Abstract:
Allergic bronchopulmonary mycosis (ABPM) is a chronic respiratory disease in which saprophytic fungi grow in the airways of adults and induce types I and III allergic reactions. ABPM is often caused by Aspergillus spp.; however, data on non-Aspergillus ABPM are limited. The newly proposed diagnostic criteria for ABPM in Japan allow for the diagnosis without asthma or with non-Aspergillus ABPM. Nigroporus vinosus is a filamentous fungus present in mushrooms. We herein present the first case of ABPM caused by Nigroporus vinosus. The organism was identified in the sputum of a patient with clinically suspected ABPM, and the symptoms improved with corticosteroid treatment.
