A massive 420g magnesium ammonium phosphate scrotal calculus, measuring 8.7x7.2x6.5 cm, spontaneously expelled from a 93-year-old male. This is the world's largest reported intrascrotal stone, prompting discussion on diagnosis and etiology.

Area of Science:

  • Urology
  • Nephrology
  • Pathology

Background:

  • Intrascrotal masses and pain can indicate various underlying conditions.
  • Scrotal calculi are rare, with limited literature on their formation and characteristics.

Observation:

  • A 93-year-old male presented with a longstanding left intrascrotal mass and pain.
  • A large stone (8.7x7.2x6.5 cm, 420g) spontaneously expelled from the scrotum.

Findings:

  • The expelled stone was identified as magnesium ammonium phosphate.
  • This represents the largest intrascrotal calculus documented globally.

Implications:

  • Highlights the potential for significant calculus formation within the scrotum.
  • Emphasizes the need for thorough investigation of intrascrotal masses and pain.
