Tinea Cruris Treatment Tips

Tinea cruris is a common and important clinical problem that may, at times, be a diagnostic and therapeutic challenge.

Tinea cruris is the name used for infection of the groin with a dermatophyte fungus. An infection of the groin is usually caused by anthropophile fungi. The most common species are Epidermophyton floccosum and Tricophyton rubrum. It is most often seen in adult men. Opportunistic infections (infections that are caused by a diminished immune system) are frequent. Fungus from other parts of the body (commonly tinea pedis or 'athlete's foot') can contribute to jock itch. Tinea cruris has a worldwide distribution but is found more commonly in hot humid climates. Tinea cruris manifests as a symmetric erythematous rash in the groin.

Clothing that fits tightly is thought to be a predisposing factor in tinea cruris. A red rash then develops in the groin, usually with a definite edge or border. Both groins are commonly affected. The rash often spreads a short way down the inside of both thighs. Sometimes the infection spreads to the skin on other parts of the body (or may have first started in another area such as athlete's foot). Fungal infections do not usually go deeper than the skin into the body, and are not usually serious.Tinea cruris is best treated with antifungal drugs applied topically. Traditionally creams containing clotrimazole or miconazole have been used, although newer agents such as butenafine are also used. These anti-fungal agents work by stopping the fungi from producing a substance called ergosterol.
