title: A rare trigger for macrophage activation syndrome.
abstract: Macrophage activation syndrome (MAS) is a disorder characterized by increased activation of mononuclear cells leading to phagocytosis of blood cell precursors in the bone marrow. We describe a case of MAS triggered by disseminated histoplasmosis occurring in a patient with Still's disease on long-term treatment with adalimumab.
