[Drug rash with eosinophilia and systemic cymptoms [DRESS syndrome] associated with sulfasalazine and human herpesvirus 6 infection successfully treated with steroid therapy]

We report a case of a 30-year-old man who developed a generalized erythematous skin eruption, fever, lymphadenopathy, hepatic cytolysis and eosinophilia probably due to sulfasalazine. Indirect immunofluorescence assay for Human herpesvirus-6 [HHV-6] was positive, supporting recent HHV-6 infection. The patient was successfully treated with dexamethasone. The case is reported with a review of the literature. DRESS syndrome mechanisms and management are also discussed
