The diagnosis is established by a positive potassium hydroxide (KOH) examination. A KOH preparation will demonstrate branching hyphae ( Fig 239:4). If a KOH

examination is negative, one of the other above-mentioned disorders should be considered. Treatment

Antifungal creams such as clotrimazole (Lotrimin or Mycelex), ketoconazole (Nizoral), or econazole (Spectazole) twice a day is the initial treatment. Clotrimazole is suggested initially as it is of low cost and is nonprescription. Spectazole also has antibacterial properties and is preferred if maceration is present. Treatment also includes keeping the affected area as cool and dry as possible. Wearing loose-fitting clothing is recommended. Antifungal powders such as Zeasorb AF should be used on a daily basis to prevent recurrences.
