Case of uncontrolled asthma with Ceriporia lacerata-related broncholithiasis.

Abstract

An 81-year-old Japanese male patient was treated for asthma. He complained of persistent cough and wheezing. Chest computed tomography scan revealed atelectasis in the right middle lobe. Fiberoptic bronchoscopy was performed. Results showed a calcified stone with filamentous fungi with septa in the right middle lobe bronchus, which was subsequently removed. Ceriporia lacerata was detected repeatedly on sputum culture. Thus, the filamentous fungi were suspected as C. lacerata. Broncholithiasis possibly caused mucous membrane damage owing to C. lacerata colonization, resulting in allergic airway inflammation. Herein, we report a rare case of C. lacerata-related broncholithiasis associated with asthma exacerbation.
