Synopsis

Tinea cruris (jock itch) is a superficial fungal infection of the skin of the groin area, most commonly caused by Trichophyton rubrum or other dermatophytes. Tinea cruris manifests as a symmetric or an asymmetric erythematous rash on the inner thighs and the crural folds. It rarely spreads to the penis, but if it does, it will be found only at the base of the penis. It is often spread to the groin from a fungal infection of the feet (tinea pedis).

Tinea cruris is frequently pruritic. It is more common in postpubertal males. 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.

Tinea cruris can be differentiated from cellulitis based on the location and the presence of scaling. In contrast to cellulitis, tinea cruris often occurs bilaterally.

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