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).

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.
