Keloid Scars

Also known as: Keloids · Cheloids · Fibroid Tumors of the Skin · Overgrown Scars

Definition

A Keloid Scar is an abnormal, overgrown fibrous tissue that forms at the site of a healed skin injury. Unlike normal scars or hypertrophic scars, keloids grow beyond the boundaries of the original wound, invading surrounding healthy skin. They are characterized by an excessive accumulation of extracellular matrix proteins, particularly collagen, resulting from a dysfunction in the wound healing process. (AAD, PAPRAS)

Keloids typically present as raised, firm, rubbery, or nodular lesions that can range in color from flesh-colored to pink, red, or dark brown. They are often accompanied by symptoms such as itching, pain, and tenderness. The most common anatomical sites for keloid formation include the chest, shoulders, upper back, earlobes, and face. While benign, they can cause significant physical discomfort and cosmetic concern. (NCBI)

Geography and Climate

In the Philippines, the tropical climate, characterized by high temperatures and high humidity, presents specific challenges for patients with keloid scars. Increased sweating (perspiration) can lead to skin irritation, itching, and inflammation around keloids, particularly those located on the chest, shoulders, and back.

The high heat can also make wearing occlusive silicone gel sheets—a common non-invasive treatment—uncomfortable, leading to reduced patient compliance. Local dermatologists and plastic surgeons adapt treatment protocols by recommending lightweight silicone gels that dry quickly, or scheduling clinical treatments like intralesional corticosteroid injections during cooler seasons. Patients are advised to keep keloid-prone areas clean, dry, and protected from friction in humid conditions.

Demographics

Keloids are more common in individuals with darker skin pigmentation, with a higher prevalence observed among populations of African, Hispanic, and Asian descent. In the Philippines, the majority of the population has Fitzpatrick skin phototypes III, IV, or V, which are associated with a higher risk of keloid formation compared to lighter skin types.

The condition can develop at any age but is most frequently diagnosed in individuals aged 10 to 30. This demographic group is more active and prone to skin injuries, acne, and body piercings. Keloids often form following minor skin trauma, such as ear piercing, surgical incisions, vaccinations (like the BCG vaccine), and inflammatory skin conditions like acne vulgaris. There is also a genetic component, as individuals with a family history of keloids are more likely to develop them.

Economy and Industry

The treatment and management of keloid scars represent a stable sector within the dermatology and plastic surgery markets in the Philippines. Due to the chronic nature of keloids and their high rate of recurrence, patients often require multiple sessions of combination therapies over several months or years.

The economic cost includes expenses for topical silicone products, intralesional triamcinolone acetonide injections, cryosurgery, and advanced therapies like laser treatments (such as pulsed dye lasers) or surgical excision combined with superficial radiation therapy. This demand supports a market for specialized dermatological pharmaceuticals, medical devices, and clinic services.

Transportation and Infrastructure

Access to advanced keloid treatments depends on the medical infrastructure available in major urban centers. Specialized clinics and tertiary hospitals in Metro Manila, Metro Cebu, and Metro Davao offer combination treatments, including surgical excision and localized radiotherapy, which require specialized oncology and surgical facilities.

For patients in provincial areas, transport networks are necessary to access regional hospitals for specialized treatments. Telemedicine has become a useful tool, allowing patients to consult with specialists for initial evaluations and post-treatment monitoring, reducing the need for frequent travel during long-term management.

Culture and Tourism

In the Philippines, clear skin is highly valued, and visible keloid scars, particularly on the face, neck, or chest, can cause self-consciousness and emotional distress. This cultural value drives patients to seek treatment to reduce the size and appearance of the scars. Reconstructive and aesthetic specialists work to educate the public about the risks of self-treatment or using unverified home remedies.

The country’s medical tourism sector attracts patients seeking scar revision and reconstructive surgeries. Board-certified plastic surgeons and dermatologists offer advanced keloid management plans at a lower cost than in Western countries, drawing international visitors and returning overseas Filipinos.

