An 8-year-old girl presents with a six-week history of an erythematous linear lesion on her left thigh (Figure). It is slightly raised and scaly but not itchy. The girl has been previously well and the lesion developed quite suddenly, over a few days, and has persisted despite treatment with mometasone furoate 0.1% cream and miconazole cream.
