A case of disseminated blastomycosis presenting as intramuscular abscess

Abstract

The syndrome of systemic blastomycosis is well described, and has a predilection for involving the lungs, skin, bone, and genitourinary tract. We report a unique case of disseminated disease in an immunocompetent male, in which the presenting symptoms included focal intramuscular involvement. In this case, it was the discovery of the intramuscular abscess that led to the diagnosis of systemic blastomycosis. We provide a general discussion of this endemic mycosis, with focus on disseminated disease and the rare complication of skeletal muscle abscess.
