title: North American blastomycosis: the importance of a differential diagnosis.
abstract: Diseases from the major pathophysiological subgroups, including inflammatory, infectious, neoplastic, autoimmune, and metabolic disorders, can present in a very similar clinical manner. The importance of generating a broad differential diagnosis is supported by a case in which an 80-year-old white man presented with a verrucous plaque on the tip of his nose. The appropriate differential diagnosis for such a lesion as well as an overview of the disease diagnosed, North American blastomycosis, is presented.
