Subcutaneous phaeohyphomycosis caused by Exophiala spinifera.

The second human subcutaneous infection due to Exophiala spinifera from the United States is described. Identification was based on the morphology of the fungus in tissue and the morphological features of the culture obtained from the biopsy material. Correct diagnosis and treatment with ketoconazole and 5-fluorocytosine cured the infection.
