What It Is

Defining Granuloma Annulare

→ Granuloma annulare (GA) is a chronic, benign skin condition that causes ring-shaped patches or raised bumps on the skin.

→ It occurs when the immune system causes inflammation in the skin’s dermis, leading to localized or widespread lesions.

→ While the exact cause is unknown, GA is often associated with autoimmune responses, diabetes, thyroid disease, or skin injury.

→ In Korea, dermatology clinics provide both medical treatments and cosmetic support therapies to manage symptoms and improve skin appearance.

Key Characteristics

• Circular or ring-shaped raised lesions
• Usually red, pink, purple, or skin-colored
• Commonly appears on hands, feet, elbows, knees, but may spread to other areas
• Can be localized, generalized, or subcutaneous
• Typically asymptomatic, but sometimes itchy or tender

Why It’s Done

Main Reasons for Seeking Care

➡ Cosmetic Concerns – Ring-shaped patches can be highly visible, especially on exposed areas.

➡ Discomfort – Some lesions may cause itching, tenderness, or burning.

➡ Chronic Nature – Although harmless, GA often persists for months to years without treatment.

➡ Underlying Health Concerns – Treatment may uncover or help monitor associated conditions like diabetes or thyroid issues.

➡ Emotional Relief – Improving skin appearance often boosts confidence and quality of life.

Alternatives

Non-Medical Options

• Observation → Many cases resolve on their own within months to years.
• Camouflage Makeup → Conceals visible patches temporarily.
• Moisturizers → Help reduce dryness and irritation.

Medical Alternatives

→ For patients seeking active treatment:

• Topical Corticosteroids → Reduce local inflammation.
• Intralesional Steroid Injections → Flatten stubborn lesions.
• Cryotherapy → Freezes small, localized patches.
• Laser Therapy → Targets pigmentation and lesion texture.
• Phototherapy (PUVA or NB-UVB) → Useful for widespread or generalized GA.
• Systemic Medications → Hydroxychloroquine, dapsone, or isotretinoin for resistant cases.

Preparation

Before Care and Treatment

➡ Dermatology Examination – A specialist evaluates lesion type, distribution, and severity.

➡ Biopsy – Sometimes performed to confirm diagnosis and rule out fungal infections or other skin diseases.

➡ Medical History Review – Screening for diabetes, thyroid disease, or autoimmune conditions.

➡ Allergy and Medication Review – Ensures safe prescription of steroids, immunosuppressants, or phototherapy.

➡ Expectation Setting – Patients are advised that GA often recurs and may require long-term monitoring.

How It’s Done

Common Treatment Methods in Korea

1. Topical Corticosteroids
→ First-line therapy for localized GA.

• Applied daily for several weeks.
• Helps reduce redness, swelling, and lesion size.

2. Intralesional Steroid Injections
→ Used for small but stubborn patches.

• Direct steroid injection into the lesion.
• Reduces inflammation and accelerates resolution.

3. Cryotherapy
→ Liquid nitrogen freezes and destroys affected tissue.

• Works best for small, isolated lesions.
• May cause temporary blistering.

4. Phototherapy
→ Narrowband UVB or PUVA light therapy is common in Korean dermatology clinics.

• Effective for generalized or widespread GA.
• Requires multiple sessions over several weeks.

5. Systemic Medications
→ Reserved for severe or resistant GA.

• Hydroxychloroquine, isotretinoin, dapsone, methotrexate may be prescribed.
• Monitored carefully due to potential side effects.

6. Laser Therapy
→ Fractional and pulsed-dye lasers used for pigmentation and redness control.

• Often combined with topical or injection therapies.

Recovery

Immediate Recovery

• Topical and Intralesional Steroids → May cause mild irritation, redness, or thinning with prolonged use.
• Cryotherapy → Healing occurs within 1–2 weeks with scabbing.
• Phototherapy → May cause mild redness or dryness after sessions.
• Systemic Medications → Require blood monitoring for long-term safety.

Long-Term Recovery

→ GA may resolve completely but has a tendency to recur in cycles.

→ With consistent care, patients achieve reduced lesion visibility, smoother skin, and longer remission periods.

→ Ongoing skincare routines with moisturizers and sun protection help maintain skin health.

Complications

Possible Risks

• Steroid Side Effects → Thinning of skin, stretch marks, or pigmentation changes with overuse.
• Cryotherapy Risks → Blistering, scarring, or hypopigmentation.
• Phototherapy Risks → Mild burning, premature aging with long-term use.
• Systemic Medication Risks → Eye changes (hydroxychloroquine), blood abnormalities (dapsone), liver or lipid issues (isotretinoin).
• Recurrence → Even after treatment, GA often returns, requiring ongoing care.
