The vas deferens is not seen commonly.

Classically develops post-vasovasostomy (vasectomy reversal).^[1]
- Seen in association with other surgical procedures.
- May be seen in the context of infertility (without prior vasectomy).
Some similarity to salpingitis isthmica nodosa.

Features:^[1]

Tubules in wall of vas deferens.
- Lined by columnar/cuboidal epithelium.
  - May have mitotic activity.
  - Nucleoli.
+/-Sperm granulomas.
- Histocytes - abundant foamy cytoplasm.
- Sperm - small black dots (~1 micrometer).

Notes:

Can be confused with prostatic adenocarcinoma:^[2]
- May "invade" vascular spaces - associated with elastosis (breakdown of elastic fibres^[3]).