Government and Administration

The Food and Drug Administration (FDA) of the Philippines regulates all medications, medical devices, and topical products used for keloid treatment. Corticosteroids like triamcinolone acetonide, commonly used for intralesional injections, are prescription-only drugs and must be registered with the FDA to ensure quality and safety.

The DOH monitors safety standards in hospitals and ambulatory clinics where surgical scar revisions are performed. Professional organizations, such as PAPRAS and the Philippine Board of Dermatology, establish guidelines for safe practice, helping protect patients from substandard treatments in unlicensed facilities.

Education and Healthcare

Educational programs for plastic surgeons and dermatologists in the Philippines place a strong emphasis on wound healing and scar management. Accredited training programs cover the prevention and treatment of abnormal scars, training clinicians to recognize early signs of keloid formation and intervene promptly.

Medical education emphasizes the importance of avoiding unnecessary cosmetic surgeries in patients with a known history of keloids. When surgery is necessary, surgeons are trained to use tension-free closure techniques and initiate immediate post-operative therapies, such as silicone gel application or early steroid injections, to minimize the risk of recurrence.

Examples and Analogies

An analogy for a keloid scar is a building contractor who continues to pour concrete long after the foundation is complete. In normal wound healing, the body produces collagen to close the wound, stopping once the skin is repaired. In keloid formation, the “stop” signal is missing, and the cells continue to produce collagen, building an overgrown mound of scar tissue that spills over onto the surrounding healthy skin.

A concrete example is a keloid that forms on the earlobe following a piercing. A small tear in the skin triggers an overproduction of collagen. Over several months, a firm, pea-sized nodule develops around the piercing site. It can grow larger than the earlobe itself, causing discomfort and requiring medical intervention like surgical excision combined with pressure earrings.

Usage Scenarios

1. Intralesional Steroid Therapy

A 24-year-old female in Manila develops a raised, itchy keloid scar on her shoulder following a vaccination. She consults a dermatologist, who recommends a series of intralesional triamcinolone acetonide injections spaced four weeks apart. The treatment helps flatten the scar and relieve the itching.

2. Surgical Excision with Adjuvant Therapy

A 35-year-old male in Cebu has a large keloid on his chest that has not responded to topical gels. A plastic surgeon performs a surgical excision using tension-free sutures, followed immediately by low-dose steroid injections and the use of silicone sheets to prevent the keloid from recurring.

Strategies

Apply medical-grade silicone gel or silicone sheets to healing wounds as soon as the skin closes to help regulate collagen production and prevent scar overgrowth.
Keep keloid-prone areas clean and dry, especially during hot and humid weather, to minimize skin irritation and itching.
Protect healing scars from direct sunlight by using clothing or sunscreen, as UV exposure can darken the scar tissue.

Security and Safety Measures

Avoid unnecessary body piercings, tattoos, or elective cosmetic surgeries if you have a personal or family history of keloid scars.
Do not attempt to cut, freeze, or self-treat keloids at home, as this can cause infection and trigger aggressive regrowth, making the scar larger.
Ensure that any invasive scar treatment, such as surgical excision or steroid injection, is performed by a board-certified plastic surgeon or dermatologist.

Historical Context

The clinical approach to keloid scars has transitioned from simple surgical removal—which often resulted in high rates of recurrence—to multi-modal combination therapies. Historically, keloids were difficult to treat, and surgery alone frequently triggered larger regrowth.

In the Philippines, the integration of intralesional steroids, cryotherapy, and silicone gel technologies has improved treatment outcomes. Modern protocols focus on early intervention and tension-free wound closure, allowing local clinicians to manage keloid scars more effectively in Asian skin phototypes.

Challenges and Controversies

High Rate of Recurrence

The primary challenge in keloid management is the high rate of recurrence, which can reach up to 50% or higher for certain treatment types. There is ongoing discussion in the medical community regarding the most effective combination of adjuvant therapies, such as the timing of steroid injections following surgical excision and the use of localized radiation.

Access to Specialized Therapies

While basic treatments like steroid injections are widely available, advanced therapies like pulsed dye lasers and localized radiation therapy are concentrated in major urban hospitals. Accessing these combined treatments can be difficult and expensive for patients living in rural provinces.
