Diphallus with duplication of cloacal derivatives: report of a rare case

We report on a 3-month-old infant who had diphallus and a mass on the penis. On the undersurface of the mass there were 2 prolapsed mucosal lined tubes and catheterization revealed 2 blind tracts. The rest of the mass was covered by skin. On top of the mass was a pseudophallus with rugae on either side, suggesting formation of a scrotum. Duplication of the urethra and epispadias also were diagnosed. The bladder was single with good sphincteric control. We believe that the mass represents a duplication of the derivatives of primitive ectodermal and endodermal cloaca.
