Differential Diagnosis & Pitfalls
- Urticarial vasculitis – EAE lesions are larger.
- Subacute cutaneous lupus erythematosus – EAE is not photosensitive and is not scaly.
- Tumid lupus
- Erythema annulare centrifugum – Typically has trailing scale.
- Tinea corporis – Look for scale and do a confirmatory potassium hydroxide (KOH) preparation.
- Erythema gyratum repens
- Erythema multiforme – Typically these lesions are smaller and more peripheral.
- Erythema marginatum
- Necrolytic migratory erythema – There are prominent erosions and/or bullae at active borders.
- Urticarial phase of bullous pemphigoid
