Author and Disclosure Information
Lupus erythematosus tumidus (LET) is a unique subset of chronic cutaneous lupus erythematosus (CCLE) that generally presents as urticarialike papules and plaques with induration and erythema on the face, trunk, and upper extremities. Lesions rarely present on the scalp or below the waist. We report a unique case of LET on the scalp of a woman that presented clinically as alopecia areata. Resistance to the standard treatment for alopecia areata prompted a biopsy that proved the diagnosis.
Practice Points
- Lupus erythematosus tumidus (LET) of the scalp can mimic alopecia areata on clinical presentation.
- A unique variant of chronic cutaneous lupus erythematosus, LET presents in sun-exposed areas without any corresponding systemic signs.
- Lupus erythematosus tumidus may respond well to antimalarial drugs.
