Vocal cord dysfunction in an asthmatic child: case report

Acute functional narrowing of the glottis frequently leads to an inappropriate diagnosis of asthma. Only 2 cases have been reported of patients with asthma and concomitant vocal cord dysfunction. We present the case of an adolescent boy with asthma, who exhibited a worsening of wheezing and a reduction in peak expiratory flow rate out of proportion to symptoms due to a vocal cord dysfunction.
