title: Exogenous ochronosis in a Mexican-American woman.
abstract: Exogenous ochronosis resulting from the topical application of hydroquinone-containing bleaching creams has been reported to occur almost exclusively in black subjects, and only after use of high concentrations of hydroquinone (greater than 3 percent) for many years. A Mexican-American patient is described who experienced exogenous ochronosis after using 2 percent hydroquinone cream for less than six months.
