When a wound of a certain depth or more occurs on the skin, it is difficult to avoid scar formation, although the degree may vary. Most scars remain as hypertrophic scars, which are slightly raised above their original size after the wound heals. However, scars that are constitutionally much larger or grow wider than the original wound are called keloids. Keloid scars are significantly influenced by constitutional factors and are known to be challenging to treat due to variations in their shape, color, thickness, and location of occurrence. Today, we will learn more about the characteristics of keloid scars.
How do keloids differ from simple scars?
Unlike typical scars, keloids are characterized by growing beyond the size of the wound and invading the surrounding healthy skin. Although they are not malignant tumors like cancer, keloids often become red, itchy, or painful when they grow or enlarge, which is a primary reason for seeking medical attention.
Why are keloids difficult to treat?
Keloid scars are not merely a reaction to skin damage; constitutional factors play a significant role. Due to these constitutional factors, along with the keloid's shape, color, thickness, and individual characteristics based on the site of occurrence, the treatment approach can be complex and challenging.
Where do keloids commonly occur?
Keloids tend to form in areas where the skin is stretched or moves frequently. Representative areas include:
- Chest area
- Shoulders
- Back
- Chin area: Keloids can often form here due to frequent movement when speaking or eating.
- Earlobes or ear cartilage: Keloids often develop after procedures such as ear piercing.
How can I tell if I have a keloid constitution?
There is no clear way to visually distinguish whether someone has a keloid constitution from birth. However, you can suspect a keloid constitution in the following cases:
If, after a wound heals, the affected area swells much larger than the original wound, becomes red, and continues to increase in size, it is highly likely to be a keloid. Furthermore, if you have a history of keloid scars, it is important to manage your skin as if you have a keloid constitution.
How should I manage my skin if I have a keloid constitution?
If you are determined to have a keloid constitution, it is best to avoid unnecessary injuries. If a wound does occur, it is important to receive appropriate treatment as soon as possible. Especially if surgery is required, informing the medical staff in advance that you have a keloid constitution can help reduce keloid recurrence.
Differences between Keloid Scars and Hypertrophic Scars
Both keloid scars and hypertrophic scars share the common characteristic of being raised above the surrounding skin surface. However, medically, they are distinguished as follows:
- Hypertrophic scars: Scars that are raised but confined to the size of the wound.
- Keloid scars: Scars that grow beyond the boundaries of the wound and invade the surrounding healthy skin.
Generally, keloid scars tend to be pinker, have clearer borders, are larger, and are more raised than hypertrophic scars. However, there are cases where keloids and hypertrophic scars cannot be perfectly distinguished, so if you have a tendency for scars to swell, it is wise to consider yourself to have a keloid constitution and manage your skin accordingly.
When is keloid treatment necessary?
Keloid scars generally require treatment when they are itchy or painful, or when they tend to grow rapidly within a short period. If these symptoms appear, professional diagnosis and treatment should be considered.
Initial Treatment Methods for Keloids
The typical initial treatment method for keloids is injection therapy in the affected area. After the injection, symptoms such as itching or pain in the keloid may subside, and a reduction in the size of the keloid can be expected.
