title: Nail staining from hydroquinone cream.
abstract: Topical hydroquinone is used in the treatment of a number of skin conditions. A 33-year-old male presented with brown discolouration of the fingernails following the application of 4% hydroquinone in sorbolene cream and 0.1% tretinoin cream to the face intermittently for 9 months. The discolouration resolved when the creams were ceased.
