Adult onset Still′s disease: An uncommon etiology of non-resolving pneumonia

Abstract

Adult-onset Still's disease (AOSD) is a rare systemic inflammatory disorder of unknown etiology and pathogenesis, usually presenting with high spiking fever accompanied by several systemic manifestations. Pulmonary complications in AOSD are also rare. Only a few earlier pathologic reports exist describing AOSD with pulmonary involvement. AOSD presenting as non-resolving pneumonia is poorly reported in literature. We report one case of AOSD presented initially as non-resolving pneumonia. In this report, we conclude that every clinician must consider AOSD as a potential differential diagnosis of non-resolving pneumonia.
