Hereditary Angioedema in Female of Three Generations
Hereditary angioedema type III is a type of angioedema, affecting mainly females, without alteration of the level or function of C1 inhibitor, and is associated with exposure to increased levels of oestrogens. The authors present the case of a previously healthy 14-year-old girl observed with lip and face oedema with four days of evolution.
She had started an oral contraceptive about one week before. She had no new episodes of angioedema after stopping the oral contraceptive. In the family history, both the grandmother and great-grandmother had episodes of recurrent angioedema until menopause.
The authors intend to discuss a rare form of angioedema with an important impact on the patient’s quality of life.
The early diagnosis is important and should be based on clinical findings and a detailed family history.
