title: [An autopsy case of Aspergillus pneumonia after inhalation of a great deal of dust in a mushroom factory].
abstract: A man in his forties with alcoholic liver injury was referred to our hospital because of progressive dyspnea and diffuse infiltrative shadows in both lung fields. Two weeks before admission he had carried a lot of rotten Enoki mushrooms in his factory, and then inhaled a great deal of airborne dust. Serological examination showed extremely elevated beta-D-glucan and positive Aspergillus antigen. Culture of dust collected from the floor of the factory proved to be positive for Aspergillus fumigatus. Aspergillus pneumonia was diagnosed and treatment with anti-fungal drugs was started. In spite of intensive treatment he died of respiratory failure. The autopsy disclosed multiple abscess formation containing hyphae of Aspergillus fumigatus and granulomatous reaction with multinuclear giant cells. However, there was no Aspergillus invasion in other organs. This was a rare case of invasive pulmonary aspergillosis that developed after inhalation of organic dust in a non-immunocompromised host.
