Skin Rash and Fever of Unknown Origin A Diagnostic Challenge.

We report a clinical case of adult-onset Still's disease. In addition to the imaging features of the case, the following aspects are also briefly described: clinical presentation (prolonged fever associated with migratory polyarthritis and skin rash), treatment performed (resort to anti-inflammatory and corticoid), and clinical evolution of the patient after having performed the adult-onset. The treatment was found to be appropriate as the patient presented a favourable clinical evolution. LEARNING POINTS: Skin manifestations are associated with systemic diseases.Persistent febrile syndromes typically occur in young age.Adult-onset Still's disease is generally considered as a diagnosis of exclusion, as it presents with a combination of non-specific symptoms.
