On the other hand, livedo reticularis patients were significantly less likely to have venous thrombosis alone than patients without the skin condition.

In contrast, physicians caring for aPL-positive patients recognize other associated complications that include livedo reticularis, valvular heart disease, or thrombocytopenia, at times in the absence of more typical vascular or pregnancy events (Table 2).
Livedo reticularis in young patients with a history of vascular or pregnancy events should raise the possibility of aPL, although livedo is not specific for APS and may be a normal variant.
The spectrum of manifestations associated with APS is broad and includes, in addition to thrombosis and pregnancy morbidity, thrombocytopenia, livedo reticularis, cardiac valvular disease, and an acute syndrome of multiorgan thrombosis termed "catastrophic antiphospholipid syndrome.
