Tinea Cruris

Tinea cruris, also known as crotch itch, crotch rot, Dhobie itch, eczema marginatum, gym itch, jock itch, jock rot, and ringworm of the groin is a dermatophyte fungal infection of the groin region in any sex, though more often seen in males. In the German Sprachraum this condition is called Tinea inguinalis (from Latin inguen = groin) whereas Tinea cruris is used for a dermatophytosis of the lower leg (Latin crus).

Tinea Cruris is similar to, but different from Candidal intertrigo, which is an infection of the skin by Candida albicans. It is more specifically located between intertriginous folds of adjacent skin, which can be present in the groin or scrotum, and be indistinguishable from fungal infections caused by Tinia. However, candidal infections tend to both appear and disappear with treatment more quickly. It is also worth noting that tinea cruris generally does not infect the scrotum.
