Disseminated blastomycosis with cutaneous involvement in a 57-year-old woman: a case report and review of management


Blastomycosis is an infectious disease produced by the fungal organisms, Blastomyces dermatiditis and Blastomyces gilchristi. We present a 57-year-old woman with pulmonary blastomycosis and secondary cutaneous involvement. Her diagnosis was facilitated by dermatology consultation after approximately one year of delay. In endemic areas including Canada and the USA, individuals are at risk for blastomycosis when non-motile fungal spores are inhaled, thus producing pulmonary disease. The organism may disseminate over time, affecting a variety of extrapulmonary organ systems including the skin. In endemic regions of blastomycosis, this important cutaneous manifestation of disease should be considered with a high index of suspicion as to avoid delayed resolution and adverse outcomes.
