Pulmonary blastomycosis diagnosed in Hawai'i.

Blastomycosis, a fungal infection caused by Blastomyces dermatitidis, was once thought to be endemic only to the Central and Great Lakes regions of the United States of America. We present the first reported case series of patients documenting the diagnosis of blastomycosis in the Pacific region. In both cases, exposure to endemic areas was retrospectively identified.
