Pulmonary adiaspiromycosis in a patient with acquired immunodeficiency syndrome.

Adiaspiromycosis is a noninfectious, nonarthropod-transmitted fungal infection that occurs worldwide in lower vertebrates, especially rodents. However, humans may become accidental hosts. Reported here is a case of adiaspiromycosis of the lung in an HIV-positive, 40-year-old, bisexual man who first presented with cough and dyspnea. Cultures of a bronchoalveolar lavage and protected brush specimen revealed the presence of fungal elements that were identified as Emmonsia parva var. parva. The patient was successfully treated with amphotericin B and thereafter with fluconazole. This organism should be added to the list of pathogens that cause pulmonary infection in AIDS patients.
