A previously healthy 16-year-old male was admitted to the hospital with severe scrotal and penile swelling. The onset of the problem was 6 days earlier, beginning with only some pruritus. However, the next day, he noticed progressive swelling, and he informed his mother, who felt like it was nothing unusual and continued to watch. Two days later, however, the swelling and itching were significantly worse and he was taken to the ED. There, a fungal infection was diagnosed (“jock itch”) and he was given a prescription for fluconazole, along with topical antifungal cream. However, the next day, the swelling had reached a massive size and he returned to the ED, where an ultrasound of the scrotum was performed, ruling out testicular torsion or other intrascrotal abnormality, and he was diagnosed with cellulitis. He was given IV clindamycin plus nafcillin and referred for admission.
