A 46-year-old male presents to the office complaining of a pruritic skin rash that has been present for a few weeks. He initially noted the rash on his feet, but it then spread to between the fingers, his wrist, and waist. He notes that it does not seem to be on his face or trunk. He recently came home from a trip to Florida where he had stayed in multiple hotels. He takes occasional ibuprofen for knee pain, but denies taking other medications or having other health problems. He has no known drug allergies. The physical examination reveals a male with several tiny vesicles and scales in between the fingers, on the feet and ankles, around the patient's wrist and around the belt line.
