A fungal infection of the perineum (the region between the thighs), better known as jock itch.

This condition is often treated with clotrimazole (antifungal drug) or miconazole cream (antifungal agent). Good general hygiene is vital in the prevention of tinea cruris.

Keep the groin area clean and dry and avoid chafing. Launder athletic supporters frequently. Use an antifungal, or drying powder, after taking a shower.
