A Case of Angioneurotic Edema of the Tongue and Oral Floor Associated with Angiotensin-Converting Enzyme Inhibitor

Abstract

Angiotensin-converting enzyme (ACE) inhibitors may rarely cause angioneurotic edema of the facial and oral region.
Some cases were associated with respiratory distress, and angioneurotic edema of the larynx is potentially life-threatening.
We report a case of angioedema in the tongue and oral floor that was probably caused by treatment with an ACE inhibitor. The patient was an 88-year-old woman. Her chief complaint was swelling of the tongue with respiratory distress.
There has been no recurrence of symptoms 1 year and 4 months after withdrawal of the ACE inhibitor.
