Pulmonary adiaspiromycosis: The first reported case in Turkey

Abstract

Adiaspiromycosis is a world wide airborne infection and is a pulmonary disease in humans caused by the fungus Chrysosporium parvum var crescens (Emmonsia parva). It is caused by inhalation of spores of the saprophytic soil fungus. The spherules induce a granulomatous reaction, in which a single spherule is surrounded by a fibronecrotic and suppurative or fibrous granuloma. The disease can be localized and asymptomatic, or disseminated, occasionally severe, or even fatal. Reticulonodular infiltrates are the most common radiographic manifestations, with localized infiltrates occurring occasionally. We present a case with bilateral diffuse interstitial micronodular infiltration and granulomatous inflammation in the lung. The larvae of adiaspiromycosis visualized in the center of granulomatous inflammation by histopathologic examination of the lung biospy specimens. We aimed to discuss the very rare cause of diffuse interstitial and granulomatous inflammation of lung.
