Ringworm - Superficial fungal infection of the feet is somewhat unique because of the location. Between the toes (most commonly the fourth and fifth), the condition appears as erythema, maceration, and scaling. In some cases, this may become secondarily infected. It is attended by itching or vague discomfort. On the sole and the lateral aspects of the feet, scattered pustules and vesicles with surrounding erythema and edema may occur. More commonly, there is persistent dry scale in a “moccasin” distribution with minimal inflammation.
