LM DDx necrotic tumour, (residual) testicular tumour (e.g. germ cell tumour)

Testicular scar, also scar of testis, is a phenomenon that may arise in the context of treatment for a germ cell tumour[1] or result from the spontaneous regression of a (germ cell) tumour.[2]

General

  • Well-reported uncommon finding.
  • May result from the spontaneous regression of a (germ cell) tumour.[2]
  • Can be the result of trauma, (a prior untreated) testicular torsion or infection.

Gross

  • Tan-brown or white lesion.
  • Well-circumscribed.

Microscopic

Features:

  • Seminiferous tubules replaced by fibrosis.
    • Hyaline material with a relatively low cellularity and no nuclear atypia.
  • +/-Hemosiderin-laden macrophages.
  • Atrophic changes[2] - see testicular atrophy.

DDx:

  • Necrotic tumour.
  • Germ cell tumour, e.g. seminoma.
  • Regressed germ cell tumour - suggestive features:[2]
    • Distinct scar +/-germ cell neoplasia in situ (GCNIS) +/-coarse calcifications (intratubular).
    • Scar with prominent (small) blood vessels (weakly suggestive).
    • Scar with lymphoplasmacytic inflammatory infiltrate (weakly suggestive).

Images

  • Testicular scar - very low mag.

  • Testicular scar - low mag.

  • Testicular scar - intermed. mag.

  • Testicular scar - high mag.

  • Testicular scar - high mag.

  • Testicular scar - very high mag.

TESTICLE, RIGHT, ORCHIECTOMY:
- TESTICULAR SCAR REPLACING MANY OF THE SEMINIFEROUS TUBULES.
- REMAINING SEMINIFEROUS TUBULES WITH ATROPHIC CHANGES.
- BENIGN SPERMATIC CORD AND EPIDIDYMIS.
- NO EVIDENCE OF RESIDUAL GERM CELL TUMOUR.
- NEGATIVE FOR MALIGNANCY.
