Epidermolysis Bullosa - Symptoms, Causes & Treatment
Medically reviewed by Dr. Anand S. Urhekar, MD, MD Pathology, Clinical Advisor · Last updated July 2026
A group of rare inherited disorders in which the skin is extremely fragile and blisters or tears in response to minor friction. Severity ranges from blistering limited to hands and feet through to severe generalised forms with scarring, contractures, internal involvement and increased skin cancer risk.

Quick Answer
Epidermolysis bullosa is a group of inherited conditions causing skin so fragile that minor friction produces blisters and tears — hence the term 'butterfly children'. The main types are simplex, junctional, dystrophic and Kindler syndrome, varying from mild hand and foot blistering to severe generalised disease. There is no cure; care centres on skilled wound management, pain control, nutrition and specialist multidisciplinary support.
Symptoms
- Blisters and skin tears after minor friction or trauma
- Fragile skin on hands, feet and pressure points
- Scarring, fusion of fingers and contractures in dystrophic types
- Nail loss and dental abnormalities
- Mouth, throat and gut involvement in severe forms
Causes & Risk Factors
- Inherited mutations in structural skin proteins (keratins, laminin, collagen VII)
- Autosomal dominant or recessive inheritance depending on subtype
- Diagnosis confirmed by skin biopsy with immunofluorescence mapping and genetic testing
Treatment & Management
- Specialist non-adherent dressings and meticulous wound care
- Blister lancing technique to prevent extension, leaving the roof intact
- Pain management and itch control
- Nutritional support and dental care
- Multidisciplinary specialist centre input; emerging gene and cell therapies
- Regular surveillance for squamous cell carcinoma in dystrophic EB
When to See a Doctor
Newborns with unexplained blistering or missing skin need urgent specialist assessment. Established patients should seek review for non-healing wounds, changing lesions, infection or poor nutrition.
Frequently Asked Questions
Is there a cure for epidermolysis bullosa?
Not yet. Care is supportive and highly specialised, though gene therapy, cell therapy and topical gene-transfer products have begun to reach clinical use for specific subtypes.
Why is skin cancer surveillance needed?
Chronic wounds and scarring in recessive dystrophic EB carry a substantially raised risk of aggressive squamous cell carcinoma from young adulthood, so regular skin examination is part of routine care.
