Vocal cord dysfunction.

A case of vocal cord dysfunction (VCD) is presented, followed by a discussion of the clinical characteristics, pathogenesis, diagnosis, and management of this disorder. Special emphasis is given to clinical pearls and pitfalls for the practicing allergist. VCD is a common condition that mimics asthma. Dyspnea, cough, and chest tightness are frequent manifestations of the disease. A high degree of clinical suspicion is required to recognize VCD and diagnosis is made most confidently by laryngoscopy. The mainstay of treatment for VCD is reassurance, speech therapy, and treatment of associated comorbidities including gastroesophageal reflux disease, postnasal drip syndrome, and psychiatric conditions.
