Sneddon's syndrome: an antiphospholipid antibody syndrome?

A 44-year-old woman with livedo reticularis, multiple ischemic strokes, and transient ischemic attacks (Sneddon's syndrome) had antiphospholipid antibodies--the lupus anticoagulant and anticardiolipin antibodies. This patient provides support for the hypothesis that these antibodies are involved in the pathogenesis of this rare but now potentially treatable disorder.
