A rare infection caused by the yeast-like fungus Blastomyces dermatitidis, which resides in dead wood and soil.
Blastomycosis is a rare fungal infection.
The lesion usually begins at the site of a skin injury such as a cut, bruise, or scrape. The initial lesion spreads locally on the surface of the skin, leaving behind a central scar. It may persist for long periods, mimicking skin cancer in appearance. Immunocompromised people such as those with AIDS are at increased risk for disseminated blastomycosis. There are no specific preventive measures for blastomycosis .
