Erythrasma is a chronic superficial infection of the intertriginous areas of the skin that causes brown, scaly skin patches. It presents as a slowly enlarging area of pink or brown dry skin. It occurs most often between the third and fourth toes, but it can also frequently be found in the groin, armpits, and under the breasts. Because of the color and location, it is often confused with a fungal infection like jock itch. Erythrasma is mainly treated with topical fusidic acid or topical erythromycin gel or clindamycin solution twice a day for 2 weeks.
