Abstract



Scedosporium apiospermum is an asexual state of Pseudallescheria boydii which has been isolated from soil, sewage, and decaying vegetation. It can cause cutaneous infections by traumatic implantation of the contaminant due to penetrating injury. This ubiquitous fungus cause not only mycetoma, but also infections of variety of body sites including the skin. The localized skin infection due to this organism is much rare than mycetoma. We report a case of cutaneous S. apiospermum infection occurred in 80-year-old male. The skin lesion was manifested by a 8.0 × 4.0 cm-sized erythematous plaque with pustules and crusts on the dorsum of right hand. The fungal culture from the biopsy specimen on Sabouraud's dextrose agar showed white to gray colored cottony colonies of S. apiospermum. The nucleotide sequence of internal transcribed spacer for clinical isolate was identical to that of S. apiospermum strain IHEM 23829. The patient was treated with oral fluconazole for 3 months.
