A two-month-old, previously healthy Hispanic boy was transferred from a local hospital. He had a 2-week history of increased redness of his scrotum and penis. Two days prior to admission, the patient's mother noticed an ulcerative lesion on his scrotum. She had been treating the lesion with clotrimazole cream but took him to the local hospital when the lesion did not improve. Prior to transfer to our hospital, he was started on ceftriaxone sodium and vancomycin hydrochloride owing to the presumed infectious nature of the lesion. There was no associated fever, lethargy, or bleeding from the lesion, but significant pain was noted with diaper changes.
