Adult-onset Still’s disease (AOSD) is a systemic inflammatory disorder. Its clinical presentation is similar to the systemic form of Juvenile idiopathic arthritis (JIA). In this case report we explore a young female 22 years after a diagnosis of JIA and 4 years after her diagnosis of AOSD who presents with systemic inflammatory symptoms. Some of the symptoms consistent with her previous diagnosis and some new. Specifically the new symptom of her diffuse lymphadenopathy lead to a differential of possible lymphoproliferative disease. After a biopsy and multiple admissions with unrelenting symptoms the patient was diagnosed with a flare of AOSD. We explore her case in depth with the question in mind: Does one diagnosed with JIA remain on long term therapy to avoid recurrent flares and progression to AOSD, and if so for how long?
