| Abstract |
Allergic bronchopulmonary mycosis (ABPM) is a chronic immune-mediated pulmonary disease, which is caused by fungal infection of the airways. Aspergillus species are the main causative fungi and standard treatment typically comprises systemic corticosteroid therapy with or without adjunct antifungal agents. We describe our experience with a case of ABPM caused by Schizophyllum commune (S. commune), with satisfactory response to treatment with a combination of an inhaled corticosteroid and a long-acting β 2-agonist. The patient was a 61-year-old man who was referred to our hospital with dry cough and abnormal findings on chest radiography. He had peripheral blood eosinophilia and elevated levels of total serum IgE. High-resolution CT showed multiple areas of patchy consolidation with high-attenuation mucus plugs in the right upper lobe. Bronchoscopy revealed mucus plug impaction in the bronchial lumen, and Grocott's staining of the mucus detected fungal hyphae. Bronchioalveolar lavage fluid culture yielded white woolly colonies, which was subsequently identified as S. commune by MALDI-TOF MS and gene sequencing. Serology was positive for S. commune-specific IgE and IgG. We made a definitive diagnosis of ABPM caused by S. commune. Symptoms and chest CT findings improved considerably with inhaled combined fluticasone furoate/vilanterol trifenatate therapy, without the use of systemic corticosteroids or antifungal agents.
