Acquired C1 inhibitor deficiency associated with SLE / 대한내과학회지

ABSTRACT

Acquired C1 inhibitor deficiency is a rare syndrome which usually presents with episodes of angioedema. The association of lupus erythematosus and angioneurotic edema has been previously reported but is usually related to hereditary C1 inhibitor deficiency. Currently the relationship between acquired C1 inhibior deficiency and lupus erythematosus is being discussed. So we report the case of a previously healthy 28-year-old woman, who developed simultaneously and acquired angioneurotic edema and systemic lupus erythematosus.
