title: Hereditary angioedema due to deficit of C1 esterase inhibitor.
abstract: A case of familial angioedema due to deficit of C1 esterase inhibitor is presented. The case had the following peculiarities: onset at a very early age (8 months); involvement, in some attacks, of the nasal mucosa with nasal obstruction and sinusitis manifestations; unusually long duration (as long as 9 days) of some of the localized edema. The absence of attacks during pregnancy was noted. The family study over 4 generations illustrated the dominant hereditary character of genetical transmission. Attention is drawn on two cases in the family in which the disease apparently skipped one generation from the point of view of clinical signs.
