Summary
Vasitis nodosa, a rare condition found in men desiring fertility after vasectomy, presents as nodules in the vas deferens. Histological examination reveals epithelial proliferation and sperm presence, potentially leading to re-canalization.
Area of Science:
- Urology
- Surgical Pathology
Background:
- Vasectomy is a common male sterilization procedure.
- Vasitis nodosa is a rare complication following vasectomy, characterized by nodular formations in the vas deferens.
Observation:
- Two cases of vasitis nodosa in men aged 47 and 40 years who previously underwent vasectomy and desired refertility.
- Spindle-shaped nodules were identified in the vas deferens during vaso-vasostomy procedures.
Findings:
- Histological analysis revealed focal proliferation of epithelial components forming glands with abundant sperm.
- Proliferative changes in smooth muscle bundles and spermatic granulomas were also observed.
- The condition shares histological similarities with salpingitis isthmica nodosa.
Implications:
- Vasitis nodosa requires differentiation from metastatic adenocarcinoma on histological examination.
- This condition may contribute to the re-canalization of the vas deferens, potentially impacting fertility outcomes.
