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. © 2013 Japan Pediatric Society.
