abstract：BACKGROUND:Hereditary angioedema with C1-inhibitor deficiency (C1-INH-HAE) is a rare, autosomal dominant disorder. The characteristic episodes of subcutaneous/submucosal edema formation may be preceded by erythema marginatum (EM) - the occurrence of a 'map-like' pattern on the skin. EM can occur as an isolated finding ...
