Tinea cruris, also known as jock itch, is a type of fungal infection of the skin of the groin region.[3][6] Symptoms typically include an itchy, red, and raised rash with a scaly and well-defined curved border.[1][5] Most commonly this occurs over the upper inner thighs.[5]

It is cause by a group of fungi known as dermatophytes.[6] Risk factors include excessive sweating, tight fighting clothing, contact sports, diabetes, and poverty.[6] It may spread to the groin from athletes foot, a fungal nail infection, or an infected towel or other clothing.[1][5] Diagnosis may be confirmed by microscopy or culturing of skin scrapings.[4] Similar conditions include candidal intertrigo, erythrasma, inverse psoriasis and seborrhoeic dermatitis.[4] It is a type of dermatophytosis.[6]

Treatment is typically with antifungal creams which are particularly effective if started soon after symptoms onset.[1] In more significant cases antifungals, such as terbinafine, by mouth may be used.[1] Steroid cream may speed symptom improvement.[4] Prevention of recurrences include treating other fungal infections and taking measures to avoid moisture build-up by keeping the groin dry, avoiding tight clothing, and losing weight if obese.[7]

Tinea cruris is common.[5] Males are affected more often than females and it occurs more commonly in hot-humid climates.[6] Children; however, are rarely affected.[5] Tinea was first described in 30 AD by Aulus Cornelius Celsus.[8]
