What is erythroderma?
Erythroderma is a rare but serious skin condition that causes widespread redness, inflammation, and peeling across much of the body. It is also known as exfoliative dermatitis.
When large areas of skin become damaged, the body can lose fluids, proteins, and heat more easily. Because of this, erythroderma may require urgent medical treatment, especially if symptoms are severe.
Several health conditions and triggers may lead to erythroderma. Common causes include chronic skin disorders such as psoriasis or eczema, reactions to certain medications, and some types of cancer, including lymphoma. In some people, the exact cause is never identified.
Symptoms
Erythroderma can develop quickly or gradually over time. Symptoms often begin in smaller areas before spreading across the body.
Common symptoms include:
- Widespread red or inflamed skin
- Peeling or scaling skin
- Severe itching or burning
- Thickened or crusted skin
- Fever or chills
- Swollen lymph nodes
- Feeling tired or unwell
- Fluid loss or dehydration
How is it diagnosed?
A healthcare provider will examine your skin and review your symptoms, medical history, and any recent medication changes. Because many conditions can cause widespread skin inflammation, testing may be needed to find the underlying cause.
Diagnosis may include:
- A physical skin exam
- Blood tests
- A skin biopsy, where a small sample of skin is tested in a lab
These tests help providers rule out infection, medication reactions, or other medical conditions.
How is it treated?
Treatment focuses on stabilizing the body, protecting the skin, and treating the cause of the condition. Severe cases may require care in the hospital.
Treatment options may include:
- Stopping medications that may be triggering symptoms
- Treating underlying skin conditions or cancers
- IV fluids to prevent dehydration
- Nutritional support
- Moisturizers, ointments, and protective dressings
- Medicines to reduce inflammation
- Antibiotics if infection occurs
Recovery depends on the cause and how severe the condition becomes. Some people improve within weeks, especially when a medication reaction is identified early. Others may need ongoing care for chronic skin disease.
