Esophageal candidiasis is a rare disease in asthmatic patient,s using inhaled corticosteroid, but overall incidence is uncertain. While it does not cause significant morbidity, it may lead to diminished compliance t,o the antiasthma medi- cation. Here we experienced a case of bronchial ast,hma who developed esophageal candidiasis due to overuse of budesonide. Pat,ients requiring inhaled corticosteroids shoud be educated to prevent the local side effect such as esophageal cand idiasis.
