title: Livedo reticularis associated with dapsone therapy in a patient with chronic urticaria.
abstract: Dapsone is a drug commonly used in the treatment of various dermatological diseases. Here, we report the case of a 45-year-old female prescribed dapsone for chronic urticaria after which she developed extensive livedo reticularis in the limbs, abdomen, and trunk. The use of dapsone may be associated with a plethora of adverse effects including rash but livedo reticularis has been very rarely reported. Emphasis should be laid on the possible drug etiology in any patient who develops new signs and symptoms while on medications, even if it may not be supported by enough literature.
