“…Otherwise, this condition appears to be asymptomatic, although the causative fungus can produce serious infections in immunocompromised patients. Cutaneous trichosporonosis and trichosporon onychomycosis have also been reported (82,138). Black piedra is similar to white piedra in that it is a nodular, generally asymptomatic fungal infection of the hair shafts.…”

Predispositions to the superficial mycoses include warmth and moisture, natural or iatrogenic immunosuppression, and perhaps some degree of inherited susceptibility. Some of these infections elicit a greater inflammatory response than others, and the noninflammatory ones are generally more chronic. The immune system is involved in the defense against these infections, and cell-mediated immunity appears to be particularly important. The mechanisms involved in generating immunologic reactions in the skin are complex, with epidermal Langerhans cells, other dendritic cells, lymphocytes, microvascular endothelial cells, and the keratinocytes themselves all participating in one way or another. A variety of defects in the immunologic response to the superficial mycoses have been described. In some cases the defect may be preexistent, whereas in others the infection itself may interfere with protective cell-mediated immune responses against the organisms. A number of different mechanisms may underlie these immunologic defects and lead to the development of chronic superficial fungal infection in individual patients. Although the immunologic defects appear to be involved in the chronicity of certain types of cutaneous fungal infections, treatment of these defects remains experimental at the present time.

“…In addition, Trichosporon species have emerged as infrequent but often fatal opportunistic pathogens in immunocompromised patients (12,22). Historically, Trichosporon infection has been known to occur as a white piedra in the hair in tropical and subtropical regions (8). Taxonomical investigations of the causative agents were conducted on the basis of new taxonomic criteria (1,5,19,20).…”

We determined the partial sequences of large subunit rDNA of a new yeast species, Trichosporon domesticum, which was isolated from the house of a summer-type hypersensitivity pneumonitis patient. Phylogenetically, T. domesticum was positioned in the taxonomic group containing T. montevideense and T. brassicae, which indicated an identical serotype. A phylogenetic relationship among all species of the genus Trichosporon which belong to the basidiomycetous yeast is clarified.

“…The species is widely distributed in the environment and has been recovered from normal skin and oral microflorae (31,32). Since disseminated infection caused by T. cutaneum was first reported by Watson and Kallichurum in 1970 (33), reports of this rare disease in immunocompromised patients have been increasing (4,11,12,18,29,32). The clinical picture of disseminated trichosporonosis consists of pneumonia, hepatitis, encephalitis, and septicemia (32).…”

Taxonomic position of deep-seated, mucosa-associated, and superficial isolates of Trichosporon cutaneum from trichosporonosis patients

et al. 1995

Clinical isolates of Trichosporon cutaneum, the causative agent of trichosporonosis, were identified on the basis of DNA relatedness. Of the 10 strains from deep-seated and mucosa-associated infections, 9 were identified as T. asahii and 1 was identified as T. ovoides. The two superficial strains were identified as T. cutaneum and a variety of T. montevideense. These findings suggest that T. cutaneum is a heterogeneous species in clinical samples and that the causative agents of trichosporonosis exist in four or more species.
