Tinea cruris

Tinea cruris, also known as crotch itch, crotch rot, Dhobi itch, eczema marginatum,gym itch,jock itch, jock rot, scrot rot and ringworm of the groin is a dermatophyte fungal infection of the groin region in any sex, though more often seen in males.

Tinea cruris is similar to, but different from Candidal intertrigo, which is an infection of the skin by Candida albicans.
