Saccharomyces is an ascospore-producing yeast that is commonly employed in the brewery and bakery industries. We report a case of opportunistic skin infection with Saccharomyces in a 62-year-old female whose defense was impaired by immunosuppression. Previously reported cases have been treated with amphotericin B or ketoconazole and our patient respbnded to fluconazole. (Ann Dermatol 9:(1)41-45, 1997).
