Cough-variant asthma in children and adults: case reports and review.

Two cases of cough-variant asthma are presented, one in an adult and one in a child. We discuss the diagnosis, treatment, and course of this common, yet often unrecognized entity. The keys to diagnosis are a typical history, clinical suspicion, and subsequent response to bronchodilator therapy. Treatment of cough-variant asthma is no different from that of classic asthma.
