Abstract
OBJECTIVE
Carcinoids are low-grade, slow growing malignant tumors in the bronchi usually producing symptoms secondary to bronchial obstruction. We describe a case of 25-year-old woman who was initially diagnosed with asthma.
METHOD
Case report.
RESULTS
Because of exacerbation and unresponsiveness to proper asthma treatment she was referred to spirometry, which showed low values of forced expiratory volume in 1 second. The shape of inspiratory limb of flow volume curve suggested an obstruction in the main bronchus or in the trachea. Further bronchoscopy revealed a tumor of the right main bronchus with characteristic histological features for carcinoid.
CONCLUSIONS
Both the inspiratory curve and the expiratory part of the flow-volume loop should be evaluated in patients being evaluated for asthma. If there are changes in the shape of the inspiratory limb suggesting an obstruction, CT and/or bronchoscopy should be considered.
