Erythroderma
When Does Diffuse Red or Scaly Rash Need Derm Discussion?
A concise clinician guide for erythroderma, severe diffuse scaling, and admission-level skin burden.
Quick answer
Erythroderma Triage
- Derm discussion is reasonable when most of the skin surface is red or scaly, the patient is systemically ill, or inpatient topical regimen, biopsy, systemic therapy discussion, or CTCL evaluation may change care.
- Potential causes include psoriasis, eczema, drug eruption, CTCL/Sezary, crusted scabies, and blistering disease. *
- Stable chronic eczema or psoriasis flare without systemic instability or admission-level burden is different.
Derm discussion is reasonable when
Higher-Yield Consult Context
- Most body surface area is red, scaly, painful, swollen, or difficult to manage.
- Fever, hypothermia, edema, infection risk, high-output physiology, severe pruritus, lymphadenopathy, or inability to maintain skin care.
- Biopsy, inpatient topical regimen, wet wraps, systemic therapy discussion, or CTCL/Sezary concern may change management.
Workup or other service first when
Better First Step
- The patient is unstable and needs ED/ICU stabilization.
- Stable chronic dermatitis or psoriasis can be managed through outpatient or standard pathways.
- Medication timeline, exposure history, immune status, and photos are missing and no inpatient decision changes.
Common pitfall
Keep the Question Specific
Erythroderma is a pattern, not a diagnosis. The page should push clinicians to ask what inpatient decision Derm would change.
FAQ
Clinician Questions
What is the key inpatient question?
Whether Derm changes diagnosis, biopsy, skin-care regimen, systemic therapy discussion, malignancy/CTCL evaluation, or disposition.
When is this lower acuity?
Stable chronic rash without systemic illness, admission-level burden, or diagnostic uncertainty changing disposition is usually lower acuity.
What details help?
Body surface involved, edema, fever/hypothermia, pruritus, pain, lymphadenopathy, medication timeline, immune status, and prior skin disease.
