Insidious Blastomycoses Osteomyelitis in a Young, Immunocompetent Male.

Blastomyces is a fungus that is endemic to the Ohio and Mississippi River Valleys and Great Lakes region. The fungus is a rare cause of infection, but most commonly causes infections of the lungs followed by the skin and bones. Infection of the bone is often not clinically suspected, which can slow the diagnosis. In this report, we present a case of Blastomyces osteomyelitis in a young, immunocompetent male.
