Scedosporium apiospermum is the asexual stage of Pseudallescheria boydii that is ubiquitous in nature. The localized cutaneous abscess due to S. apiospermum is rare and it is usually originated from the traumatic inoculation of fungal elements. We report a case of cutaneous abscess caused by S. apiospermum. A 67-year-old woman presented with one-year history of subcutaneous nodules on the left forearm, which had been misdiagnosed as cutaneous tuberculosis. Cultural isolation for definitive diagnosis showed typical S. apiospermum. (Korean J Dermatol 2001;39 (7) 812-915)
