Histopathological evidence of North American blastomycosis in Italy: report of two cases

No clinical reports of blastomycosis in Italy have been published until now. We here report two cases of histologically diagnosed, unexpected cutaneous involvement in patients, aged 78 and 52 years, living in North Italy and never having been abroad. The histological differential diagnosis between blastomycosis and other fungal pathogens is discussed. Even in the absence of culture the present cases can confidently be considered as genuine examples of Blastomyces dermatitidis infection in Italy.
