Classification and pathogenesis of vulvovaginal candidiasis.

Although candidiasis of the female genital tract is one of the most common of the vaginitides, it is a poorly understood disease entity. Vulvovaginal candidiasis is a monoetiologic disease, but the pathways by which pathogenic expression is attained are sufficiently divergent to constitute a classification schema that influences therapy. For selection of appropriate therapy, the following three broad categories are proposed: (1) primary candidiasis, (2) antibiotic-induced candidiasis, and (3) systemically induced candidiasis.
