Disseminated Trichosporon capitatum infection in an immunosuppressed host.

Trichosporon is a frequent cause of superficial mycotic infections but has rarely been associated with invasive disease. A patient undergoing bone marrow transplantation who died from disseminated Trichosporon capitatum infection with endocarditis is reported, and the clinical spectrum of human infection caused by fungi of this genus is reviewed. To our knowledge, this is the first reported case of clearly invasive disease caused by this specific organism and emphasizes the expanding spectrum of unusual infections in the severely immunosuppressed patient.
