What is Acral Peeling Skin Syndrome?
Acral Peeling Skin Syndrome (APSS) is a rare genetic skin disorder characterized by painless peeling of the skin on the hands and feet. The condition is non-inflammatory and usually present from birth or early childhood. It is caused by mutations in the TGM5 gene, which affects the skin’s ability to stick together properly.
What Causes Acral Peeling Skin Syndrome?
APSS is caused by genetic mutations and is inherited in an autosomal recessive pattern, meaning both parents must carry the defective gene for a child to be affected.
Risk Factors:
- Genetic mutations in the TGM5 gene – Affects skin cohesion
- Family history of APSS – Increased risk if both parents are carriers
- Friction and moisture exposure – Can worsen skin peeling
What Are the Symptoms of Acral Peeling Skin Syndrome?
The main symptom is superficial skin peeling, especially after exposure to water, heat, or friction.
Common Signs & Symptoms:
- Painless peeling of the outermost skin layer (epidermis)
- Affects hands, feet, and fingers – Sometimes other body parts
- Triggered by moisture, heat, or rubbing
- Mild redness or irritation in some cases
- No scarring or long-term damage
How Is Acral Peeling Skin Syndrome Diagnosed?
A diagnosis is based on clinical symptoms, family history, and genetic testing.
Diagnostic Tests:
- Physical Examination – Dermatologist evaluates skin peeling patterns
- Skin Biopsy – Examines skin structure under a microscope
- Genetic Testing – Confirms mutations in the TGM5 gene
What Are the Treatment Options for Acral Peeling Skin Syndrome?
There is no cure for APSS, but symptoms can be managed with skincare and lifestyle adjustments.
1. Skin Care Management
- Moisturizers & Emollients – Prevent excessive dryness
- Avoid hot water and excessive friction – Reduces peeling episodes
- Mild soaps & hypoallergenic products – Prevents irritation
2. Topical Medications
- Petroleum jelly or barrier creams – Protects skin from peeling triggers
- Mild corticosteroids (if irritation occurs) – Reduces inflammation
3. Genetic Counseling
- Recommended for families with a history of APSS to assess risk factors
Can Acral Peeling Skin Syndrome Cause Complications?
APSS is not life-threatening, but it can cause:
- Increased skin sensitivity
- Mild irritation or discomfort
- Social or cosmetic concerns due to visible peeling
