Infection of the skin and toenails.

It is caused by a fungus. It affects moist areas of the skin.

It manifests as reddening, flaking and itching of the skin which is sometimes preceded by the apparition of wet blisters. In many cases, the skin lesion grows in a circle, adopting a characteristic ring shape.

It is diagnosed by examining the affected area.

Treatment is based on the administration of topical antifungal agents and keeping the extremities dry.
