%X <B>BACKGROUND: </B>Pulmonary adiaspiromycosis is a common disease of many species of wild rodents and occasionally of humans, caused by the inhalation of spores of the fungus Chrysosporium parvum var crescens (Emmonsia crescens).<BR><B>METHODS: </B>A 74-year-old female with pulmonary adiaspiromycosis was diagnosed by radiologically guided lung fine needle aspiration (FNA). The specimen showed intracellular and extracellular 100-300 microm conidia with a distinct thick, trilaminar wall, which was positive for Gomori-methenamine silver and periodic acid-Schiff stain. The background consisted of a granulomatous process.<BR><B>CONCLUSIONS: </B>FNA is an effective method of diagnosing pulmonary adiaspiromycosis, and pathologists need to be aware of the characteristic features of this unusual opportunistic fungal infection.
