Athlete’s foot, technically known as tinea pedis, is a skin infection of the feet caused by a fungal infection. This type of organism grows best in warm, moist places and sometimes worsens during the summer. It is more common in adults but can occur in children. The patient develops an itchy, scaly rash on the soles of the feet and sometimes between the toes. Treatment includes topical or systemic antifungal medications. It is also important to keep the feet dry.
