[Clinical manifestations associated with the presence of lupus anticoagulant].

The case of a woman with systemic lupus erythematosus with unusual clinical, cutaneous and biologic features and lupus anticoagulant is presented. According to the literature this association is not fortuitous: a new syndrome characterized by the presence of a subgroup of antiphospholipid antibodies has been recognized. The cutaneous symptoms of this syndrome include: leg ulcers, livedo reticularis, widespread cutaneous necrosis and distal cutaneous ischemia. In our patient a nearly complete picture of the clinical and biologic features of this syndrome, including a characteristic retinal vein thrombosis is present.
