Genitourinary Neurofibromatosis in a Child Presenting with an Enlarged Penis and Scrotum

Abstract
We report on a boy with genitourinary neurofibromatosis. The patient presented with bilateral hydronephrosis, and a markedly enlarged penis and scrotum. Laparotomy showed a mass occupying the small pelvic cavity. Histologically, the mass was a plexiform neurofibroma. The enlarged genitalia seemed to be caused by involvement of neurofibromatosis. The patient underwent a successful ileal conduit diversion.
