نکات کلیدی
- Keloid scars are raised skin lesions caused by excessive collagen production while healing from various skin injuries.
- There are multiple treatment options available, such as surgical removal and laser therapy, to help manage keloid scars.
- Emerging treatments and future research offer an optimistic outlook for those affected in the future.
What Are Keloid Scars?
A keloid scar is a type of raised scar, characterized by a rubbery nodule that forms due to excessive collagen production during wound healing, extending beyond the initial site of trauma. Keloids can develop as a result of various skin injuries, شامل:
- Piercings
- Burns
- آکنه
- Insect bites
They are harmless and treatment focuses on providing relief and improving appearance. It is important to note that some individuals are more prone to develop keloids due to genetic predisposition and skin type.
Hypertrophic and keloid scars are two common types of raised scars that can be confused with each other. We’ll now delve into the unique traits of keloid scars, contrasting them with hypertrophic scars.
Characteristics of Keloid Scars
Keloid scars are distinct in their claw-like texture and can bring relief through itching and pain. They often have a shiny, raised appearance and can extend beyond the original scar margin, making them easy to identify. Though keloid scars may seem like a nuisance, they can also be seen as a positive sign of the body’s natural healing process.
Successful treatment options for keloid scars include surgical removal, laser therapy, corticosteroid injections, and silicone gel sheeting.
Difference Between Keloid and Hypertrophic Scars
While both keloid and hypertrophic scars are raised and result from the body’s wound healing process, they have some notable differences. Here are the key differences between a hypertrophic scar and the two types of scars:
- Hypertrophic scars generally stay within the boundaries of the original wound and may even improve over time.
- In contrast, keloids tend to spread beyond the borders of the initial injury and do not usually regress.
- Smooth muscle actin expression is a reliable way to differentiate hypertrophic scars from keloids.
Having grasped the concept of keloid scars and their differences from hypertrophic scars, we can now investigate the reasons behind their formation.
Causes of Keloid Scars
Keloid scars are caused by a combination of skin trauma, genetic predisposition, and increased risk in individuals with darker skin tones. Skin injuries such as insect bites, آکنه, تزریق, body piercings, سوختگی, and hair removal can all lead to the formation of keloid scars.
