Summary
IgA subtype antiphospholipid syndrome is a variant within the antiphospholipid syndrome
group. It is also associated with a significantly increased risk of thrombembolic
complications, as is the IgG antiphospholipid syndrome, IgM isotype. The clinical
picture on the skin is varied, ranging from livedo race-mosa to ulcers cruris and
disseminated vasculitic lesions. Especially the vasculitic changes can best be explained
by the properties of the immunoglobulin subtype. The addition of IgA antibodies and
a skin biopsy is often helpful for further diagnosis and differentiation of other
differential diagnoses.
