Paecilomyces species are among the most frequent saprophytes. Two species namely Paecilomyces lilacinus and Paecilomyces variotii are the most frequently isolated species from humans. Fungemia, endocarditis peritonitis, osteomyelitis and rarely pneumonia have been reported. We report a 74-year old diabetic woman with Paecilomyces variotii pneumonia. Paecilomyces variotii is a rare cause of pneumonia and in our knowledge, our case is the first case of pleural effusion due to this fungus.
