The antiphospholipid antibody syndrome has been associated with various cutaneous manifestations, the most common of which may be leg ulceration. Cutaneous ulcers with clinical features suggestive of pyoderma gangrenosum have been reported in this setting only rarely. We report here two additional cases of the association between antiphospholipid antibody syndrome and pyoderma gangrenosum-like skin lesions. These patients suffered from the primary antiphospholipid syndrome. We suggest that clinicians assay for antiphospholipid antibodies when a clinical diagnosis of pyoderma gangrenosum is entertained.
