each penis and the prostatic urethra is situated in the skin between the two penises. In partial bifid phallus, the duplication of urethra, corpora cavernous and corpus spongiosum in one penis is incomplete, and there is only a corpus cavernosum and a spongiosum surrounding the functioning urethra in the other penis. Notable clinical cases Diphallia is usually accompanied by systemic anomalies; their extent varies, ranging from no associated anomaly to multiple anomalies including urogenital, gastrointestinal and musculoskeletal systems. Penile duplication also varies from a single penis with double glans to complete double penises. The meatus may be normal at tip of glans, hypospadiac, or epispadiac; the scrotum may be normal or bifid. True diphallia is more likely accompanied with associated anomalies and malformations compared with bifid phallus. Infants born with diphallia have higher death rate due to infections associated with anomalies. Complete true diphallia with associated anomalies A two-day-old male newborn, associated with complex genitourinary and ano-rectal malformation. He had imperforated anus, hypospadias, bifid scrotum, meatuses on both glandes, two bladders and two colons, and had normal testes, kidneys and ureters. Partial true diphallia or pseudodiphallia, without associated anomalies Partial true diphallia corresponds to pseudodiphallia. Pseudodiphallia is formed from erectile tissue only, undifferentiated and non-functional. It is independent of the normal penis and can be removed surgically without problem. This rare case was reported, based on the age of the 83-year-old man when diphallia was only detected then when he was hospitalised, and also because of the absence of other anatomical malformations. The small, immature and nonfunctional penis protruded on one side of the large, normal penis. The secondary penis had glans but without urinary meatus. Complete bifid diphallia with associated anomalies A 12-year-old boy, associated with bifid scrotum, epispadia and pubic symphysis diastasis. He had two separate penises, similar in size and shape, each penis had an epispadia urethral meatus. He had bifid scrotum, one testicle on each side of the scrotum. A bowel loop-like structure was over the pubis region. This structure had no communication with any other structures. He had a single normal bladder and ureter. Partial bifid diphallia without associated anomalies A 15-year-old boy, apart from having two penises, had normal external genitalia. His two testicles were within normal scrotum and normally positioned. He had two unequal sized glans at tip of a thick penile shaft, and only urinated through the larger glans. He had a
