A 9-year-old girl and her 3-year-old brother were referred with a 15-day history of erythematous annular lesions on their faces (figure 1). Previous treatments with topical steroids had exacerbated the lesion; laboratory findings (full blood count, liver and renal function C-reactive protein) were unremarkable, and no other members of the family had similar skin lesions.
