Systemic lupus erythematosus presenting as macrophage activation syndrome in an adult male

Macrophage activation syndrome (MAS) is a rare, life-threatening, hyperinflammatory state where there is a combination of fever with cytopenias, high ferritin, high aspartate transaminase, and high triglyceride levels. In adults, MAS infrequently occurs as a complication of systemic lupus erythematosus (SLE). SLE presenting as MAS is extremely rare in adults. We report a patient with MAS who presented with fever, rash, and high ferritin level (>2000).
