Résumé
Angioedema is a potentially life threatening condition and may be either inherited or acquired. The latter is rare with only a handful of cases reported in the world literature. Presenting complaints are often vague. Those most commonly described include swelling in the subcutaneous and submucosal tissues. Patients presenting with laryngeal edema have high mortality, and high clinical suspicion is necessary to avoid instrumentation, which can precipitate laryngeal spasm. We present a review of reported cases of hormonally induced hereditary angioedema, along with a report of a patient with acquired angioedema secondary to hormone replacement therapy. To the best of our knowledge, this case probably represents the first reported case of acquired angioedema secondary to hormone replacement therapy.
