Thrombotic thrombocytopenic purpura in adult Still's disease
We describe 2 patients with adult Still's disease who developed thrombotic thrombocytopenic purpura (TTP) and were successfully treated. Although TTP has been associated with autoimmune diseases, usually with systemic lupus erythematosus or various forms of vasculitis, it has rarely been observed in patients with adult Still's disease. This uncommon coexistence of 2 clinical entities may indicate similar pathogenetic mechanisms.
