title: Persistent photosensitivity caused by musk ambrette.
abstract: Persistent photosensitivity developed in a man after use of an after-shave lotion containing musk ambrette. His eruption, present over ligh-exposed areas of the face, the "V" area of the neck, and the dorsa of the hands, has persisted for more than three years despite therapy. The patient demonstrated a minimal erythema after an ultraviolet B dose of 5 s, and was strongly ultraviolet A photosensitive to a 2% musk ambrette solution in petrolatum and to the after-shave lotion that contained musk ambrette. A persistent light reactivity induced by musk ambrette has most likely developed in this patient.
