title: Penicillium marneffei in bronchoalveolar lavage fluid.
abstract: Penicillium marneffei is a rare human pathogen that may infect either healthy or immunocompromised hosts. In methenamine silver-stained preparations of bronchoalveolar lavage fluid from a patient with dermatomyositis on steroid treatment, round-to-oval intracellular and extracellular microorganisms were found. The finding of occasional septate and elongated forms established the microorganism as probably P marneffei, which was confirmed on culture. Distinguishing this rare fungus from Pneumocystis carinii is important because these two diseases require different forms of treatment.
