Abstract
|

|
|
We report a case of pulmonary fungal ball of Pseudallescheria boydii (Scedosporium apiospermum, the anamorph) and the result of LSU rDNA D2 region sequencing of the clinical isolate. An immunocompetent 58-year-old female suffered 2-year history of hemoptysis. Her symptom persisted despite the administration of oral itraconazole, even though the clinical, radiological, and histological findings suggested Aspergilloma. In the fungal culture, the typical morphology of S. apiospermum was observed. Even though the sequencing using LSU rDNA D2 region identified the organism as Pseudallescheria ellipsoidea, one of the P. boydii complex, the further investigation of ours suggested that the species in P. boydii complex could not be differentiated from each other by the sequencing of LSU rDNA D2 region.
