Macrophage activation syndrome (MAS) is a potentially life-threatening complication of rheumatic diseases. We report a unique case of a previously healthy 20-year-old female presenting with MAS as first presentation of systemic lupus erythematosus. Remission was achieved with hydroxychloroquine, intravenous methylprednisolone pulse followed by oral prednisolone and cyclosporine. However, the management of MAS is still challenging, and the mortality rate remains high.
