Tinea cruris

The superficial mycotic infections occur on the surface of, or just below, the skin or nails. Superficial infections include tinea pedis (athlete s foot), tinea cruris (jock itch), tinea corporis (ringworm), onychomycosis (nail fungus), and yeast infections, such as those caused by Candida albicans. Yeast infections or those caused by C. albicans affect women in the vulvovaginal area and can be difficult to control. Women who are at increased risk for vulvovaginal yeast infections are those who have diabetes, are pregnant, or are taking oral contraceptives, antibiotics, or corticosteroids.

Tinea infections are superficial fungal infections in which the pathogen remains within the keratinous layers of the skin or nails. Typically these infections are named for the affected body part, such as tinea pedis (feet), tinea cruris (groin), and tinea corporis (body). Tinea infections are commonly referred to as ringworm due to the characteristic circular lesions. In actuality, tinea lesions can vary from rings to scales and single or multiple lesions. 

Tinea infections are second only to acne in frequency of reported skin disease.35 The common tinea infections are tinea pedis, tinea corporis, and tinea cruris. Tinea pedis, the most prevalent cutaneous fungal infection, afflicts more than 25 million people annually in the United States.
