Still's disease (SD) was described for the first time in children by George Still in 1896. It is characterized by a fever of approximately 39°C which continues for more than seven days, arthralgias or arthritis of two weeks duration or longer, and macular and/or maculopapular rash which is non-pruritic and salmon pink in color. Sore throat, lymph node swelling, hepatomegaly and/or splenomegaly with abnormal liver function studies, may also be present [3] . Typically, laboratory studies show an elevated ESR, which is accompanied by leukocytosis with the predominance of granulocytes. Normocytic normochromic anemia with hemoglobin values less than 10 g/dl and reactive thrombocytosis are seen in the majority of patients. Altered liver function studies are relatively common. However, liver biopsy findings are usually non-specific [4] .
