“…Dissemination was reported to occur in up to two-thirds of patients, in earlier reports [16,31]; however, the rate that we found (30.1% of patients) is consistent with recently reported dissemination rates of ∼25% [12,29,30]. As awareness of blastomycosis increases and diagnosis is made earlier in the course of disease, it is possible that extrapulmonary disease is being observed with less frequency.…”

“…The proportion of men among the patients in our study (65.0%) is similar to the proportions reported in recent studies from other areas of endemicity, which show a more equal distribution between the sexes [12,17,29,30] than was previously reported [16,20,31]. Similarly, an outdoor occupation was noted for only 13% of case patients in our study; in an earlier report of cases diagnosed in Manitoba, some form of outdoor occupation or activity was indicated for 60% of patients [16].…”

“…Earlier studies reported that male sex and employment in outdoor occupations were associated with blastomycosis [16,20,31].

Blastomyces dermatitidis is a dimorphic fungus endemic to Canada and the United States. Few reports regarding blastomycosis in Canada have been published. We retrospectively reviewed the medical charts of 143 patients with confirmed cases of blastomycosis diagnosed in hospitals in Manitoba, Canada, from 1988 through 1999. The annual incidence rate of blastomycosis in Manitoba was 0.62 cases per 100,000 population, compared with 7.11 cases per 100,000 population in the Kenora, Ontario district. The average age of patients was 38.0 years, and males accounted for 65.0% of cases. An increased incidence of blastomycosis was observed in the Aboriginal subpopulation. Organ systems involved were as follows: respiratory system (93.0% of cases), skin (21.0%), bone (13.3%), genitourinary tract (1.4%), and the central nervous system (1.4%); 6.3% of patients died, and death was associated with a short clinical course. This study provides a summary of the current status of blastomycosis in this area of endemicity in Canada.

“…Our patient had not resided in a classically considered 'blastomycosis endemic area' 3 ; however, the patient did admit to gardening occasionally at these locations, which could have possibly explained her exposure to this fungus. 3 To our knowledge, no autochthonous cases have been reported from Mexico.…”

Cutaneous lesions in patients with systemic lupus erythematosus (SLE) represent diagnostic challenges. Opportunistic infections should be considered when lupus patients are on immunosuppressive therapy and other causes, such as disease activity, are less likely to explain the skin lesions. Within the spectrum of skin opportunistic infections that might occur in SLE patients, Blastomyces dermatitidis should be suspected when acid-fast positive material with no bacilliform organisms is seen on Ziehl-Nielsen skin biopsy preparations. In this study, we describe one patient with SLE on immunosuppressive therapy, who developed cutaneous blastomycosis despite living in a non-endemic area. Because of lack of awareness about this association and misinterpretation of the skin biopsy results, the diagnosis of atypical mycobacterial infection was initially considered. Subsequent proper tissue staining and interpretation revealed the correct diagnosis of disseminated cutaneous blastomycosis. This description represents the first report of this rare opportunistic skin infection in SLE, illustrating the importance of performing correct preparation and elucidation of the skin biopsy to avoid misdiagnosis and treatment delay.

“…2 Blastomycosis was originally thought to be geographically localized to North America. 3 However the term North American blastomycosis is misleading as Blastomyces dermatitidis has a worldwide distribution and has been documented in at least 15 African countries as well as in Europe, South America, the Middle East and South Asia. 4 Blastomycosis is caused by thermally dimorphic microfungus, Blastomyces dermatitidis, grows as a nonpathogenic mold in soil and its conida convert to pathogenic yeast in the host 4 .…”

Cutaneous blastomycosis lesion is most often originate from a Primary pulmonary infection which disseminates through the blood or lymphatics to involve the skin. During the manifestations of cutaneous lesion in case of secondary blastomycosis, the primary pulmonary infection is frequently subclinical. Here we report a case that illustrates the difficulty in diagnosing a case of cutaneous blastomycosis.
