    Oral Antifungal Drugs in the Treatment of Dermatomycosis.
    Med Mycol J 2016 ;57(2):J71-5
    Department of Dermatology, Tokyo Women's Medical University.
    Oral antifungal drugs are used primarily to treat tinea unguium; however, they are also useful for other types of tinea. For example, a combination of topical and oral antifungal drugs is effective in hyperkeratotic tinea pedis that is unresponsive to topical monotherapy. In cases of tinea facialis adjacent to the eyes, ears, or mouth, or widespread tinea corporis, or tinea cruris involving the complex skin folds of the external genitalia, it is difficult to apply topical drugs to all the lesions; therefore, oral antifungal drugs are necessary.
