Keloids: Causes, Symptoms, and Treatment

Keloids: Causes, Symptoms, and Treatment


Keloids(also known as cicatrice) are a common dermatological condition characterized by the overgrowth of scar tissue, extending beyond the original wound or incision. They can be cosmetically distressing and cause discomfort or itching in affected individuals. In this article, we will delve into the world of cicatrice, exploring their causes, symptoms, risk factors, and available treatment options. Understanding keloids is essential for both those experiencing them and those seeking information on prevention and management.


Understanding Keloids

cicatrice are a type of raised scar tissue that forms at the site of an injury or wound. Unlike typical scars that gradually fade and flatten over time, cicatrice can continue to grow, extending beyond the boundaries of the original injury. These raised, firm, and often shiny growths are typically colored in a range from pink to dark brown. cicatrice can develop on any part of the body but are most commonly found on the chest, shoulders, earlobes, and neck.

Causes of Keloids

The exact cause of cicatrice is not fully understood, but several factors contribute to their development, including:

  1. Genetics: A family history of cicatrice is a significant risk factor. Individuals with a genetic predisposition are more likely to develop keloids.
  2. Injury or Surgery: Keloids often develop in response to injuries, such as burns, cuts, surgical incisions, or traumatic wounds. Even minor skin injuries can trigger their formation.
  3. Skin Type: People with darker skin, particularly those of African, Asian, or Hispanic descent, are more prone to keloid formation.
  4. Hormonal Factors: Hormonal changes during pregnancy can increase the likelihood of keloid development. Hormone therapy and puberty can also influence their formation.
  5. Inflammation: Chronic inflammation at the site of an injury or wound can contribute to keloid formation.

Symptoms of Keloids

Keloids are primarily identified by their distinctive appearance. Common symptoms and characteristics of cicatrice include:

  1. Raised, Firm Texture: cicatrice have a raised, firm texture, often extending beyond the boundaries of the original injury.
  2. Color Variations: They can appear pink, red, brown, or darker than the surrounding skin.
  3. Itching and Pain: cicatrice may cause itching, pain, or discomfort, especially when they grow or come into contact with clothing or jewelry.
  4. Cosmetic Concerns: The presence of cicatrice can be cosmetically distressing, particularly when they develop on visible areas of the body.


Diagnosing keloids is usually straightforward based on their clinical appearance and history of a preceding injury or surgical procedure. Healthcare providers may examine the keloid and ask about the patient’s medical history. In some cases, a skin biopsy may be performed to confirm the diagnosis and rule out other skin conditions.

Treatment and Management

Several treatment options are available for managing cicatrice, although their effectiveness can vary depending on the individual and the keloid’s size and location. Treatment approaches include:

  1. Corticosteroid Injections: Injections of corticosteroids directly into the keloid can help reduce inflammation and flatten the raised tissue. Multiple sessions may be required.
  2. Silicone Gel or Sheets: The application of silicone gel or sheets over the keloid can help soften and flatten the scar over time. This method is often used as an adjunct to other treatments.
  3. Cryotherapy: Cryotherapy involves freezing the keloid with liquid nitrogen to reduce its size and prominence.
  4. Laser Therapy: Laser therapy can be effective in reducing redness and flattening the keloid. It may require multiple sessions.
  5. Surgical Removal: Surgical excision is an option for larger cicatrice but may carry a risk of recurrence. To reduce the likelihood of recurrence, post-operative treatments like corticosteroid injections or radiation therapy are often recommended.
  6. Radiation Therapy: Radiation therapy may be used after surgical removal to minimize the chances of keloid regrowth.
  7. Pressure Dressings: Pressure dressings or silicone gel pads can help flatten cicatrice, particularly when applied soon after injury or surgery.
  8. Interferon Therapy: Interferon, a type of medication, has been used to treat cicatrice, although its effectiveness can vary.

It’s important to note that keloids may recur even after treatment. Therefore, close follow-up with a healthcare provider is essential to monitor and manage their progress.

Treatment and management of keloids can be challenging due to their tendency to recur and vary in response to different interventions. Here are key points related to the treatment and management of cicatrice:

  1. Early Intervention: Early treatment is often more effective in managing cicatrice . It’s important to address cicatrice as soon as they start to develop, as smaller keloids are generally more responsive to treatment.
  2. Corticosteroid Injections: Corticosteroid injections are a common first-line treatment for cicatrice. These injections help reduce inflammation and can flatten the keloid. Several sessions may be required, typically spaced a few weeks apart.
  3. Silicone Gel or Sheets: The use of silicone gel or sheets can help soften and flatten cicatrice. These products are applied directly to the keloid and should be used consistently for several months to see results.
  4. Pressure Dressings: Pressure dressings, also known as compression garments, are often recommended after surgery or other treatments to minimize keloid recurrence. They help to flatten the scar tissue.
  5. Cryotherapy: Cryotherapy involves freezing the keloid with liquid nitrogen. This treatment can reduce the size and color of the keloid but may require multiple sessions.
  6. Laser Therapy: Laser therapy is an option for reducing the redness and flattening cicatrice. It’s typically used for smaller cicatrice and may require multiple sessions.
  7. Radiation Therapy: Radiation therapy is sometimes used after surgical removal to prevent keloid recurrence. It can be an effective way to reduce the chances of regrowth.
  8. Surgical Excision: Surgical removal of the keloid is an option, particularly for larger cicatrice. However, it should be done with caution, as surgery can trigger keloid formation. Post-operative treatments like corticosteroid injections or radiation therapy are often recommended to minimize recurrence.
  9. Interferon Therapy: Interferon, a type of medication, has been used to treat cicatrice, particularly when other treatments have not been effective. However, its use is less common due to potential side effects.
  10. Combination Therapies: In some cases, a combination of treatments may be the most effective approach. For example, surgical removal followed by radiation therapy or corticosteroid injections may be recommended.
  11. Regular Follow-up: Close follow-up with a healthcare provider is crucial to monitor the keloid’s progress and make adjustments to the treatment plan if necessary.
  12. Patient Education: Providing patients with education about keloid management, including expectations, potential side effects, and the importance of adherence to treatment regimens, is essential.
  13. Lifestyle Modifications: Avoiding activities that may cause friction or irritation to the keloid, such as excessive sun exposure or tight clothing, can help in management.
  14. Prevention: Prevention is essential, especially for individuals at higher risk due to genetics or prior keloid formation. Preventive measures may include early treatment of injuries or surgical wounds with methods like silicone sheets.
  15. Psychological Support: cicatrice can be emotionally distressing due to their appearance. Offering psychological support and counseling to individuals with cicatrice can help them cope with the condition and improve their quality of life.

In conclusion, cicatrice can be challenging to manage, but a variety of treatment options are available. The choice of treatment should be tailored to the individual, the size and location of the keloid, and the likelihood of recurrence. Close collaboration with a healthcare provider and adherence to treatment recommendations are key to successful keloid management and minimizing their impact on one’s life.


Keloids are a unique type of raised scar tissue that can develop in response to injuries or surgical procedures. While they are not typically harmful to one’s health, keloids can be cosmetically distressing and cause discomfort. Understanding the factors contributing to keloid formation and the available treatment options is essential for individuals affected by this condition. Seeking medical advice and early intervention can help manage and improve the appearance of keloids, ultimately enhancing the quality of life for those who experience them.
