too much collagen of the stage three variety. Instead of being replaced by healthy skin, the area that was injured or damaged is replaced instead with granulated tissues or grains, also known as collagen. The scars appear to be firm and pink to brown fibrous type nodules or rubberized lesions. Though they appear to be like lumps, they are benign, not cancerous and cannot be contracted by someone else. They usually give a person some pain and itchiness. Even the texture of them may change over time and affect how the skin moves. Most importantly, unlike hypertrophic scars, these scars can grow beyond the original boundaries of the injury or wound.

Usually these scars extend like growing claws that reach across the skin. The pain from them can be like being poked with a needle. They may suddenly become itchy, so much so that nothing can stop it. However, sensations vary from person to person. Some may eventually get infected or may form into ulcers. As a result there are numerous options for treatments, including surgery and laser treatment.

By rights keloid scars are in fact a type of tumor. Though they are not cancerous, their make-up is not that much different. They can consist of proteoglycans, elastin, fibronectin and collagen, with everything bundled together into nodules deep within the dermal layer of the original lesion, incisions or wound. They appear to have defined centers and can causes disfigurement if left untreated. Worse though, they can stop a joint from moving at all.

Keloid scars are experienced by both of the sexes and not just in adults. Quite often the people that are most at risk include people of African nationalities, though proof has shown that young females that had their ears pierced have a much higher rate than that found in males. So, what are the best treatments recommended by doctors? Well these include:

  • Intra-lesional corticosteroids

  • Excision

  • Silicon gel sheets

  • Cryosurgery

  • Radiation therapy

  • Interferon alpha injections

  • Pulsating dye lasers

Keloid scars

Keloid scars are abnormal because they grow well beyond the normal boundaries of the original scar where a skin type injury took place. Usually, they begin where the skin was originally damaged and continue to grow until they are raised above the normal level of the skin, even extending beyond it. Most people can get keloid scars under the right circumstances, but usually olive and darker skinned people have a higher risk for reasons yet unknown. Light skinned people can still get these scars, but are less prone to do so. In fact, most of these scars occur on the back of the neck, earlobes, upper back and deltoid section of the upper part of the arms. What causes them still has yet to be determined.

Factors Contributing to Keloid Scar Formation

The most common contributing factors that lead to keloid scar formation are amongst the most obvious. It is seems that the tension of the skin and muscles can make it easier for these scars to form on the back and upper arms. Skin traumas are a great contributor, as are repeated type traumas on the same spot, the introduction of foreign type bodies within a wound and wound infections. Some experts have suggested that the scarring of keloids might be genetically connected through families. Some theories suggest that excessive MSH hormone amounts, the reduction in collagen maturity, the increase in collagen solubility, blocked small types of blood vessels, oxygen deprivation to the wound and deficiencies might have some part to play, but realistically no studies have yet shown conclusive correlations.

Are Keloid Scars Preventable?

Are keloid scars preventable? Is any scar preventable? The obvious answer to this has to be no because unless a person can avoid injuries of even the most minor type and surgery, the chances of preventing scarring at all is very unrealistic. It seems that little can be done to prevent them because little is known about how they form and why some people get them and others do not. However, most experts suggest that how a wound is cared for can make some difference. That is why a person with a healing wound has to ensure that their wound stays clean, though this should be done regardless. If a person is aware of a history of keloid scarring within their family then a person can take extra precautions, avoiding taking risks, driving carefully and not getting tattoos and piercings. A person could even have a chat with a doctor before agreeing to any surgery, but there are simply some things that a person cannot avoid.
