A 5-year-old girl presented in summer with an erythematous, scaly annular eruption in a malar distribution. She had no symptoms or signs of systemic lupus erythematosus. A diagnosis of subacute cutaneous lupus erythematosus was made on the basis of the clinical and histological features, positive anti-Ro antibody and a mildly elevated erythrocyte sedimentation rate. All other investigations, including complement studies, were normal. She has responded well to treatment with 0.5% alclometasone ointment and photoprotection.
