Superficial fungal infections are common. Most diagnoses of fungal infections of 
the skin can be made by physical examination, assisted by the use of a Wood's 
lamp, skin scrapings for microscopic examination, and fungal cultures. 
Dermatophyte infections are common at all ages, in both sexes, and they have a 
worldwide distribution. These infections include tinea capitis, tinea cruris, 
tinea pedis, tinea corporis, tinea manuum and tinea barbae. Tinea versicolor, 
caused by Malassezia furfur, and candidal infections are also common. Treatment 
modalities include oral and topical agents. Good personal hygiene is an 
important adjunct to antifungal therapy. Decisions regarding the appropriateness 
of therapy in a given patient must take into account the extent and location of 
the infection, the benefits and risks of each of the treatments, and cost. Oral 
therapies include griseofulvin, ketoconazole, and itraconazole. There are a 
large variety of topical treatments, including nystatin, selenium sulfide, 
tolnaftate, haloprogin, miconazole, clotrimazole, and sodium thiosulfate. 
Important to successful treatment is compliance with what is sometimes a long 
course of treatment, and good personal hygiene.
