A 39-year-old woman presented with a 7-month history of a nontender, enlarged, swollen upper lip. The swelling suddenly appeared 1 day after she received a tetanus booster. The patient denied new exposure to oral agents, including toothpaste, lip balm, foods, or cobalt-containing products. She gave no history of corticosteroid use, abdominal pain, blood or mucus in stools, shortness of breath, or weight loss. Prior to visiting the dermatology clinic, she was diagnosed as having chronic angioedema and treated with fexofenadine hydrochloride, 60 mg/d, without improvement. Her medical history was positive for hypothyroidism but otherwise unremarkable. Family history was noncontributory.
