Tinea cruris, most commonly known as jock itch, is a fungal infection of the skin.
Jock itch (Tinea Cruris) is a common fungal (caused by a fungus) infection similar to ringworm. that causes a red and itchy rash in warm and moist areas of the body. May be shaped like a ring and an itchy, stinging, burning rash on the skin around your groin, inner thighs and butt crack (gluteal cleft).
Jock itch gets its name because it’s common in athletes. It’s also common in people who sweat a lot or who are overweight. Although often uncomfortable and bothersome, jock itch usually isn’t serious. Treatment may involve keeping the groin area clean and dry and applying topical antifungal medications to the affected skin.
Jock itch (tinea cruris) is caused by a dermatophyte fungus, most commonly Trichophyton rubrum and Epidermophyton floccosum.
Spread of the infection to the groin is commonly from the feet (tinea pedis) or nails (tinea unguium) by scratching or use of contaminated towels or bed sheets.
Jock itch commonly spreads through skin-to-skin contact or contact with an infected surface. You can get jock itch through sexual contact with an infected person. You can also get jock itch by sharing towels or clothing with an infected person.
In some cases, you can get jock itch if you have athlete’s foot (tinea pedis). You can spread the fungus by touching your groin after touching your infected foot. You can also spread the fungus from your feet to your groin through your clothing.

In some cases, your doctor may take some scrapings of skin cells from the area to help diagnose the condition. This may also help rule out other skin disorders, such as psoriasis.
