A 40-year-old female presented with a several month history of rash on her chin, which was asymptomatic. She is otherwise healthy and has no other rashes.
A biopsy confirmed the clinical impression of cutaneous lupus. This particular lesion was mostly burnt out and will only partially improve with hydroxychloroquine therapy.
Differential Diagnosis: Morphea and lichen sclerosus are not usually seen on the face. Dermatophyte infections usually are more inflammatory and scaly. Vitiligo should be more depigmented, unlike what is seen here.
