A Case of Cutaneous Abscess Due to Scedosporium apiospermum / 대한피부과학회지

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.

A Case of Melanonychia Caused by Trichophyton rubrum / 대한피부과학회지

We report a case of fungal melanonychia caused by Trichophyton (T.) rubrum in a 69-year-old female patient. She had brownish to black pigmentation affecting all toe nails that clinically simulated melanonychia. Mycologic examination of toe nails revealed T. rubrum. The causes of melanonychia are numerous, but fungal origin is rare. Although T. rubrum is known to be one of the frequently isolated organisms of fungal melanonychia, there have been no reports of T. rubrum-induced melanonychia yet in Korea.
