Dave Harvester is a 41-year-old man who presents to a family medicine clinic because of recent itching on his feet. He is an assistant manager at a local retail store who plays basketball at the YMCA for exercise three times a week. He sweats profusely during games and always showers before going home. He has not changed laundry detergent recently, but he admits that he does not always wash his athletic clothes between workouts. He says his feet have always smelled bad, but he first started to notice the burning and itching about 6 weeks ago. He started applying some deodorizing spray to his feet a week ago, but thus far it has only made a slight improvement in itching. Now his groin is starting to itch as well.
