Chilblain is an infection caused by the fungi Trichophyton mentagrophytes or Trichophyton rubrum, which attacks preferentially the soles of the feet and the spaces between the fingers. Also known as tinea pedis or athlete's foot, chilblain is the most common mycosis of skin in the world.
Ringworm in the groin, called in medicine of tinea cruris, is one of the most common fungal infections of the skin. Tinea cruris usually reach the inguinal (groin), thigh and buttock regions, causing red plaques and intense itching.
