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
