A 31-year-old man presents to a homeless clinic complaining of a papular rash located on the occipital region of his scalp. The rash began several years earlier but improved without the use of any particular treatment. He noticed a return of similar lesions several weeks ago. He says that the lesions are increasing in number and are mildly pruritic. He has had exposure to a variety of new shampoos and laundry detergents since arriving at the homeless shelter. He denies fever, chills, or drainage from the lesions. He has not tried anything to resolve the lesions prior to being seen at the clinic. His main reason for seeking care was due to the cosmetic appearance of the lesions.
