Although antiphospholipid antibodies have been detected in patients wi
th human immunodeficiency virus (HIV) disease, the clinical manifestat
ions of the antiphospholipid syndrome are extremely rare. We describe
a woman with acquired immunodeficiency syndrome (AIDS) and elevated an
tiphospholipid antibodies who developed necrotic skin lesions and was
subsequently shown to have antiphospholipid syndrome. This finding con
tradicts the general belief that such antibodies are not clinically si
gnificant in patients with HIV disease. We follow the report with a br
ief description of the antiphospholipid syndrome and its relation to A
IDS.
