Definition / general
  • Granulomatous condition of vas deferens that resembles spermatic granuloma of epididymis
  • Usually post vasectomy or herniorrhaphy
  • Occasionally associated with recanalization
Microscopic (histologic) description
  • Proliferating ductules and dilated tubules containing spermatozoa in wall of vas deferens
  • Also associated with small bundles of hyperplastic smooth muscle
  • Vas deferens may show irregular thickening
  • Ductules may connect with vas deferens (like diverticula or salpingitis isthmica nodosa but with inflammation and less smooth muscle hypertrophy)
  • May see perineural or vascular invasion by proliferating ductules
