[Adult onset Still's disease with normal level of serum ferritin].

We present a case of an adult onset Still's disease: a 51 year old men presented with one month history of high spiking fever, asymmetric migratory polyarthritis and a previous history of pharyngitis. The diagnostic was based upon clinical criteria and laboratory findings, and necessitated the exclusion of infectious, neoplastic, and other "autoimmune" disease. The systemic involvement in our case induced us to comment therapy with corticosteroid. Patients with systemic disease have a favorable prognosis, with only rare serious complications from the disease (pericarditis, tamponade, diffuse intravascular coagulation, amyloidosis, hepatic disease, and respiratory failure) or the treatment (infections, gastrointestinal bleeding etc.).
