The anterior nares are commonly infected by Staphylococcus aureus (also known as "golden staph") which may contribute to dermatitic skin lesions in patients with atopic dermatitis.
Athlete's foot can usually be diagnosed by visual inspection of the skin, but if the diagnosis is uncertain, direct microscopy of a potassium hydroxide preparation of a skin scraping (known as a KOH test) can confirm the diagnosis of Athlete's foot and help rule out other possible causes, such as candidiasis, pitted keratolysis, erythrasma, contact dermatitis, eczema, or psoriasis.
