Acne Keloidalis Nuchae

While the exact cause of keloid scars is unknown, it’s believed to be related to an overproduction of collagen during the healing process. Certain factors can increase your risk of developing

Symptoms

Characteristics of Keloid Scars

• Raised and Thickened Scar Tissue: Keloid scars are often raised, firm, and larger than the original wound.
• Irregular Shape: They can be lumpy, ridged, or claw-like.
• Color Variation: Keloids can be red, pink, brown, or purple.
• Itchiness and Discomfort: Many people experience itching, burning, or tenderness around the scar.
• Slow Growth: Keloids can continue to grow for months or even years after the initial injury.

Causes

Causes of Keloid Scars

• Overproduction of Collagen: An overactive wound healing process leads to excessive collagen production, resulting in raised, thick scars.
• Genetic Predisposition: People with a family history of keloids are more likely to develop them.
• Skin Color: Individuals with darker skin tones are more prone to keloid scarring.
• Type of Injury: Deeper injuries and infections can increase the risk of keloid formation.

Risk Factors

• Skin Color: People with darker skin tones, particularly those of African, Asian, and Hispanic descent, are more prone to keloid scarring.
• Family History: A family history of keloids increases your risk of developing them.
• Age: Young adults, especially those between the ages of 10 and 30, are more susceptible.
• Type of Injury: Deeper injuries, such as burns, surgical incisions, and piercings, have a higher risk of keloid formation.
• Location of Injury: Certain body areas, such as the shoulders, chest, and earlobes, are more prone to keloid scarring.

Complications

• Pain and Discomfort: Keloids can be itchy, painful, or tender.
• Psychological Distress: The appearance of keloids can lead to self-consciousness and negative body image.
• Infection: While rare, keloids can become infected, especially if they are irritated or scratched.

Prevention

• Proper Wound Care:
  • Keep wounds clean and moist.
  • Use gentle soap and water to clean the wound.
  • Apply a thin layer of petroleum jelly or silicone gel.
  • Cover the wound with a sterile bandage.
  • Avoid picking at scabs or scratching the wound.
• Minimize Skin Trauma:
  • Avoid unnecessary skin piercings, tattoos, and surgical procedures.
  • Be cautious with minor injuries, such as cuts and scrapes.
• Sun Protection: Protect scars from sun exposure, as UV rays can darken them and make them more noticeable.
• Pressure Therapy: Using pressure garments or silicone gel sheets can help flatten the scar and reduce its size.

When to see a doctor

• A new, raised scar develops—especially if it’s growing rapidly or causing discomfort.
• An existing scar begins to enlarge or change color, which could indicate a worsening keloid.
• You’re experiencing significant discomfort or itching.
• You’re concerned about the appearance of the scar and want to explore treatment options.

Treatment Options for Keloids

• Corticosteroid Injections: Reduce inflammation and soften the scar tissue.
• Silicone Gel Sheets: Help flatten and soften the scar.
• Laser Therapy: Reduces the redness and thickness of the scar.
• Cryotherapy: Freezes the scar tissue to shrink the keloid.
• Surgery: In some cases, surgical removal is considered, though there is a risk of recurrence.
