Synopsis

Tinea cruris (jock itch) is a superficial fungal infection of the skin of the groin area, most commonly caused by Trichophyton rubrum. Tinea cruris manifests as a symmetric or an asymmetric erythematous rash on the inner thighs and the crural folds. It is often spread to the groin from a fungal infection of the feet (tinea pedis).

Tinea cruris is frequently pruritic. It occurs most frequently in men but may also affect postpubertal females. People at higher risk include those who have diabetes mellitus, are obese, recently visited a tropical climate, wear tight-fitting or wet clothes (including bathing suits) for extended periods, share clothing with others, or participate in sports.

In the immunocompromised patient, pruritus may be absent. There is an increased risk of all dermatophyte infections (tinea pedis, cruris, corporis, and faciei as well as Majocchi granuloma) in immunocompromised individuals.

A severe antifungal-resistant tinea has emerged in South Asia from the rapid spread of a novel dermatophyte species: Trichophyton indotineae. Terbinafine-resistant T indotineae infections have been reported in Asia, Europe, Canada, and the United States, including one case in New York City with no history of recent international travel.
