Phaeohyphomycosis from Exphiala jeanselmei with concomitant Nocardia asteroides infection in a renal transplant recipient: case report and review of the literature.

ABSTRACT

A 59-year-old black man who received a cadaveric renal transplant 15 months earlier developed subcutaneous nodules on his right upper extremity that were identified as phaeohyphomycosis caused by Exophiala jeanselmei. The man was admitted 4 weeks later with a swollen left arm and had Nocardia asteroides in this area and in the apex of his left lung. He was treated with surgical excision, and itraconazole, imipenem-cilastatin, and trimethoprim-sulfamethoxazole. With the potential presence of more than one microorganism in an immunocompromised patient, it is important to identify and differentiate them correctly to direct appropriate therapy.
