ABSTRACT

The case of a 60 year old woman with hemoptysis and a thin-walled cavitary lesion at the upper lobe of the right lung is presented. The woman presented at the Mycology Unit of the Muñiz Hospital in Buenos Aires City 3 months after the beginning of her clinical manifestations. A hyaline micelial fungus with chlamido-arthroconidias was isolated from the bronchoalveolar lavage. Immunodiffusion and counter-immnunoelectrophoresis with coccidioidin and histoplasmin rendered positive results against both antigents, and skin tests with coccidioidin and histoplasmin were also positive with strong reactions. The isolated fungus was identified as Coccidioides posadasii at the National Microbiology Institute Carlos Malbrán, by means of a molecular technique. The patient was treated with itraconazole by oral route at a daily dose of 200mg with good clinical response, but due to the persistence of the lung cavity, a surgical removal of the upper lobe of the right lung had to be scheduled (AU)
