Ringworm of the body (tinea corporis)

Ringworm of the body (tinea corpus) is a fungal infection that appears as itchy, red, scaly, slightly raised, expanding rings on the body. The ring grows outward as the infection spreads, and the center area becomes less actively infected.

Ringworm is contagious and spreads several ways, including skin-to-skin contact or contact with a contaminated object such as unwashed clothing. Treatment usually requires an antifungal prescription medication.

A tinea infection in the groin is called jock itch (tinea cruris), and a tinea infection of the foot is called athlete's foot (tinea pedis).
