Evans syndrome is a rare autoimmune disease, characterized by at least two immune cytopenias, most frequently anemia and thrombocytopenia and rarely immune neutropenia. It has a variable clinical presentation and is rarely diagnosed in adults. It can be idiopathic or secondary to lymphoproliferative disease, infections, autoimmune diseases, drugs, and immunodeficiencies in about 50% of cases. It is characterized by a chronic, relapsing, potentially fatal course due to its hemorrhagic complications as well as complications associated with the long-term immunosuppressive treatment required to control the disease, such as infectious diseases, and cardiovascular and renal complications. Its prognosis depends on the underlying cause. Because of its rarity, the treatment is empirical, based mostly on case series and recommendations for the treatment of other immune cytopenias. The underlying disease and demographic characteristics also play an important role in choosing the treatment, which should be adapted individually to each patient. We present a case of an elderly patient with idiopathic autoimmune hemolytic anemia and thrombocytopenia, refractory to various treatment options.
