Overview
Jock itch, medically known as Tinea Cruris, is a common fungal infection that affects the skin of the groin, inner thighs, and buttocks. In South Korea, it frequently occurs in athletes, men who sweat excessively, or individuals with warm, humid conditions. Dermatology clinics across the country, including Seoul National University Hospital, Samsung Medical Center, and Asan Medical Center, provide effective diagnosis and treatment using topical and systemic antifungal therapies.
What is Jock Itch?
Jock itch is a superficial fungal infection caused by dermatophytes, commonly Trichophyton species. It leads to itchy, red, and sometimes scaly skin lesions. Although it primarily affects men, women can also develop the condition. Jock itch is contagious and can spread through direct skin contact, contaminated clothing, or towels.
