Polypoid bronchial lesions due to Scedosporium apiospermum in a patient with Mycobacterium avium complex pulmonary disease.
A 69 yr old female was hospitalized for further examination of abnormal shadows on chest radiographs. She had a history of tuberculous pleurisy, rheumatoid arthritis and gold-induced interstitial pneumonia. On admission she still suffered from rheumatoid arthritis. A chest computed tomography scan on admission showed clusters of small nodules in subpleural regions of both lungs combined with bronchiectasis. Mycobacterium avium complex was cultured repeatedly from the sputum. Bronchoscopic examination disclosed white-yellow polypoid lesions in the orifice of the left B4 bronchus. Cultures of the brushing specimen of the polypoid lesions and bronchial aspirates from the B4 bronchus yielded smoky-grey mycelial colonies that were later identified as Scedosporium apiospermum. It was concluded that the polypoid bronchial lesions due to Scedosporium apiospermum were formed in the preexisting dilated bronchus caused by Mycobacterium avium complex pulmonary disease.
