title: Bladder Hamartoma in a Fetus: Case Report.
abstract: We present the case of the youngest reported patient with a bladder hamartoma detected prenatally by ultrasonography. Bladder tumors in newborns are rare, but a hamartoma should not be discarded among the diagnostic possibilities when evaluating a fetus or a newborn with a polypoid bladder lesion.
