This report details a rare case of complete diphallia in a teenage boy, featuring two fully developed penises with separate urethras. The case is unique, potentially being the first documented instance of diphallia alongside a third, distinct urethral duct.

Area of Science:

  • Urology
  • Developmental Biology
  • Medical Case Reports

Background:

  • Diphallia, a rare congenital anomaly, involves the presence of two penises.
  • While various forms of diphallia exist, the coexistence with additional urethral structures is exceptionally uncommon.
  • Understanding the embryological basis of such anomalies is crucial for diagnosis and management.

Observation:

  • A fifteen-year-old male presented with complete diphallia, each phallus possessing a distinct, fully formed urethra.
  • Histological examination revealed an additional urethral remnant in the right phallus.
  • A third, hypospadic perineal urethral duct with a mechanical sphincter was also identified.

Findings:

  • The patient experienced spontaneous bilateral simultaneous erections.

Related Experiment Videos

  • This case represents a unique presentation of diphallia with complex urethral duplication and a third urethral anomaly.
  • The histological findings provide detailed anatomical insights into this rare congenital condition.

    • Implications:

    • This case expands the known spectrum of genitourinary malformations.
    • Further research into the embryological origins of diphallia and associated urethral anomalies is warranted.
    • Such complex cases highlight the importance of thorough diagnostic evaluation in congenital urogenital abnormalities.
