en Medical Mycology and Biotechnology Medical Mycology and Biotechnology case report case report Paecilomyces sp, is a saprophytic fungus which has rarely been associated with human disease. We report the first case of invasive subcutaneous infection caused by this fungus in a 78-year-old female from Damghan, Iran, with diabetes and chronic renal failure. A biopsy provided an initial diagnosis of the mold in tissue. Multiple positive fungal cultures which were obtained from the biopsied tissue were subsequently identified by microscopic and macroscopic characteristics to be Paecilomyces sp. This case was successfully treated by oral ketoconazole (200 mg/day).
