<unk>  is the most common type of chronic cutaneous<unk>  (CCLE), an autoimmune skin condition on the<unk>  erythematosus spectrum of illnesses. It presents with red, painful, inflamed and coin-shaped patches of skin with a scaly and crusty appearance, most often on the scalp, cheeks, and ears. Hair loss may occur if the lesions are on the scalp. The lesions can then develop severe scarring, and the centre areas may appear lighter in color with a rim darker than the normal skin. These lesions can last for years without treatment. Patients with systemic<unk>  erythematous develop<unk><unk>  lesions with some frequency. However, patients who present initially with<unk><unk>  infrequently develop systemic<unk> .<unk><unk>  can be divided into localized, generalized, and childhood<unk><unk> . The lesions are diagnosed by biopsy. Patients are first treated with sunscreen and topical steroids. If this does not work, an oral medication—most likely hydroxychloroquine or a related medication—can be tried.
