Adult-onset Still's disease in clinical practice of infectious diseases: A case report

Abstract

Adult-onset Still's disease is a rare autoimmune disorder accompanied by a triad of fever, exanthema, and arthralgia. In addition to this dominant presentation, it has a wide spectrum of clinical symptoms, with extensive involvement of multiple organs. Because of this, the diagnosis of adult-onset Still's disease remains one of exclusion and fulfilling sets of diagnostic criteria. We report on the case of a 20-year-old female who was initially treated for a suspected allergic reaction to a drug and then referred to an infectious disease specialist as fever of unknown origin accompanied with rash. This case highlights the challenges that clinicians face in differential diagnostic of Still's disease.
