• Resumen

  • Blastomycosis is an endemic fungal infection due to Blastomyces dermatitidis that most commonly causes pneumonia; but the organism can disseminate to any organ system, most commonly the skin, bones/joints, and genitourinary tract. Both immunocompetent and immunocompromised persons can be infected, but more severe disease occurs in the immunocompromised. Blastomycosis can be diagnosed by culture, direct visualization of the yeast in affected tissue, and/or antigen testing. Treatment course and duration depend on severity of illness. For mild to moderate pulmonary disease the treatment is itraconazole. For severe blastomycosis, lipid formulation amphotericin B is given, followed by step-down therapy with itraconazole.
