These fungi infest only dead tissues of the skin or structures that grow from the skin such as hair or nails.
Ringworm lesions are red, scaly and round.
The name ringworm comes from the appearance of the lesions as they begin to heal. These lesions heal from the inside out and leave a red rim. Without treatment, the lesions become larger at their borders and can linger. Sometimes redness is the only symptom while in other cases blisters may appear. The most obvious and bothersome symptom of this disease is the severe itchiness.
