Successful treatment of systemic and local infections due to Exophiala species.
We report the successful treatment of three cases of infection due to Exophiala species. These organisms belong to the heterogeneous group of dematiaceous (darkly pigmented) fungi. Two cases of infection occurred in organ transplant recipients who were receiving immunosuppressive medications. Both of these infections remained localized to the subcutaneous tissues and were successfully treated with surgical excision of the lesions. We also describe what is to our knowledge the first reported case of prosthetic valve endocarditis due to Exophiala castellanii that was managed with a combination of medical and surgical therapies. Exophiala species remain an uncommon cause of infection. However, as the population of immunocompromised patients continues to grow and further improvements in the microbiological techniques for identification of these fungi occur, these organisms will be recognized with increasing frequency as a cause of human disease.
