title: Congenital prepubic sinus: is it a residual cloacal membrane and umbilicophallic groove?
abstract: We report two cases of congenital prepubic sinus (CPS) and discuss theories about its embryology and the etiology of its variants to improve the global understanding of this uncommon anomaly. Based on a review of the scant number of reported cases and our own experience, we postulate that CPS may be caused by a residual cloacal membrane and umbilicophallic groove and that its depth may determine the position of its ending.
