Diffuse arterial involvement in temporal arteritis is well known but the intimate mechanisms of vasculopathy is unknown. Recently the presence of anticardiolipin antibodies (aCL) has been recognized in giant cell arteritis. We report two cases of temporal arteritis with diffuse arterial involvement associated with aCL (axillary arteries in the two cases associated with femoral arteries in one). During corticosteroid and anticoagulant therapy, a rapid improvement was noted with regression of upper-limb ischemia. One month later, the aCL were absent. These cases confirm the presence of aCL in giant cell arteritis with diffuse arterial involvement. These antibodies might imply severe vascular damage and could play a role in pathogenesis of the vasculopathy of temporal arteritis. Their presence suggests the necessity of anticoagulant therapy at the beginning of corticosteroid therapy.
