A Diagnosis of Adult-Onset Still’s Disease after Multiple Urgent Care Visits

Abstract EN

A 34-year-old man with recent treatment and resolution of community-acquired pneumonia presents to the emergency department with protracted fever, rash, and sore throat.

Sustained fever and greater than two-fold increase in leukocytosis despite appropriate antibiotic therapy prompted hospital admission for infectious disease and rheumatologic evaluations which ultimately revealed adult-onset Still’s disease, a rare autoinflammatory disorder with potentially life-threatening complications.
