Chronic Scaly Athlete’s foot (moccasin type)

There are three defined types of athlete’s foot. Moccasin-type athlete’s foot infection can be very difficult to treat and the condition can last for a long time. It is caused by a genus of ringworm, Trichophyton rubrum, and must be treated with prescription medications.

Moccasin-type often begins with a minor irritation. The skin can be dry, itch, burn and/or become scaly. The scale is typically fine and silver in color. The skin underneath can be pink and tender to the touch. As it progresses, the skin thickens and the skin on the sole or heel begins to crack. As it progresses, the toenails can become involved, thickening and crumbling. It is also possible for the infection to develop on the palm of the hand. Typically, both feet and one hand, or both hands and one foot, are infected.

Moccasin-type infection is hard to treat because the sole of the foot is thick and does not respond well to nonprescriptions antifungals. Treatment often involves using a prescription antifungal cream that will penetrate into the sole of the foot. Sometimes, prescription oral antifungal medications are also used.

Once moccasin-type athlete’s foot is healed, it is very important to take preventive measures as re-infection is not uncommon.
