True partial diphallia with associated penoscrotal transposition of two hemi-scrotums.

Diphallia or duplication of penis is extremely rare condition with a reported incidence of 1 in 5-6 million live births. Approximately around 100 cases of diphallia have been described in literature, each case have a unique presentation from associated anomalies. Clinically these patients can be classified into complete (true diphallia) or partial duplication. In true diphallia, each penis has 2 corpora cavernosa and 1 corpus spongiosum. If the duplicate penis is smaller or rudimentary with complete structure, it is described as true partial diphallia. The term bifid phallus is used if there is only one corpus cavernosum in each penis. Due to low incidence and varied presentation, not much is known about the underlying pathophysiology, management options, and outcomes. Here, we report a case of partial diphallia with associated penoscrotal transposition of 2 hemi-scrotums.
