title: Chronic papular dermatitis of the scrotum due to Schistosoma mansoni.
abstract: A 17-year-old boy with chronic papules of the scrotum showed no improvement after topical therapy. A skin biopsy specimen showed Schistosoma mansoni eggs. No evidence of bladder or bowel involvement was found. No treatment is necessary for schistosomal infections without severe symptoms or excessive egg production.
