[Still disease in adults]

Abstract

Adult onset Stills disease (ASD), an adult variant of systemic onset juvenile rheumatoid arthritis, is a rare disease entity. The diagnosis is solely a clinical one and often difficult. Clinical and laboratory features are not pathognomonic. The diagnosis of ASD has to be considered in patients with high spiking fever, transient rash, arthralgias, oligo- or polyarticular arthritis, leukocytosis, sore throat, lymphadenopathy and/or splenomegaly, liver dysfunction and high serum ferritin levels. We give a brief review of the clinical features, differential diagnosis, treatment and prognosis.
