Thrombotic thrombocytopenic purpura as an initial presentation of limited systemic sclerosis

Thrombotic thrombocytopenic purpura (TTP) is a rare complication of scleroderma (systemic sclerosis, SSc). In the 5 reports documenting the association of TTP and SSc, the TTP syndrome developed on a background of well established SSc. We describe a 51-year-old woman with a 5 month history of an evolving connective tissue disease syndrome who presented initially with TTP, followed 4 months later by limited cutaneous SSc and Raynaud's phenomenon.
