Tinea cruris, a pruritic superficial fungal infection of the groin and adjacent skin, is the second most common clinical presentation for dermatophytosis. Tinea cruris is a common and important clinical problem that may, at times, be a diagnostic and therapeutic challenge.
Jock itch (tinea cruris) is a fungal infection that affects the skin of your genitals, inner thighs and buttocks. Jock itch causes an itchy, red, often ring-shaped rash in these warm, moist areas of your body.
Jock itch gets its name because it is common in people who sweat a lot, as do athletes. It also is more likely to occur in people who are overweight.
Although often uncomfortable and bothersome, jock itch usually isn't serious. Keeping your groin area clean and dry and applying topical antifungal medications usually are sufficient to treat jock itch.
For a mild case of jock itch, your doctor may suggest first using an over-the-counter antifungal ointment, lotion, powder or spray. The rash may clear up quickly with these treatments, but continue applying the medication as directed for one to two weeks.
If you also have athlete's foot, treat it at the same time you are treating your jock itch. This will reduce the risk of recurrence. If jock itch is severe or doesn't respond to over-the-counter medicine, you may need prescription-strength creams or ointments — or even antifungal pills.
