[Vascular complications in systemic lupus erythematosus].

A 41-year-old woman is reported who had been observed and treated for 15 years for arterial and venous thrombotic episodes and in whom only in the 9th year of the disease systemic lupus erythematosus was diagnosed. During these 9 years the case was not meeting the diagnostic criteria of this disease. The possibility of transition of inactive collagen disease manifesting itself as thrombo-obliterative vasculitis into its active form is discussed.
