Abstract
It has become clear that blastomycosis is very similar to histoplasmosis and coccidioidomycosis with respect to the epidemiology and immunology of the infection. As late as 1945, histoplasmosis was considered to be a uniformly fatal infection with less than 75 disseminated cases reported.1 With the advent of histoplasmin skin testing, it became clear that many persons without a clinical history had, indeed, been infected with the fungus.2 Similar findings are being discovered with blastomycosis. Patients with acute infection who recovered despite no therapy with an antifungal agent have been reported. The majority of those cases have been associated with point-source epidemics such as those at Big Fork, Minnesota, and Eagle River, Wisconsin.3,4 In that latter epidemic of blastomycosis, only 9 patients with culture-proven infection were treated with an antifungal agent.5 The other 35 patients with immunologic evidence of infection were not treated; none have had relapse of infection. Edson and Keys reported a number of patients who had no deleterious effects with only observation following surgical resection of a solitary pulmonary nodule as long as no other disease was present.5
