title: Chronic anemia and thrombocytosis as the initial presentation of Still's disease in an elderly patient.
abstract: Still's disease is very rare in elderly patients. We report a case of Still's disease in an elderly patient that had an atypical initial presentation. A 76-year-old woman developed unexplained chronic anemia and thrombocytosis. Three years later she had acute onset of high fever, arthritis, maculopapular rash, pleuritic chest pain, abdominal pain, lymphadenopathy and elevated erythrocyte sedimentation rate. Rheumatoid factor and antinuclear antibodies were negative. She responded favorably to prednisone and methotrexate treatment. Anemia and thrombocytosis as well as Still's disease manifestations resolved.
