Direct examination of a bronchial lavage sample revealed organisms morphologically consistent with Blastomyces dermatitidis, which was confirmed by culture. The patient was placed on intravenous antifungal therapy and his condition improved dramatically.OBJECTIVES: to describe the gross and microscopic morphologies of both yeast and mold forms of B. dermatitidis; to identify B. dermatitidis given patient history, and microscopic and colony morphology; to describe the symptoms of primary pulmonary infections caused by B. dermatitidis, and to name additional tissues typically affected by the systemic pathogen.ABBREVIATIONS: AIDS = acquired immunodeficiency syndrome; ANA = antinuclear antibodies; HSV = herpes simplex virus; KOH = potassium hydroxide; RBC = red blood cell; WBC = white blood cell.
