title: Riehl's melanosis: pigmented contact dermatitis caused by fragrances.
abstract: We report a case of a 27-year-old woman with a patchy, dark brown hyperpigmentation on the face. Patch tests were positive to lemon oil, geraniol, and hydroxycitronellal. A compact face powder that the patient used contained two of these chemicals. Hyperpigmentation disappeared within 6 months after the patient avoided contact with cosmetics containing these fragrances.
