Cutaneous blastomycosis in New Brunswick: case report.

Blastomycosis is a fungal infection of immunocompetent hosts. We present a case of cutaneous blastomycosis acquired in New Brunswick, which provides evidence that this disease is endemic in Atlantic Canada. This case also demonstrates that the diagnosis of blastomycosis may be elusive. Perseverance, a high index of clinical suspicion and close cooperation with the microbiology laboratory may be required to diagnose this uncommon condition.
