DRESS syndrome - A dermatological emergency - Sulfasalazine-related acute drug reaction case report.

Drug reaction with eosinophilia and systemic symptoms (DRESS syndrome) or drug-induced hypersensitivity syndrome (DIHS) is a severe skin reaction associated with general symptoms and mortality reaching up to 10% of cases. DRESS/DIHS is one of the few dermatological emergencies which need to be taken into consideration when dealing with a patient with acute exanthema and systemic symptoms like: fever, lymphadenopathy, muscle pain, hepatosplenomegaly, abnormal blood count results and systemic inflammation. The aim of this article is to summarize the literature finding regarding this dermatological emergency and present the case of a 42-year-old male suffering from DRESS syndrome as a consequence of sulfasalazine intake due to an inflammatory bowel disease, who was effectively treated with oral prednisolone and immediate drug withdrawal.
