Trichosporiasis

Trichosporonsis is a superficial and systemic infection caused by Trichosporon. More common in tropical regions. Some temperate regions, especially the southeastern United States, also have higher rates. White hair nodules are more common in young men, especially around the genitals. But it does not appear to be contagious, and poor personal hygiene and low socioeconomic status are not risk factors for the disease. Phylogeny is similar to Cryptococcus. In fact, including a heterogeneous group, most Trichosporon can assimilate most carbon and nitrogen sources, making it difficult to identify traditional nutrition experiments. Superficial infections, also known as white hair nodules, are white, brown-black, or green granular spindle-shaped nodules that surround the hair shaft and are scattered randomly. Sometimes nodules can fuse into clumps. Some patients with hereditary qualities can react with antigens from Trichosporum and cause pneumonia. The clinical manifestations are superficial infection, allergic pneumonia, and invasive trichosporia. Tissue culture, blood culture, and skin tissue pathology are very useful for diagnosis.
