Asthma Boy is a clinic patient, a young child who is seen by Gregory House in the episode Pilot. He was played by child actor Dylan Basu. Asthma Boy had already been diagnosed with asthma and had been prescribed a steroid puffer by a previous doctor. He comes to the clinic with persistent breathing problems. However, at that moment, he realizes his primary patient has symptoms that may indicate vasculitis and that, if she does, steroids were the perfect choice. He rushes out of the exam room telling the mother that if she doesn't believe in steroids, she shouldn't believe in doctors either.
