This case report describes Fournier's gangrene in a 35-year-old male following elective inguinal orchiectomy for testicular cancer. The aetiology was unknown, possibly beginning in the bottom of the scrotum following orchiectomy, alternatively through the scrotal skin after hair removal prior to surgery. Survivors from Fournier's gangrene often suffer from severe long-term morbidity, and multidisciplinary treatment is important for outcome optimization.
