A foreign body aspiration in a preschool child mimicking a multitrigger wheezing: a case report and review of the literature.

We report a child with a history of recurrent episodes of wheezing. At 3 months of age, the frequency of these episodes began to increase. Wheezing was associated with persistent cough and dyspnea with nocturnal awakening. The skin prick test was positive for pollen and pet dander. Airway endoscopy revealed the presence of a peanut, which obstructed the left main bronchus. Chronic cough and recurrent wheezing with symptoms between acute exacerbations could be signs not only of asthma but also of other disorders. Therefore, coexisting conditions should be evaluated whenever symptoms seem to be unusually severe or frequent.
