title: Neonatal urethral polyps associated with Beckwith-Wiedemann syndrome.
abstract: We report the first case of Beckwith-Wiedemann syndrome without urinary obstruction, but with a congenital urethral polyp as a tumor protruding from the external urinary meatus. The present case suggests a possible relation between Beckwith-Wiedemann and the onset of fibroepithelial polyps in the reno-urinary system during the neonatal period.
