Extensive Soft Tissue Swelling in the Larynx and Hypopharynx of a Young Female Patient After Haloperidol Use: A Case Report on Angioneurotic Edema.

Angioneurotic edema is a potentially life-threatening condition characterized by the rapid swelling of subcutaneous and submucosal tissues of the upper respiratory and gastrointestinal tracts. It may result in laryngeal edema, thus obstructing the airway, with a potentially fatal outcome if not diagnosed early. An allergic reaction typically causes it, but certain drugs can induce or contribute to the development of angioneurotic edema in rare cases.
