Subcutaneous phaeohypomycosis caused by Scytalidium dimidiatum in the foot of an immunosuppressed host.

The authors present a case report of a subcutaneous phaeohypomycosis of the foot in an immuno-suppressed patient. The lesion was caused by Scytalidium dimidiatum, a dematiaceous fungus, which has only been reported to cause three previous similar lesions.
